Claims

[Scope of utility model registration request]

In a DC linear motor, a drive coil is provided in a magnetic field created by a permanent magnet, and when a drive current is passed through the coil, the coil generates reciprocating motion. Both flanges are extended, bearings for the sliding shafts are provided near one end of both flanges, and a wire is wound around a bobbin with a guide groove for preventing rotation at the other end. , the sliding shaft inserted into the bearing has N-
1. A DC linear motor characterized in that the motor is magnetized so that S is reversed, and a detection head for detecting this magnetized state is fixed to the coil bobbin.
