5 1.2 - STANDARDS Technical norms Single-phase motors describedin this catalog are of the enclosedtype, fan ventilatedandwith run capacitor permanently connected. Motors are designed for use in industrial environments and are manufactured in accordance with applicable CEI /EN and IEC standards as listed in the following table: General requirements for rotating electrical machines CEI EN IEC Dimensions andoutput ratings for rotating electrical machines Classification of degree of protection provided by enclosures for rotating machines EN IEC CEI EN IEC Methods of cooling for electrical machines CEI EN IEC Classification of type of construction andmounting arrangements Terminal markings anddirection of rotation of rotating machines CEI EN IEC CEI 2-8 IEC Noise limits CEI EN IEC Ratedvoltage for low voltage mains power CEI 8-6 IEC European directives CEE 73/23 (LVD) and CEE 89/336 (EMC) Bonfiglioli single-phase motors meet the requirements of Directives 73/23/EEC (Low Voltage Directive) and 89/336/EEC (Electromagnetic Compatibility Directive) andtheir nameplates bear the CE mark. As for the EMC Directive, construction is in accordance with standards CEI EN Sect. 12, EN , EN Motors also meet the requirements of standard CEI EN Electrical equipment of machines. The responsibility for final product safety and compliance with applicable directives rests with the manufacturer or the assembler who incorporate the motors as component parts. 3

6 1.3 - TOLERANCES Electrical tolerances The following tolerances are permittedaccording to CEI EN : Efficiency (1- ) P 50 kw Power factor 1 cos 6 [min 0.02 max 0.07] Slip ± 20% (*) Locked-rotor current + 20% Locked-rotor torque - 15% + 25% Breakdown torque - 10% (*) ± 30% for motors with Pn 1kW Mechanical tolerances Dimensions andtolerances of shaft end, key andflange are in accordance with EN 50347, IEC , CEI-UNEL Shaft ends feature a threaded hole in accordance with UNI 3221, DIN 332. The shaft key is fitted in the keyway andsuppliedalong with each motor. The following table lists the tolerances for the different parts: Part Drawing letter Tolerance Shaft endd - DA j6 Key F - FA h9 Flange N j6 4

7 2.0 - ELECTRICAL FEATURES OPERATING CONDITIONS Voltage In their standard configuration motors are designed for 230V-50Hz supply. Upon request, motors can also be specifiedfor 115V-60Hz or 230V-60Hz supply Type of duty Motor outputs listedin this catalogue refer to S1 continuous duty. For motors operatedat duties other than S1, as per Norms CEI EN , please refer to Bonfiglioli s Technical Service for advise. Single-phase motors have greater losses when they run idle than in full load operation. Running idle for a long period is therefore NOT recommended Ambient temperature Catalog ratings are relevant to 50 Hz operation, under installation conditions as specified by standards CEI EN (temperature between -15 C and+ 40 C andaltitude above sea level 1000 m) Cooling Motors are cooledby external ventilation systems (IC 411 in accordance with CEI EN ) andare equipped with a plastic radial fan suitable for both directions of rotation. Installation must take into account a minimum clearance of the fan cowl from the nearest wall so as to ensure unobstructedair circulation. This will also facilitate routine maintenance operations Capacitors Configuration with run capacitor SC Single-phase motors featuring the run capacitor only feature starting torque considerably lower than rated torque (M S =30-70%M N ) andare therefore only suitable for applications calling for low starting torque requirements. Configuration with start and run capacitor DC For applications calling for higher starting torques, motors can be suppliedwith starting andrun capacitors attached. In this case a starting torque M S = % M N will be allowed. The starting capacitor is automatically cut off by the starter relay after approximately 1.5 seconds. For letting the starting capacitor discharging allow for a minimum 6 seconds rest time before reconnecting the motor. 5

