Abstract
An inchworm motion linear motor based on an electromagnetic clamping device in a technical field of electromagnetic motors includes more than two electromagnetic clamping mechanisms which are arranged in pairs and mutually symmetrically connected. The electromagnetic clamping mechanism includes magnetic field generation devices, rolling bodies, an output shaft and a shell body, wherein the magnetic field generation devices are fixedly arranged outside the shell body; and the shell body and the rolling bodies are sleeved outside the output shaft in sequence. The inchworm motion linear motor based on the electromagnetic clamping device can be manufactured into an electric control super-large clamping force device by sensitively controlling mechanical rigid locking and releasing states with electromagnetically. The clamping device can be manufactured into a driving device or the linear motor with super-large load and precise movement.
