Abstract

This paper has advanced a kind of micro electromagnet motor with low rotational speed and high torque output: top-face- sway micro electromagnet motor. Its working principle is as following: under the rotating electromagnet's force, the motor's cone shape rotor makes pure rolling on the inner cone face of the stator and thus the output axle's rotation comes into being. Through testing, its rotation ranges is 20-860 rpm with larger than 10 (mu) Nm torque output. The result of the experiment show that with the same input power, this kind of micrometer has larger torque output than others' with the same volume. It has a wide applying prospect.
