MGM Electric Motor B5

BM series motors are equipped with DC brake coil. DC brake coil is supplied through a rectifier located in the terminal box (standard voltage supply is 230V 50/60Hz). The rectifier is provided with over-voltage protection devices. The brake torque remains the same in both directions of rotation and the motor brakes without shaft axial sliding. Brake torque can be set loosening or tightening the adjustable springs (78) where available or in the presence of fixed springs, removing the central springs or replacing the springs with ones of another type. Never set the brake torque to a higher value than the one indicated on the motor nameplate. BM series motors are fitted as standard with a hexagonal hole on the shaft at non drive end to allow manual rotation. On request BM series motors can be provided with brake release return lever located on the motor side.
