        1、It is from resistance starting equiment, which has below new characteristics:removing  the harm from ring and carbon brush.it saves repairing expense without traditional complex starting equipment.
         2、Saving the installation space and secondary loop cable,reducing the power waste of starting equipment, power wasteless.starting control is completed from starter  according to the speed of motor.
         3、It avoids the phenomena that some damage to motor and starter  from other equipment can not trace the starting process of motor by overload.
         4、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.
         5、Conquering the default that square of starting current is proportional to torque on stator controlled motor soft-starter with starting current. increasing the motor torque when reducing the current. adopting brushless running, it is 10 times to save the power and starting times.however, the price is not reached 1/3 than other soft-starter.
         6、The starting resistance is directly installed the rotoring shaft of motor, using the centrifugal power as driving, control the starting resistance to reduce the starting current, increase torque、 equipping the no brush self -controlled motor to winding asynchronous motor.

安裝及接線 
        1、先拆下電動機(jī)的護(hù)罩、滑環(huán)、碳刷、刷盒、刷盒支架及短路環(huán)裝置(有的電機(jī)無短路環(huán)裝置)等全部零件。
        2、拆卸滑環(huán)時，為防止后來接線時發(fā)生差錯，應(yīng)將同一相的兩根導(dǎo)線捆在一起。
        3、用游標(biāo)卡尺，分別測量電機(jī)的軸徑和起動器的孔徑、鍵寬、鍵高等尺寸是否相同，如有差異，應(yīng)及時同本公司聯(lián)系，以求解決。
