Problems solved by technology

[0004] During use, the brake does not suck, there is severe vibration and squeaking sound, the friction plate is worn, the working gap increases, the torque drops, the low speed runs smoothly and the reliability performance is poor, and it cannot be used under a small starting current. High starting torque can be obtained, and it is not easy to maintain. When the motor runs at low speed and constant torque for a long time, the surface temperature of the motor is high, which exceeds the temperature rise of the motor, and there are certain potential safety hazards. Bearing damage, shortened service life

Abstract

The invention relates to a variable-frequency speed-regulating AC brake motor, and the motor is provided with a motor body. The center of the motor body is provided with an input shaft, and the external surface of the motor body is provided with a cooling fan. The input shaft is provided with an armature plate and an electromagnet, and a movable gap delta is disposed between the armature plate and the electromagnet. Screw rods which are connected fixedly through nuts are disposed between the armature plate and the electromagnet. A fuse nut is disposed between the screw rods, and a braking spring is disposed between the fuse nut and the armature plate. The motor is stable and reliable in low-speed operation, has no torque pulsation, can obtain a bigger starting torque under the condition of a smaller starting current, and is convenient in maintenance. The cooling fan which has independent power supply is used for forced cooling of the surface of the motor, and guarantees that the temperature rise of the motor does not exceed an allowed value when the motor is in long-time low-speed constant-torque operation. The motor is firm in installation, is good in rigidness, is flat in installation plane, cannot damage a bearing, and prolongs the service life.

Description

technical field [0001] The invention relates to an AC brake motor with frequency conversion and speed regulation. Background technique [0002] The rotor speed of the three-phase asynchronous motor is lower than that of the rotating magnetic field. The rotor winding induces electromotive force and current due to the relative motion between the rotor winding and the magnetic field, and interacts with the magnetic field to generate electromagnetic torque to realize energy conversion. The three-phase asynchronous motor operates It has good performance and can save various materials. [0003] Frequency conversion and speed regulation AC brake motors can be widely used in light industry, textile, mechanical transmission, electroplating production lines and other industries. This series of brake motors are suitable for all equipment that requires speed regulation, fast braking and accurate positioning; [0004] During use, the brake does not suck, there is severe vibration and sq...
