Description

technical field [0001] The invention belongs to the field of motors, in particular to a linear motor used for intelligent mechanical degree of freedom control. Background technique [0002] Linear motor, also known as linear motor, is a transmission device that directly converts electrical energy into linear motion mechanical energy without any intermediate conversion mechanism. It can be regarded as a rotating motor cut radially and developed into a plane. The side evolved from the stator is called the primary, and the side evolved from the mover is called the secondary. In practice, the primary and secondary are manufactured to different lengths to ensure that the coupling between the primary and secondary remains constant over the required travel range. Linear motors can be short primary and long secondary, or long primary and short secondary. When the primary winding is connected to the AC power supply, a traveling wave magnetic field will be generated in the air gap....
