Research on Linear Motor for Linear Compressor
A novel moving-magnet linear motor was introduced which can produce high-frequency short stroke reciprocating motion, and it’s suitable to apply in linear compressor. The equivalent magnetic circuit model was established and the expression of driven force was given, then the impact the motor parameters made to motor performance was analyzed. The motor’s finite element model was established, the features of the air-gap magnetic field were studied, and the impact the length of the permanent magnet made to the motor stroke was analyzed. The foundation of the motor’s further optimization was laid by the results.
