It is to install the starting resistance on rolling 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. it is composed of shell、starting liquid、moving magnetic boad、spring、connecting pillar、safety valve、exhausting valve etc. the starter has the advantage at small current ，large starting torque,adjustable the change to power and load so as to，protecting the motor. it can be widely used to start the winding asynchronous motor in ball miller、crusheruser 、blower fan、pump、beater、comprssor、crusher、defibrater、oxygenerator etc of bllization，chemical-industry、machinary、petroleum、mining、constrction、rubber、power station etc. it can stead of the collector ring，carbon brush of winding motor.
The start is easy to operate and install, which can reduce the expense of repire. it can take the motor to the best situation under adjusting the resistance 、torque and current. The starting current can be reduced from 7le to 1.6le under the condition of keeping the torque unchanged.it can start the motor with largest torque: 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 wasbess.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. 7、In order to prolong the using life, adopting the starting liquid to resisting rust、deteroprate、 freeze、boiling(boiling point is120℃). 8、To guarantee running safety, it needs to set the safey exhausting valve, which will be opened automatically when reaching the rated speed.
