无刷无环启动器 无刷无环起动器（Brushless acyclic starter brushless acyclic starter） Brushless acyclic starter brushless acyclic starter.Txt Brushless acyclic starter brushless acyclic starter Summary Wound rotor asynchronous motor (also called slip ring motor) special QXQ brushless ring starter, Henan is the new starting liquid equipment Co. Ltd. the company nearly ten years of development of a new generation of energy-saving motor production equipment after starting. This product not only makes the traditional winding rotor motor get rid of the complex and complex starting system, but also solves the main problems of eddy current loss, leakage reactance, starter heating and so on. The starter is installed a step-down device for synchronous operation in the rotor of the motor, the motor speed and the inertia effect, set the vacuum short circuit switch, the short circuit switch using internal vacuum interrupter design, eliminate the phenomenon of the occurrence of starter burn caused by creepage. When the motor reaches the rated speed without using the starter, the short winding device automatically disconnects the coil winding, not only saves the electric energy, but also does not heat the coil winding, and ensures the stable operation of the starter. The advantages are: remove the slip ring, brush, brush box and short circuit ring, remove the two loop system of frequency sensitive rheostat, AC contactor, time relay and other components, based on the realization of the motor brushless ring operation, actually maintain the operating characteristics of the original starter, it prolongs the service life of the motor at the same time. Ensure the service life of the starter. Brushless variable resistance starter will be widely used because of its excellent starting performance, low price, self adaptability to power and load, small volume, energy saving and convenient operation and maintenance.
