Description
Technical Field
The utility model relates to the technical field of motors, in particular to a linear motor.
Background
A linear motor is a transmission device that converts electrical energy directly into linear motion mechanical energy without any intermediate conversion mechanism. It can be seen as a rotating motor, radially cut and flattened. The side evolving from the stator is called primary side, and the side evolving from the rotor is called secondary side. In practice, the primary and secondary sides are of different lengths to ensure that the coupling between the primary and secondary sides remains constant over the required range of travel. The linear motor may be a short primary long secondary or a long primary short secondary. The linear motor operates in a similar manner to a rotary motor. If the primary is stationary, the secondary moves linearly under the influence of electromagnetic thrust; otherwise, the primary performs a linear motion. At present, the most commonly used linear motors are cylindrical, flat-plate-type and U-shaped slot-type, and the power output is realized by generating an electromagnetic field through energizing a coil winding and generating relative electromagnetic thrust between a primary and a secondary.
