Description

technical field [0001] The invention belongs to the technical field of motor control, and in particular relates to a control device for a synchronous linear motor with a segmented primary winding structure. Background technique [0002] The linear motor does not need an intermediate conversion mechanism to directly convert electrical energy into the mechanical energy required for linear motion, and is widely used in fast response and high thrust systems. Compared with other types of motors, since linear synchronous motors have higher efficiency and power factor, they have better application prospects in practical applications; and with the development of permanent magnet materials, especially in high-performance permanent magnet After the emergence of the material NdFeB, the permanent magnet linear synchronous motor (PMLSM) has great advantages when compared with other high-speed precision systems due to its high power index, low loss, and fast response. It has broad applic...
