5 Mounting Arrangement The most common mounting arrangements for electric motors according to IEC and Australian Standards are detailed in the following table. The design of motors is such that they can be operated in all horizontal-mounting positions, providing consideration is given to the location of drain holes and bearing life EMT Motors are available in B3 foot mounted, B5 flange mounted, B14A face and some B14B mounting configurations. For confirmation of vertical operation refer to EMT Degree of Protection Degree of protection for all motors is IP55 as standard. All motors are fitted with a double lip oil seal or a labyrinth type rotating flinger at each end to enhance protection of the bearings against the ingress of dust, water, oils and other contaminants. All flanged motors are suitable as standard, for fitment to a wet mount gearbox Modifications to higher IP ratings such as IP56 or IP66 can be provided upon request Construction Motor stator frames and end shields are manufactured from high-quality castings, providing extreme strength particularly in applications where shock loads or vibration are present. Flanged end shields are a one-piece design that are internally strengthened to support the full motor weight in most horizontal or vertical mounting positions 5

6 Rotors The rotor windings and end rings are one-piece die cast aluminium with cooling fins to provide internal air movement. Shafts are made from high quality carbon steel. Drive shafts are Drilled and Tapped as standard and all shafts have Captive shaft keys Balancing Rotors are dynamically balanced and conform to limits of vibration severity grade normal (N) as specified in relevant IEC and Australian standards. The following table gives maximum allowable vibration grades relevant to motor frames. EMT motors can be supplied with either a reduced (R) or special (S) vibration level upon request Terminal Box All terminal boxes are a 2-piece flat cover type that can be rotated in any of 4 directions. Metric threaded conduit entries are provided on all frames as well as an additional knock out conduit entry on frames 63 to 132. (Refer to dimension data for number and size of entries.) A threaded cable gland is supplied with each motor. As standard, the terminal box material on frames type AHE 63 to AHE 160 is Alloy and for frames HE 160 to HE 450 is Cast Iron. As an option, a Cast Iron terminal box can also be fitted to motor frames 63 to 132 For specific terminal box measurements and available locations refer to the motor dimensional drawings on pages Vibration Grade N normal R reduced S special Speed ( rpm ) 600 to to 1800 >1800 to to 1800 >1800 to 3600 Maximum rms value of vibration velocity per Frames ( mm/s ) 63 to To to Shaft fitments such as couplings, pulleys, gears and fans should be balanced to prevent undue vibration and adverse effects on the motors bearing life. Any mounting bases or frames must be flat, rigid and solid Direction of Rotation All motors are designed and manufactured for bi-directional rotation. Reversing the direction of rotation is achieved by exchanging any two of the supply cables with each other Fasteners All fasteners are metric thread, electro-zinc plated for high corrosion resistance and suitably sized for rigid component mounting Nameplates All EMT motors are fitted with Stainless Steel nameplates. Rating and performance data is embossed and stamped to ensure it can remain permanently identifiable (AHE motors only) Bearings Motors from frame sizes 63 up to 225 are fitted with sealed for life type bearings providing enhanced protection against the ingress of dust and fluids. Motors from frame size 250 to 400 frame have flush through re-greasable bearings with a grease relief facility. Standard motors are fitted with high quality deep groove ball bearings, that are lubricated with lithium-based grease and are suitable for operation within an ambient temperature range of 20 degc to +55 deg C. Bearings are preloaded with a wave washer or pressure spring arrangement, which increases bearing life and reduces bearing noise. The life of bearings is dependent on various factors such as bearing load, motor speed, operating temperature and the purity of grease. Special bearing arrangements can be provided for high or low ambient temperature applications, or high thrust or centrifugal loads. In this instance refer to EMT For full listing of motor bearing sizes, refer to page 25 of this catalogue 6

