The invention provides a heat dissipating device for a variable frequency motor. The heat dissipating device comprises an impeller with an edge overturned towards one side, a first mounting hole is formed in the center of the impeller, a plurality of second mounting holes are formed around the first mounting hole, a plurality of blade mounting holes are punched in the bottom of the impeller, and a vent hole is formed between two adjacent blade mounting holes; and heat dissipating blades are fixed in the blade mounting holes. The heat dissipating device provided by the invention has the advantages that the blade mounting holes are formed conveniently, and when the blades are mounted, the blades are mounted simply.
Description
technical field [0001] The invention relates to a heat dissipation device, in particular to a heat dissipation device for a variable frequency motor, and belongs to the technical field of motor preparation. Background technique [0002] Electric machinery (commonly known as motor) refers to an electromagnetic device that realizes the conversion or transmission of electric energy according to the law of electromagnetic induction. It is represented by the letter M (D in the old standard) in the circuit. Generally speaking, a motor is a machine that converts electrical energy into kinetic energy. Such a motor can be divided into a rotary motor that converts electrical energy into rotary motion and a reciprocating motor that converts electrical energy into linear reciprocating motion. Electric motors are installed as power sources in almost all products used in households such as refrigerators, air conditioners, washing machines, electric fans, and vacuum cleaners. [0003] Th...
