WZR controlled brushless motor soft starter new market controlled brushless motor soft starter is the starting resistance is directly mounted on the motor shaft, the centrifugal force generated by the rotation of the motor as the driving force to control the size of the starting resistance, to reduce motor starting current increase the starting torque, winding asynchronous motor controlled brushless run the device. It mainly consists of the chassis, starter fluid, moving a plate, spring, terminal, safety valve, exhaust valve. The starter has a small starting current, high starting torque and automatically adapt to changes in the power supply and the load, to protect the motor. Widely used in metallurgy, machinery, petroleum, chemical, mining, building materials, paper, rubber, water plants, power plants and other industrial fields, ball mill, crusher, fans, pumps, beater, air compressors, rolling mill, hot mill, oxygen machine motor drive device in wound asynchronous motor. It can replace the winding motor slip ring, carbon brush their starter. Controlled brushless motor soft starter Advantages: controlled brushless motor soft starter brushless acyclic running, simple operation, easy installation and removal, can greatly reduce maintenance costs, and according to the characteristics of the mechanical load automatically change the starting resistance size, adjusting the starting torque and current, so that the motor is in the state of optimum start. In the case of holding the motor starting torque constant, so that the starting current drops from 7Ie 1.6Ie, and the starter motor to the maximum torque. Evolved resistance starter device has the following innovations: 1, complete eradication of the use of slip rings, the hazards caused when the carbon brushes. Get rid of the traditional complex starting device, easy to operate, and reduce maintenance costs. 2, saving the cables of the installation space and the secondary circuit to reduce the power consumption of the starting device, and saves energy. Start control according to the speed of the motor starter auto-complete, completely avoiding the other starting device can not be based on the size of the load, automatic tracking motor was caused by damage to the motor or starter and other undesirable phenomena. Motor running process, if there stall phenomenon, with the reduction of the motor speed, the starter will be automatically put into operation, to increase the motor torque, reduce the starting current purpose. To overcome is proportional to the square of the starting torque and the starting current of the the stator control motor soft starter this defect, at the same time reduce the starting current of the motor to increase motor starting torque and maximum torque starter motor, using Brushless run, get rid of the traditional, cumbersome, multi-touch components starting device, the starting time of the power loss and motor starting device is more than 10 times less than the stator control motor soft starter, but starter price less than the other soft starter 1 / 3.6, the starting resistor is directly mounted on the motor shaft, using the motor rotation when the centrifugal force is generated as the driving force to control the size of the resistor, to achieve the reduction of the motor starting current, to increase the starting torque and achieve brushless Controls the purpose of running. 7, using the anti-rust, anti-deterioration, and the cold (the freezing heart -25 ° C), anti-boiling (boiling point of 120 ° C) of the four anti-starting fluid, to improve the life of the starter. Set safety exhaust valve to reach the rated speed, motor speed
