Slip ring motor starters Overview: Brushless starter ring is a way to overcome the shortcomings of the wound rotor induction motor with a slip ring, carbon brushes and complex starting device, while retaining the winding motor starting current, starting torque moment of the advantages of large starting equipment. Where the original resistance starter, reactors, frequency sensitive rheostat, liquid rheostat starters, soft starter starter JR, JZR, YR, the YZR three-phase wound rotor AC induction motor (variable speed, except with into the camera) Brushless starter ring "can be selected for replacement. Advantages: slip ring motor starters to traditional, cumbersome, multi-touch components starting devices remove the run Brushless ring, simple operation, easy installation and removal, can greatly reduce maintenance costs, the advantage is: get rid of slip ring, carbon brushes, brush box, brush box bracket, short-circuit loop and secondary loop systems in the frequency sensitive rheostat, AC contactors, time relay and other components, and keep the original motor operating characteristics. Main technical parameters: Rated frequency: 50Hz Rated voltage: 380V Motor power :15-125KW a light load: 0.6Me ≤ M ≤ 0.8Me, 2.5Ie
