About Company
Induction three-phase electric motors with integrated electro-magnetic brake
The motors are designed for drive of mechanisms, which need fixed stop in regulated time (electric hoists, treating machines, automatic transport and storage systems, etc.) Braking device shall be mounted from the side opposite to the side with free shaft end and provide fast motor braking in case of power switching off. In case if starts voltage supply on electric motor begins it’s unbraking. Usage of such motors reduces duration of cycle and increasing frequency of switching on. So, it facilitates to increasing of manufacturing intensity. The motors are designed to operate with three-phase AC.
