Title:
ELECTROMAGNETIC STEP-BY-STEP WOBBLING MICROMOTOR
Document Type and Number:
WIPO Patent Application WO/2010/035244
Kind Code:
A3
Abstract:
An electromagnetic step-by-step wobbling micromotor comprises an inner component and an annular component being external to the inner one. The outer component may be a stator and the inner component a rotor, or vice versa. The inner component has three or more poles with a winding on each pole, and an external surface facing an internal surface of the outer component. During the operation of the micromotor each winding is powered. The external and internal surfaces have toothed surfaces. Each tooth has a peak radius which is different from the valley radius.
