Problems solved by technology

[0003] The soft start and speed control equipment currently used mainly include variable frequency motor start, hydraulic coupling, etc., but the cost of variable frequency motors is high, the maintenance technology requirements are high, and the complete no-load start of the motor cannot be realized, and it is not suitable for long-term operation at low speed; and The hydraulic coupler is mainly a soft start function, which cannot realize real-time speed regulation, and has a large power loss, large heat generation, and relatively low efficiency

Abstract

The invention provides a soft start speed regulation motor comprising an output shaft, a clutch, a hydraulic system, a motor shaft, a motor body, a cooling oil distribution disc and a case body. According to the soft start speed regulation motor, complete zero-load starting of the motor in a high-power working condition can be realized. In the starting process, a pressure variation characteristic of the hydraulic system to oil supply of a piston of the clutch is adjusted so that starting time and the starting characteristic of a working machine can be controlled at will. In the working process, a pressure value of the hydraulic system to the oil supply of the clutch is adjusted so that the working machine can work at any speed, and thus energy is saved. Meanwhile, power balance among motors can be realized for a combined driving system of multiple motors so that overload working of single motor can be avoided and the service life of the motor can be prolonged.

Description

technical field [0001] The invention relates to the field of industrial power transmission, in particular to a soft-start speed-regulating motor. Background technique [0002] For the occasion of starting a high-power motor with load, if the motor is directly started, the starting time is completely determined by the characteristics of the motor. In general, the starting time of the motor is short, and it is easy to form a large instantaneous impact. The starting current is very large, not only It will bring impact to the power grid, and will affect or even damage the motor and electrical lines; in addition, for some working machines, such as water pumps or fans, it is not necessary to work at full flow under certain working conditions. If an ordinary motor is used as the prime mover, then It cannot be realized, but using an adjustable speed motor to adjust the output speed of the motor according to the actual working conditions can greatly save energy. [0003] The soft st...
