Abstract

The invention provides a balance block structure, a motor and a compressor. The balance weight structure includes: a balance weight body, the balance weight body has a first end and a second end oppositely arranged; the second end of the balance weight body is used to connect with the rotor; the balance weight body has a windward side and a leeward side, and the leeward side A mounting groove is provided, and the balance weight body is connected with the rotor through a fastener inserted in the mounting groove. The balance weight structure of the present invention solves the problem of wind wear loss of the compressor motor caused by the balance weight in the prior art.

Description

technical field [0001] The invention relates to the field of compressors, in particular to a balance block structure, a motor and a compressor. Background technique [0002] With the rapid development and wide application of refrigeration equipment, the rapid improvement of inverter compressor technology has been promoted. At present, the main and auxiliary balance blocks are arranged on the motor rotor of the commonly used inverter compressor, and the main and auxiliary balance blocks are designed to balance the eccentric part of the crankshaft. [0003] However, during the operation of the compressor, on the one hand, the refrigerant impacts the windward side of the balance block, resulting in a stagnation effect, resulting in a resistance torque that consumes the power of the motor and reduces the energy efficiency of the compressor. On the other hand, there are liquid oil droplets in the refrigerant. When the rotor is running, the windward side of the balance block will...
