Purchase now: Bonfiglioli BE 80B 4 AC Electric Motor
Purchase now: Atlantechdrives provides you the BE 80B 4 230/400-50 IP55, a premium high-efficiency three-phase asynchronous AC induction motor engineered by the power transmission experts at Bonfiglioli. Belonging to the advanced BE series, this motor is specifically designed to meet stringent global energy efficiency standards (IE2/IE3), significantly reducing electricity consumption and operational costs in continuous-duty applications compared to standard efficiency legacy motors. Built on a standardized IEC 80B aluminum frame, it features a robust 4-pole stator winding design. Operating at 50Hz, it delivers a synchronous speed of 1500 RPM (typically running around 1420-1440 RPM under nominal load), making it the perfect prime mover for driving worm gearboxes, inline helical reducers, centrifugal pumps, and heavy-duty industrial blowers. Encased in a durable, heat-dissipating housing with an IP55 rating, it effortlessly repels factory dust and low-pressure water jets, ensuring maximum uptime in the harshest manufacturing environments.
Technical Specifications of the BE 80B 4 Motor
The BE series utilizes optimized electromagnetic design, high-grade copper windings, and precision low-loss electrical steel. This reduces internal heat generation, prolonging the life of the Class F insulation and the internal bearings.

Expert Installation Advice: Star-Delta Wiring and Efficiency
Proper wiring configuration is critical for avoiding catastrophic motor failure. Expert Tip: The nameplate clearly designates the voltage as «230/400V». This indicates that the individual copper coils inside the stator are engineered to handle a maximum of 230 Volts. If your industrial facility provides a standard 400V 3-phase power supply, you must arrange the brass terminal links inside the junction box into the «Star» (Y) configuration. This safely distributes the 400V across two coils in series. If you incorrectly wire the terminal block in the «Delta» (Δ) configuration and apply 400V, the coils will absorb almost double their rated voltage, melting the internal insulation and causing a severe electrical short. Furthermore, the BE series is «Inverter Duty» rated. Connecting this high-efficiency motor to a Variable Frequency Drive (VFD) will yield massive energy savings by allowing you to perfectly match the motor speed to the exact demands of your process.
Maintenance and Bearing Lifespan
The BE 80B 4 is a TEFC (Totally Enclosed Fan Cooled) motor, relying entirely on the rear plastic fan to blow ambient cooling air across the aluminum fins. During routine maintenance, you must ensure the fan cowl remains completely free of dust, lint, or debris blockages. Reduced airflow will cause the motor to overheat, rapidly degrading the factory-sealed bearing grease and leading to premature mechanical failure. Always protect your motor by integrating a properly calibrated thermal overload relay or Motor Protection Circuit Breaker (MPCB) set exactly to the motor’s Full Load Amperage (FLA).
Frequently Asked Questions (FAQs)
Q: What is the difference between the Bonfiglioli BN series and the BE series?
A: The BN series represents standard efficiency motors, while the BE series represents high-efficiency (typically IE2 or IE3) motors. The BE series uses more active materials (copper and steel) to reduce energy losses, lowering your factory’s electricity bill and running at cooler temperatures.
Q: Can I run this 50Hz motor on a 60Hz power grid?
A: Yes. Most Bonfiglioli motors can safely operate on a 60Hz grid. However, the synchronous speed will increase by 20% (up to 1800 RPM), and the running current characteristics will change slightly. You must adjust your driven machine’s gearing to compensate for the higher output speed.
