Linear motors are also called linear motors, linear motors, linear motors, and push rod motors. The most common types of linear motors are flat and U-groove, and tubular. The typical composition of the coil is three-phase, and the Hall element realizes brushless commutation.

Linear motors are often simply described as rotating motors that are flattened and work the same way. A forcer (rotor) is made by compressing a coil of epoxy together; the track is a magnet (usually a high-energy rare earth magnet) that is attached to the steel. The mover of the motor includes a coil winding, a Hall element circuit board, a thermistor (temperature sensor monitor temperature), and an electronic interface. In a rotating electrical machine, the mover and the stator require a rotating bearing to support the mover to ensure an air gap of the relatively moving portion. Similarly, linear motors require linear guides to maintain the position of the mover in the magnetic field generated by the track. The encoder of the rotary servo motor is mounted on the on-axis feedback position. The linear motor needs to feed back the linear position feedback device--linear encoder, which can directly measure the position of the load and improve the position accuracy of the load.
