Brushless frequency sensitive rheostat there? Brushless frequency sensitive rheostat there at reasonable prices? Brushless frequency sensitive rheostat where good quality? Of course, is the dawn of brushless frequency sensitive rheostat. Why is the dawn of the brushless frequency sensitive rheostat? The starting equipment of the dawn of brushless frequency sensitive rheostat is a means of overcoming the shortcomings of a wound rotor induction motor with a slip ring, carbon brushes and complex starting device, while retaining the winding motor starting current, starting torque, etc. . 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. SUMMARIZE No brush No ring starter is to conquer the default of the rings, carbon brush, and complex starting sets on winging asynchronous motor, and is an equipment to reserve the advantage that small current and large torque of winging motor. JR, JZR, YR , YZR three phase winging stator ac asynchronous motor who use the starter of resistance, reactor, adjustable rheostat frequency sensitive rheostat, liquild resistance starter, soft-starterall can choose "No Brush and no ring to stead. Advantages brushless starter ring traditional, cumbersome, multi-touch components starting device removed, brushless loop operation, simple operation, easy installation and removal, can greatly reduce maintenance costs, and its advantages are: remove the 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, while maintaining the original motor operating characteristics. ADVANTAGE OF PRODUCTION No brush No ring starter remove the traditional Complicated , multiconduction component starting equipment. it is easy to opera
