Brake Motors : Three-Phase - Standard Efficiency




Description
WEG Brake motors consist of an induction motor coupled to a disc brake, forming an integrated compact and robust unit. The unit is TEFC, and has the same performance characteristics of WEG TEFC range of motors. The brake is of sturdy construction with few moving parts which ensures long durability with a minimum of maintenance.