8 2.3 - INSULATION CLASS Bonfiglioli motors use, as standard, class F insulating materials (enamelledwire, insulators, impregnation resins). For applications in the presence of aggressive chemicals or high humidity, contact Bonfiglioli Technical Service for assistance with product selection. On request, motors to insulation class H can be specified. CL F 155 C CL H 180 C 15 Hot spot allowance Temperature rise allowed Max. Ambient temperature Standard Option THERMAL PROTECTION Motors may be suppliedwith a built-in thermal protector preventing the stator windings from overheating due to poor ventilation or highly intermittent duty. Thermal protectors consist of a bimetal disc that, when the rated temperature (150 C) is reached, disconnects the contacts. As the temperature decreases below the set value, the contacts are reconnected automatically. Specify option D1 in the ordering code 6

9 2.5 - REVERSING Motors are suppliedwith run capacitor permanently connectedandcan be operatedin both directions of rotation. Motors can be reversedby switching the wiring, as shown in the diagram below, through a remote control switch. In the diagram below shaft are viewed from the drive end. W2 U2 V2 W2 U2 V2 U1 V1 W1 U1 V1 W1 L1 L2 L1 L2 Prior to reversing, make sure the motor is at standstill. AE For a facilitatedreversing through a simple switch, single-phase motors can be designedwith symmetrical windings and run capacitor permanently connected. For this arrangement specify option AE in the ordering code. This particular design is lower rated as compare to the standard arrangement and advise should be seeked with Bonfiglioli s Technical Service. W2 U2 V2 W2 U2 V2 U1 V1 W1 U1 V1 W1 L1 L2 L1 L2 Prior to reversing, make sure the motor is at standstill. 7

10 3.0 - MECHANICAL DESIGN BEARINGS Grease-packed, axially locked ball bearings ensure maintenance free operation. Nominal endurance lifetime L 10h exceeds 40,000 hours assuming no overhung loadon the shaft, andmounting position horizontal. The types of bearings in use are listedin the table below. DE NDE BS Z C Z C3 BS Z C Z C3 BS Z C Z C3 BS Z C Z C3 BS Z C Z C TERMINAL BOX The main terminal box houses 6 terminals for cable lugs connection andthe groundterminal for earth connection. On wiring the motor, refer to the schemes that are either locatedin the terminal box or in the operating instructions CABLE ENTRIES Terminal boxes feature entries for metric-thread cable glands (not supplied) in accordance with standard CEI EN Dimensions andlocations are as listedin the following table. cable entries anddimensions cable max.

11 3.4 - MOTOR MOUNTING Motors are available in the type of construction IM B5, IM B14 and derived versions in accordance with standard CEI EN , as shown in the table below. Motors may also be specifiedfor vertical mounting, however the name plate will only show the corresponding basic design version: If motor is to be installedwith the shaft endpointing down, the rain canopy is recommendedandshouldbe specifiedthrough the option RC. Flangedmotors can also be requestedwith reducedshaft andflange dimensions, specifying the design versions B5R or B14R. Relevant dimensions are listed in the table below: BS71 BS80 BS90 DxE- B5R (1) 11x x x B14R (2) 11x x x (1) flange con through holes (2) flange with threaded holes DEGREE OF PROTECTION Standard motors are IP 55 protected. A higher degree of protection, IP56, is available on request. Regardless to the degree of protection, motors for outdoors installation require extra protection against direct sunlight and in addition, when they are to be installed vertically down, a canopy protecting the motor from the ingress of water andsolidbodies (option RC) must be specified. 9

12 3.6 - SECOND SHAFT EXTENSION AT NON-DRIVE END Specify option PS in the ordering code PS The option PS is not compatible with the rain canopy RC preventing the ingress of water andsolidbodies. Refer to dimensional drawing for relevant shaft dimensions RAIN CANOPY Option RC The rain canopy is an optional device that protects the motor from the ingress of solid bodies and dripping water. It is highly recommendedwhen motor is to be installedwith the shaft endpointing down. Relevant dimensions are listed in the following table. The canopy is not compatible with the secondshaft extension, option PS. AQ V BS BS BS BS
