Description

Driving and controlling integrated industrial motor

Technical Field

The invention relates to the technical field of motor equipment, in particular to a driving and controlling integrated industrial motor.

Background

Permanent magnet synchronous motors are very widely used in industry and operate on a principle similar to synchronous motors, which rely on rotating magnetic fields that generate electromotive force at synchronous speed. When the stator windings are energized by providing a three-phase power supply, a rotating magnetic field is generated between the air gaps, and the operation of the permanent magnet synchronous motor is very simple, fast and efficient compared to conventional motors. When the permanent magnet synchronous motor operates, the rotor iron core and the permanent magnet can generate eddy current loss, especially the permanent magnet synchronous motor with high torque density and high power density, a large amount of eddy current loss exists in the rotor, so that a large amount of heat can be emitted.

The prior art has the following defects:

1. The existing permanent magnet synchronous motor has the defects that the difficulty of directly installing a temperature sensor on a rotor is high because the rotor is in a high-speed rotating state during working, and a method for directly detecting the temperature of a stator winding to calculate the temperature of the rotor is generally adopted, but the data measured in the temperature measurement mode can cause inconsistent loss during heat conduction due to different factors such as different materials of air gaps between a stator and the rotor of different equipment, and the heat conduction has hysteresis, so that the error is large, and the current real-time monitoring requirement of the temperature of the rotor cannot be completely met;

2. The rotating speed of the existing permanent magnet synchronous motor can be regulated generally, but when the rotating speed of the motor is too slow, the rotating speed of a cooling fan connected with an output shaft at the rear end is reduced, the condition of insufficient cooling efficiency is very easy to occur in the motor, when the motor is at a high rotating speed, although the rotating speed of the fan is improved, if the motor is operated for too long, the cooling requirement is further increased, and at the moment, the motor possibly gives an alarm and needs to be stopped for waiting for temperature reduction, so that the conventional permanent magnet synchronous motor relying on cooling of the fan is difficult to meet the cooling requirement when the motor is operated at a low speed or is suitable for the ultra-long-time continuous working condition;

3. At present, some enterprises also improve the heat dissipation system of the motor, so that the rotation speed of the fan is not limited by the rotation speed of the motor, and the heat dissipation efficiency is improved, but the pure improvement of the rotation speed of the fan can solve the heat dissipation problem for a long time, but the heat dissipation problem can be caused by that most of the time of the motor is in an excessive heat dissipation state, the increase of energy consumption and the noise problem caused by high rotation speed are not considered, and the heat dissipation system is not practical.
