Patents


ELECTROMAGNETIC STEP-BY-STEP WOBBLE-TYPE MICROMOTOR

Europe WO2010035244 / EP2380264 (A2), Issued October 26, 2011

Inventors:
Cesare Stefanini
Paolo Dario
Chiara Maria Carrozza
Sarah De Cristofaro

The present invention refers in general to variable reluctance motors and, more specifically, to variable reluctance step-by-step motors with wobble type behaviour. Even more specifically, the invention concerns motors of the aforementioned type with a diameter of less than 10 mm.
