Frequency sensitive rheostat sales frequency sensitive rheostat proxy frequency sensitive rheostat the manufacturers frequency sensitive rheostat Price brushless frequency sensitive rheostat (frequency sensitive rheostat): starting resistance mounted directly on the motor shaft, the centrifugal force generated by rotation of the motor as the driving force, control the the size of the starting resistance, to reduce motor starting current, to increase the starting torque, wound rotor induction motor brushless running device. It mainly consists of the chassis, starting fluid, moving plate, spring, terminal, safety valve, exhaust valve, etc.. The starter has a starting current, starting torque, automatically adapt to changes in the power supply and the load to protect the motor and so on. Widely used in metallurgy, machinery, petroleum, chemical, mining, building materials, paper, rubber, water plants, power plants and other industrial areas, ball mill, crusher, fan, water pump, beater, air compressors, rolling mill, hot mill, oxygen machine motor drive device in wound rotor induction motor starting. It can replace the motor winding slip rings, carbon brushes starting device. Advantages starter brushless loop operation, simple operation, easy installation and removal, can greatly reduce maintenance costs. According to the characteristics of the mechanical load, automatically change the size of the starting resistance, adjust the starting torque and starting current of the motor in the best starting state. Keep the motor starting torque constant, the starting current from 7LE to 1.6LE and maximum torque starter motor. Starting device by the resistor evolved, with innovation as follows: 1, the fluid resistance brushless vacuum motor starters complete eradication of the use of slip rings, the carbon brushes caused by a variety of hazards. Remove the tradition, the complexity of the starting device, easy to operate. And will greatly reduce maintenance costs. 2, save installation space and the secondary circuit of the cable, to reduce the power consumption of the starting device, and energy savings. 3, the starting control is done automatically by the torque of the starter motor. Completely avoid 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. 4, the motor is running, such as stall phenomenon. As the motor speed decreases, the starter will automatically put into operation, to increase the motor torque to reduce the starting current purposes. 5, to overcome this defect stator control motor soft starter starting torque and starting current is proportional to the square of increase motor starting torque to reduce motor starting current, and maximum torque starter motor, with no operation of the brush, remove the traditional, cumbersome, multi-touch components starting device controlled motor soft starter, the base starting device power loss and motor start-up time than the stator reduced by more than 10 times, but the price of the starter less than the other 1/3 of the soft starter. 6, the starting resistor is mounted directly on the motor shaft, the use of a centrifugal force generated when the motor rotates as a driving force to control the size of the resistor to reduce motor starting current, to increase the starting torque, and to achieve the purpose of self-control operation of the brushless. 7, anti-rust, anti-deterioration, antifreeze (the sherbet -40), four anti-anti-boiling (boiling point of 120 degrees) starting fluid to improve the life of the starter.
