Direct-drive reciprocating type single-phase brushless direct-current permanent magnet linear motor for fascia gun

The utility model relates to a direct-drive reciprocating type single-phase brushless direct-current permanent magnet linear motor for a fascia gun. A direct-current power supply is adopted, two pairsof power switch tubes supply power, a stator is provided with a permanent magnet, and a rotor groove is internally provided with a winding; the coil winding is divided into a forward connection winding and a reverse connection winding which are opposite in winding direction, and the current feeding directions are always opposite. The two pairs of power switches are divided into two groups, each group of power switches are synchronously opened and closed, and only one group of power switches can be in a closed state; reciprocating motion of the mover iron core is achieved through respective opening and closing of the two sets of power switches, and the circular shaft and the massage head are driven to do reciprocating motion. The reciprocating type single-phase brushless direct-current permanent magnet linear moto
