Abstract

The invention provides a compressor preheating method, system, medium and equipment. The compressor preheating method comprises steps: a preheating instruction is sent to a driver through a main controller; whether the driver receives the preheating instruction or not is judged; if yes, a preheating signal is sent out, so that preheating current is introduced into a two-phase motor winding of thecompressor, and the compressor is preheated; and if not, no processing is conducted. The pulse signal is sent to the inverter switching device correspondingly connected with the two-phase motor winding of the compressor, so that the preheating current is introduced into the two-phase motor winding of the compressor to preheat the compressor, and the problems of unbalanced preheating and low preheating efficiency in the prior art are improved.

Description

technical field [0001] The invention belongs to the field of motor control and relates to a preheating method, in particular to a compressor preheating method, system, medium and equipment. Background technique [0002] At present, most of the motors used in air-conditioning compressors are permanent magnet synchronous motors without position sensors. When the permanent magnet synchronous motors without position sensors are started at low temperature, the viscosity of the lubricating oil will increase, which may cause the motor to be difficult to start. and changes in motor winding parameters. Since no position sensor requires motor parameters to estimate the rotor position, changes in motor parameters will cause inaccurate observation of the rotor position, which will easily lead to motor startup failure. In order to ensure that the motor can start normally, it is necessary to preheat the compressor. [0003] In the prior art, there are mainly two methods for preheating t...
