ELECTRIC MOTORS. Selection. Starting torque and nominal torque

Transcription

1 SELECTION PROCEDURE The output powers published overleaf are based upon continuous maximum rating conditions. Therefore design factors for above average running periods do not normally affect the selection.these ratings assume a normal operating condition at an ambient temperature not exceeding 40 C at an altitude below 1000 metres. Correction factors for other conditions are given below. Permitted Frequency of Starts When a motor is stopped and restarted too frequently, overheating will occur. Specific results depend upon the relative inertia of the motor and of the driven machine so it is not possible to publish meaningful figures. If in doubt contact your local Fenner authorised distributor. Noise and Vibration The FM:P range of motors comply with international recommendations relating to maximum permitted noise levels. All rotors are dynamically balanced, with a key fitted, in order to ensure that vibration levels do not exceed class N, ISO 373. Mounting Ratings for Ambient Temperature & Altitude Power available as % of published figure at following altitudes (metres) Ambient Below Temp C Motor bearings are charged with grease suited for ambient temperatures in the range 30 C to 55 C. Selection Starting torque and nominal torque M S: The starting torque is the mechanical torque developed by the motor with the rotor locked. M N: The nominal torque is the mechanical torque that the motor is developing when it is giving its nominal power and speed. Starting current and nominal current I N: The nominal current is the current that the motor is developing at nominal power and nominal voltage. I S: The starting current is the current that the motor is developing when the rotor is locked. Bearing Life Bearing life depends on factors such as bearing load, rotation, speed, and operating temperature of the bearing. Standard electric motors are fitted with bearings of sufficient capacity for normal overhung or axial loads. If bearing capacity is in doubt consult your supplier with full application details. Mounting Positions Although motors are normally stocked in either the B3 or B5 assembly format, it is in most cases possible to mount them in any of the alternative mounting arrangements shown in the motor mounting arrangements table without further modification, but it is essential that the actual mounting is specified at the time of order. Fenner High Eficiency Motors Specification Class F Insulation Class F insulation with class B temperature rise. IC 411 Cooling Surface cooled to IC 411 according to IEC IP55 Protection Protected to IEC 34-5 for IP code and achieves an IP55 classification. Motor Frame Manufactured in high strength aluminium up to 13 frame and high grade cast iron 160 frame and above. Stator Constructed from high grade electrical steel laminations. Rotor Dynamically balanced squirrel cage rotor is made from cast aluminium shrunk onto the shaft. Bearings and Seals Deep groove ball bearings with shields are normally used. Larger frames use NU roller bearings on drive end. Warranty and Support The comprehensive 1 month warranty is complemented by the full technical support from your local authorised distributor.

15 Electrical Connections Electrical Connections Connection cables and earthing requirementnts should conform to IEE regulations. It is recommended that a suitable overload is fitted to protect the motor windings. Line fuses only protect the cables from short circuit not the motor. Ensure that all terminals are tight and that the correct terminal arrangements are observed. All motors are capable of running with two voltages. Smaller motors are suitable for a 30/400V supply and larger motors are suitable for a 400/690V supply. It is only possible to use a 400V Star/Delta starter on motors that are wound 400/690V - for this type of start, links must be removed.
