Description

A kind of heat treatment method of high-efficient compressor motor manufacturing process
Technical field
The invention belongs to full-technique non-oriented silicon steel applied technical field, more particularly to a kind of high-efficient compressor motor manufacturing The heat treatment method of process.
Background technology
With the energy-efficient further requirement of country, high-efficient compressor manufacturing enterprise generally use two ways is lifted Electric efficiency, the first is using core material of the non-orientation silicon steel of low-iron loss high-magnetic strength as rotor；Second is to adopt With common non-orientation silicon steel, appropriate heat treatment is then carried out to rotor to reach the final purpose for improving electromagnetic performance. Because requirement of the first way to non-orientation silicon steel material is high, high-efficient compressor producible corporationsípurchases cost will certainly be caused Increase considerably；And the second way can be heat-treated to rotor mass, increase less premise in motor manufacturing cost Lower raising electric efficiency, it is increasingly becoming the new trend of following high-efficient compressor motor development.
