Embodiment Construction

[0046] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with specific embodiments of the present invention and corresponding drawings. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0047] In traditional refrigeration compressors, mechanical bearings are necessary components, and lubricating oil and a lubricating oil circulation system are required to ensure the work of the mechanical bearings. Among all the burned compressors, only 90% are actually caused by the failure of lubrication; while the mechanical bearing not only produces friction ...

Abstract

The invention discloses a motor control method and apparatus, a storage medium, equipment and a pulse extracting circuit. The motor control method comprises the steps of determining running-out frequency of a motor in running out; determining whether the running-out frequency is lowered to a set frequency or not; and when the running-out frequency is lowered to the set frequency, enabling the motor to perform shaft suspension stopping. By virtue of the scheme, the shortcomings of non-in-time shaft suspension stopping, easy shaft collision and influence to motor safety and the like in the priorart can be overcome; and the beneficial effects of in-time shaft suspension stopping, and avoidance of easy shaft collision and prevention of influence to motor safety can be realized.

Description

technical field [0001] The invention belongs to the technical field of motor control, and in particular relates to a motor control method, device, storage medium, equipment, and pulse extraction circuit; in particular, to a sensorless-based stop control method for a magnetic levitation compressor, and a device corresponding to the method, A storage medium storing instructions corresponding to the method, having the device, or a device capable of executing the instructions corresponding to the method, and a circuit for extracting a pulse signal corresponding to the idle speed of the motor in the device. Background technique [0002] The compressor is a driven fluid machine that raises low-pressure gas to high-pressure gas, and is the heart of the refrigeration system; it sucks low-temperature and low-pressure refrigerant gas from the suction pipe, and drives the piston to compress it through the operation of the motor. High-temperature and high-pressure refrigerant gas is dis...
