Abstract: Common soft starters have defects such as many setting parameters, inability to start frequently, need bypass after start, and short product life. This article introduces the performance of JRQ constant current soft starter and its various performance comparisons with star-delta and auto-coupling step-down starter, so as to have a more comprehensive understanding of JRQ constant current soft starter and provide electrical practitioners in the design and construction process. Provide reference in.

Keywords: constant current soft start; torque; fully closed loop;