7 Cooling Motors in standard form are Totally Enclosed Fan Cooled (TEFC IC 411) with external frame cooling fins to assist with heat dissipation. Cooling fans are one-piece fibrereinforced, multi-blade polypropylene or high pressure die cast alloy. Fans are keyed and circliped to the shaft to prevent movement. All fans are bi-directional and fan covers are rigid pressed steel. The standard motor cooling fan draws air through the end of the fan cover and provides a balanced airflow along the frame cooling fins. A motor must be installed it such a way as to ensure good ventilation and to avoid any obstruction of the designed air flow. As a guide, the following dimensions should be maintained IC 411 (Standard Motor) Self Ventilating Motor Enclosed machine externally finned with external shaft mounted cooling fan. Frame Size Minimum Distance (mm) MD IC 416 (Available as option) IC 418 (Available as option) Motor with Assisted Ventilation. Enclosed machine externally finned with independent external fan mounted inside fan cover. (Constant Velocity Cooling Fan) Motor with External Ventilation. Enclosed machine, externally finned with Ventilation provided by air flowing from the driven system. Forced Ventilation When required, all frame sizes can be supplied with cooling arrangement IC 416 for Variable Speed Drive application or IC 418 for Air Over application. See page 11 for further information Paint System After thorough cleaning and degreasing, all components are coated with an enamel based epoxy polymer paint finish that is sprayed electro statically to ensure uniform coverage. This treatment enhances the non-corrosive qualities of the frame. Special paint systems such as 2-pack epoxy for food industry or for corrosive environments can be provided upon request Power & The rated power of an electric motor is expressed in and indicates the mechanical power which is available at the drive shaft. The nominal torque at the motor s shaft is obtained by applying the following formula: T = x 9550 N Where T N = torque in Nm = rated power = rotation speed in rpm The rated power of electric motors is given for continuous operation at a voltage and frequency stated on the nameplate. 7

8 Duty All EMT motors are Continuous Duty (S1), based upon max ambient of 40 o C and altitudes below 1000 metres. If motors are operated at ambient temperatures beyond 40 o C and at an altitude over 1000m above sea level, their rated outputs will change and an approximate rating can be calculated by applying the % factors as indicated below Altitude m Ambient Temperature o C < For applications where motors are required to meet duty ratings from S2 to S9, the following approximate % factors can be applied Increased Power in % of the standard motor power. Type of Duty S2 S3 S4 to S9 Frame Size 60 min 30 min 10 min 60% DC 40% DC 25% DC 15% DC Refer 56 to to 160 to EMT 280 to Breakdown, Load Inertia and Load must be considered DC = Duty Cycle Insulation Classes Insulation materials are divided into insulation classes and each class has a designation corresponding to the temperature that is the upper limit of the insulating material under normal operating conditions, ensuring a long service life. If this limit is exceeded by 8-10 K, the life of the insulation will be approximately halved. The correct insulation of a motor winding is therefore determined by both the temperature rise in the motor and the temperature of the ambient air in which the motor is operating. The class F insulation and impregnation system is the most common used in industry today. This allows a temperature rise of 105k, measured by the resistance variation method and a maximum hot spot temperature value of 155 o C and also make these motors suitable for use in tropical environments and applications involving high vibration and high thermal variations B Temperature Limits for various winding insulating classes. F H Max. permissible temperature limits in o C Hot Spot thermal margin in K Permissible temperature rise for windings, at rated operation in K Maximum ambient temperature 8

9 Stator Windings Standard EMT motors are wound with Class F insulating materials, high quality copper wire with double thickness enamelling in modified polyesterimidic resins to resist high temperatures and fast switching spikes associated with Variable Frequency Drives. Winding designs generally limit the temperature rise to Class B specifications. EMT Motors are designed for use in tropical climates and provide good protection against corrosive gases and vapours Optional Over-Temperature Protection The following additional thermal protection can be fitted to all EMT motors upon request. Alarm Thermistors: A second set of PTC Thermistors with a lower temperature rating, can be installed to provide an over temperature alarm warning prior to any trip activation of the main thermistors Klixons or Motoprotectors: These devices are a normally closed bimetallic disc which opens when the winding temperature reaches limits dangerous to the insulation system of the motor. PT100 Thermocouples: These devices are platinum resistance thermometers which provide a variable linear resistance as the winding temperature changes. PT100 Thermocouples are particularly suitable for continuous temperature monitoring of a motor s windings and/or bearings Motors with Class H insulation systems or applications in hostile environments like chemically aggressive atmospheres, high humidity, high salt content or attack by microbes and insects are available upon request. Thermistor Protection EMT e-drive motors rated at 11 and above are fitted with one set of 3 x PTC Thermistors embedded into the windings during manufacture. Thermistors can also be fitted to motors in frame sizes 63 to 132 as an option. When fitted, the thermistor leads are terminated onto separate terminals located within the motor s main terminal box and a separate cable entry is provided for wiring connection. Upon request a separate terminal box can be fitted alongside the main terminal box The thermistor trip temperature determines the temperature at which the thermistor resistance rapidly increases. A control module must be used with the Thermistors and this is generally an externally excited solid state device that senses the thermistor resistance and switches contacts when the thermistor input resistance rises above a set resistance value. Due to their small size and heat sink construction, PTC Thermistors have very fast response times. Anti-Condensation Heaters Where motors are operating in areas of high condensation or left standing for long periods in damp conditions, they can be fitted with anti-condensation heaters. These are installed around the drive end windings and are usually energised when the supply to the motor is switched off. The Heater leads are connected via terminals in the motor s main terminal box or upon request, a separate terminal box can be fitted alongside the main terminal box. Heater power ratings normally used are shown in the table below. The standard supply voltage is V AC but other supply voltages can be provided upon request. Motor Frame Size Power ( W )

