Abstract

The invention relates to a speed regulating motor, in particular to a permanent magnetic speed regulating motor. The permanent magnetic speed regulating motor structurally comprises a motor body, a motor end cover sleeve is arranged on one side of a motor shaft of the motor body, a rotor shaft is arranged in the motor end cover sleeve through a bearing, and an electromagnetic speed regulating mechanism is arranged between the rotor shaft and the motor shaft and used for regulating the rotating speed of the rotor shaft. The permanent magnetic speed regulating motor can solve the problem that the speed of a current common motor is continuously adjusted or the speed regulating efficiency is low, the motor requiring a water pump, a fan and other load characteristics can be widely applied, the rotating speed of the motor can be changed along with load changes, and meanwhile energy is saved by about 60 percent.

Description

technical field [0001] The invention relates to a speed-regulating motor, in particular to a permanent-magnet speed-regulating motor. Background technique [0002] The workload of water pumps and fans often has the characteristics of non-constant power, and the characteristic curve of the work often represents the increase or decrease of the motor power with the increase or decrease of the speed. In industrial and mining enterprises, most of the motors with working characteristics similar to fans and water pumps cannot directly meet the requirements of the working conditions through the method of speed regulation. Generally, the method of installing regulating valves or air shut-off doors on the system is adopted to adjust to the required speed. speed. Contents of the invention [0003] In order to solve the problems in the prior art, the present invention provides a permanent magnet speed-regulating motor, which can overcome the problems of continuous speed regulation or...
