Linear motor

A linear motor disclosed by the present invention comprises a cover plate, a fixed seat assembly, a magnetic ring, a stainless steel sheet, a coil and a base. The cover plate is fixed on the base and assembles the fixed seat assembly, the magnetic ring, the stainless steel sheet and the coil between the cover plate and the base, and the fixed seat assembly comprises a bottom plate, a concentric sleeve and an insert. According to the present invention, the integral fixing seat of an existing linear motor is split into the bottom plate, the concentric sleeve and the insert, and thebottom plate, the concentric sleeve and the insert are riveted; and by adding a new part, namely the concentric sleeve, the assembly of the motor can be facilitated, the friction of the motor can be reduced, and the sound of the motor can be improved; and meanwhile, the thickness of the fixed seat is reduced on the basis of ensuring the strength, and the operation space of the linear motion of the motor is increased. 本发明公开的一种直线电机，包括盖板
