Purchase now: Bonfiglioli BX 80B 4 AC Electric Motor
Purchase now: Atlantechdrives provides you the BX 80B 4 230/400-50 IP55, a premium IE3 high-efficiency three-phase asynchronous AC induction motor manufactured by the global power transmission experts at Bonfiglioli. Belonging to the advanced BX series, this motor is specifically engineered to exceed stringent global energy efficiency standards (IE3 Premium Efficiency). By significantly reducing electrical and magnetic losses, the BX 80B 4 drastically lowers electricity consumption and operational costs in continuous-duty applications compared to standard legacy motors. Built on a standardized IEC 80B frame, it features a robust 4-pole stator winding design. Operating at 50Hz, it delivers a synchronous speed of 1500 RPM (typically running around 1440-1460 RPM under nominal load), making it the perfect, highly efficient prime mover for driving worm gearboxes, heavy-duty centrifugal pumps, and industrial ventilation systems. Encased in a durable, heat-dissipating housing with an IP55 rating, it effortlessly repels factory dust and low-pressure water jets.
Technical Specifications of the BX 80B 4 Motor
The BX series utilizes optimized electromagnetic design, high-grade copper windings, and precision low-loss electrical steel lamination. This premium construction minimizes internal heat generation, substantially prolonging the life of the Class F insulation and the internal bearings.

Expert Installation Advice: Star-Delta Wiring Protocols
Proper wiring configuration is absolutely critical for avoiding catastrophic motor failure upon startup. Expert Tip: The nameplate clearly designates the voltage as «230/400V». This indicates that the individual copper coils inside the motor 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, instantly melting the internal Class F insulation and causing a severe electrical short and potential fire hazard.
Maintenance and VFD (Inverter Duty) Compatibility
The BX 80B 4 is an «Inverter Duty» rated motor, meaning its premium insulation system is designed to withstand the rapid voltage spikes generated by Variable Frequency Drives (VFDs). Running this IE3 motor via a VFD yields massive energy savings by allowing you to match the motor speed to the exact demands of your process. However, because it is a TEFC motor, the rear cooling fan is driven by the rotor shaft. If you run the motor at continuously low speeds (below 25 Hz) under heavy torque load, the fan will not push enough air to cool the motor. Consider adding a forced-ventilation servo-fan if your application requires prolonged low-speed operation.
Frequently Asked Questions (FAQs)
Q: What is the difference between the Bonfiglioli BN, BE, and BX series?
A: These letters designate the efficiency class. The BN series represents standard efficiency, the BE represents high efficiency (IE2), and the BX series represents Premium Efficiency (IE3). The BX series uses the highest quality materials to provide the lowest possible operating costs over the lifespan of the machine.
Q: Can I safely 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 you must adjust your driven machine’s gearing to compensate for the higher rotational output.
