BS Single-phase asynchronous motors

Product catalog summary
General Information
Bonfiglioli, established in 1956, specializes in power transmission and control solutions. The BS series features single-phase asynchronous motors with options like thermal protection, extended shaft, and rain canopy, designed for industrial use and compliant with CEI/EN and IEC standards.
Standards and Compliance
The motors comply with European directives CEE 73/23 (LVD) and CEE 89/336 (EMC) for safety and electromagnetic compatibility, marked with the CE label.
Tolerances
Electrical tolerances include efficiency, power factor, slip, and torque variations. Mechanical tolerances ensure precise manufacturing of shaft ends, keys, and flanges.
Electrical Features
Designed for 230V-50Hz, the motors can be configured for other voltages. Suitable for continuous duty (S1), they require proper cooling and ambient conditions. Capacitors manage starting torque, with options for run-only or start-and-run configurations.
Insulation and Thermal Protection
Standard insulation is class F, with class H for harsher environments. Thermal protection prevents overheating using a bimetal disc.
Reversing and Mechanical Design
Motors can be reversed by switching wiring. They feature grease-packed bearings for maintenance-free operation, with terminal boxes and cable entries designed for easy connection.
Motor Mounting and Protection
Motors offer various mounting configurations, including vertical installation. They are IP55 protected, with IP56 for higher protection needs. Additional environmental protection is recommended for outdoor installations.
Additional Features
Options include a second shaft extension and rain canopy, though some combinations may not be compatible.
Rain Canopy Option
The rain canopy protects motors from solid bodies and dripping water, especially when installed with the shaft end down. It is incompatible with the second shaft extension option PS.
Rating Chart
The rating chart details parameters like breakdown torque, rated torque, starting torque, rated speed, and rated power for different motor models, including BS 56A, BS 63A, and BS 90S.
Dimension Drawings
Dimension drawings for shaft flange motors include measurements for models like BS 56, BS 63, BS 71, BS 80, and BS 90S, detailing components such as shaft diameter, flange diameter, and mounting holes.
Contact Information
Contact details for Bonfiglioli's headquarters and international offices in countries like Australia, Austria, Belgium, Brazil, Canada, China, France, Germany, and more are provided.
Company Overview

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. 2.1.3...

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 bimetal...

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 design...
