With very high locked-rotor torque and excellent performance in low frequency, it is suitable for situation with shock load to save power.
具有特高的起动转矩和良好的低频特性，特别适用于有冲击负荷的场合，在这种场合下使用比一般电机节电。
Increasing core length properly can raise motor efficiency and power factor, but it will reduce locked-rotor torque ratio and breakdown torque ratio.
适当增加铁心长度可以有效提高电机效率和功率因数，但会导致启动转矩倍数和最大转矩倍数减小。
The output torque of motor are not exceed maximum locked torque rotor.
为了使电机工作稳定，电机的输出转矩不能超过最大堵转转矩。
During the process of running, if it appears locked-rotor, the starter will automatically run for the reduction of motor speed to reach the goal of increasing the torque and reducing current of motor.
电机运转过程中，如出现堵转现象，随着电机转速的降低，起动器会自动投入运行，达到增加电机转矩，减少起动电流的目的。
