Prototype pcb assembly for brushless self-control motor liquid resistance starter

The prototype pcb assembly for brushless self-control motor liquid resistance starter directly installs the starting resistor on the rotating shaft of the motor, and uses the centrifugal force generated when the motor rotates as the power to control the value of the starting resistor, thereby reducing the starting current of the motor, increasing the starting torque, and winding the wire which is the device for realizing brushless automatic control operation of wound asynchronous motor. It is mainly composed of casing, starting fluid, moving plate, spring, binding post, safety valve, exhaust valve etc.

The starter has the characteristics of small starting current, large starting torque, automatic adaptation to changes in power supply and load, and protection of the motor. Widely used in metallurgy, machinery, petroleum, chemical, mining, building materials, paper, rubber, water plants, power stations and other industrial fields of ball mills, crushers, fans, pumps, beaters, air compressors, rolling mills, hot mills, Starting of a wound-type asynchronous motor in a motor drive device such as an oxygen generator.

Product advantages

The operation is simple, the installation and disassembly are convenient, the maintenance cost can be greatly reduced, and the value of the starting resistor can be automatically changed according to the characteristics of the mechanical load, the starting torque and the starting current are adjusted, and the motor is in an optimal starting state.

The main technical parameters

1. Rated voltage: 380V, 6KV, 10KV, with motor power: 130-2000KW.

2, starting characteristics:

a. Light load: 0.6Me b. Medium load: 1Me c. Heavy load: 1.5Me

3. The motor realizes constant torque and constant current starting. The starting current and starting torque can be adjusted steplessly according to user requirements.

4, to achieve the brushless operation of the winding motor, completely eradicate the various hazards caused by the usage of slip rings, carbon brushes, save the start control cabinet and secondary cable, so that the cost of the wound motor starter is reduced by 70%, running Maintenance work is reduced by 90%, and the reliability of the motor and its control device is improved more than doubled