10 Terminal Connections EMT e-drive 3 phase motors have six terminal studs as standard. The windings are specially designed for Multi-voltage and Multi-frequency ratings making the standard motor suitable for many export markets. e-drive motors are compatible for use with single-phase variable frequency controllers up to 3kW and 3 phase variable frequency controllers throughout the entire range. Dependent on application, some de-rating may be required however motors can also be fitted with EMT Constant Velocity Cooling Units which provide continuous cooling air over the motor regardless of the output shaft speed. For more information, refer to EMT. The standard Direct on Line terminal connections for motors 3 and below are: Delta connected for: V 50Hz V 60Hz Star connected for: V 50Hz V 60Hz Soft Starting. This type of motor starter supplies a gradually increasing voltage, to ensure a smooth start by limiting the starting current for a preset starting time. The starter adjusts the voltage at required torque conditions therefore providing an energy saving operation. When a soft starter is used, it is important to ensure the torque characteristic of the motor meets the requirements of the driven load Star/Delta (Y/ ) Starting If the starting current of the motor is higher than the limit of power supply, a star/delta starter can be used. This means a motor wound for 400V Delta ( ) is started with the winding Star (Y) connected and then switched into Delta ( ) for running operation. This method reduces the starting current and torque to about 1/3 of the value for direct on line starting. In order to limit current and torque surges during switch-over from Star to Delta, the switch-over should not be carried out until the motor reaches at least 90% of its rated speed. Motors 4 and above are suitable for starting Direct On Line or via a star/delta starter if required. Standard DOL terminal connections are: Delta connected for: V 50Hz V 60Hz Star connected for: V 50Hz V 60Hz Single Speed Motor - Direct On Line Starting Star Connection ( Y ) Delta Connection ( ) 2 Speed Motor Connections EMT can provide 2 speed and multi-speed motors in both Variable and Constant ratings and speeds on short lead times. For two speed motor ratings and connections, refer to pages 18, 19 &

11 Inverter Duty Motors Today, inverter controlled AC cage induction motors are used for all kinds of automated plant and equipment and the infinite speed control of AC motors provides industry with substantial advantages including energy saving, process and manufacturing quality improvements. In general, a cage induction motor can be loaded at constant torque when the frequency is reduced and the primary voltage is changed in proportion to the frequency. Significant energy savings can be achieved when used on variable torque loads such as centrifugal pumps and fans. Large motors operating via a frequency converter can be subjected to high currents which often circulate through the motor bearings, rotor and frame, often resulting in premature bearing failure. For motors rated at 90 and above, we recommend the fitment of an Insulated Bearing at the non drive end which overcomes this problem. Both the EMT Constant Velocity Cooling Unit and an insulated bearing arrangement can be provided as an option for all EMT Motors. All EMT Motors are suitable for Inverter Duty application provided, Speed and Cooling limitations are taken into account. For constant torque applications where a motor operates continuously below 50% of its rated speed, it is important to ensure that sufficient cooling air is provided over the motor. This can be easily achieved by fitting the motor with an EMT Constant Velocity Cooling Unit thus providing continuous cooling air over the motor regardless of the output shaft speed. Induction Motor Synchronous Speeds - Effect on Airflow & for standard motors operating on Variable Speed Drives. Pole Frequency Cooling Problem Area (Suggest using EMT Constant Velocity Cooling Unit Generally considered to be a Safe Area of operation. Drop Off Area (Consider using motor with larger rating) Application and duty cycles for motors used with Variable Speed Drives may vary, therefore the above table should be used as a Guide only 1 1
