Brake Motors Bonfiglioli BX Series

Brake Motors Bonfiglioli BX Series Asynchronous IE3 Three Phase motor

BX Series asynchronous motors with aluminum frames are the right solution for a wide range of general purpose industrial applications. Both the IEC and Compact motor are available in IE3 efficiency classes according to the international standard IEC 60034-30. Furthermore, Bonfiglioli’s e-motors can be equipped with several options: protection class up to IP 56, tropicalized, corrosion-resistant paint, and anti-condensation heaters. Moreover, the BN/M and BX/MX motor Series are also able available in the BrakeMotor version with a selection of AC or DC brakes. To maximize our e-motor flexibility, all of them can be controlled with inverters.
