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。
Reducing end adjustment of stator windings and gap thickness can increase motor efficiency, reducing gap thickness can increase power factor also but will increase locked-rotor current ratio. 剪短定子绕组端部可调长度和减小气隙厚度也可以提高电机效率,同时减小气隙厚度有利于电机功率因数的提高,但会导致启动电流倍数的增大。
