2.0 - ELECTRICAL FEATURES 2.1 - OPERATING CONDITIONS 2.1.1 - Voltage In their standard configuration motors are designed for 230V-50Hz supply. Upon request, motors can also be specified for 115V-60Hz or 230V-60Hz supply. 2.1.2 - Type of duty Motor outputs listed in this catalogue refer to S1 continuous duty. For motors operated at duties other than S1, as per Norms CEI EN 60034-1, 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....

2.3 - INSULATION CLASS Bonfiglioli motors use, as standard, class F insulating materials (enamelled wire, 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. Temperature rise allowed 2.4 - THERMAL PROTECTION Motors may be supplied with a built-in thermal protector preventing the stator windings from overheating due to poor ventilation or highly intermittent duty. Thermal protectors consist of a...

2.5 - REVERSING Motors are supplied with run capacitor permanently connected and can be operated in both directions of rotation. Motors can be reversed by 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. Prior to reversing, make sure the motor is at standstill. AE For a facilitated reversing through a simple switch, single-phase motors can be designed with symmetrical windings and run capacitor permanently connected. For this arrangement specify option AE in the ordering code. This particular...

3.1 - BEARINGS Grease-packed, axially locked ball bearings ensure maintenance free operation. Nominal endurance lifetime L10h exceeds 40,000 hours assuming no overhung load on the shaft, and mounting position horizontal. The types of bearings in use are listed in the table below. jfi\BONFIGLIOLI RIDUTTORI

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 60034-7, as shown in the table below. Motors may also be specified for vertical mounting, however the name plate will only show the corresponding basic design version: If motor is to be installed with the shaft end pointing down, the rain canopy is recommended and should be specified through the option RC. Flanged motors can also be requested with reduced shaft and flange dimensions, specifying the design versions B5R or B14R. Relevant dimensions are...

3.6 - SECOND SHAFT EXTENSION AT NON-DRIVE END Specify option PS in the ordering code The option PS is not compatible with the rain canopy RC preventing the ingress of water and solid bodies. Refer to dimensional drawing for relevant shaft dimensions 3.7 - RAIN CANOPY Option The rain canopy is an optional device that protects the motor from the ingress of solid bodies and dripping water. It is highly recommended when motor is to be installed with the shaft end pointing down. Relevant dimensions are listed in the following table. The canopy is not compatible with the second shaft extension,...
