Abstract
An electric motor with an n-pole stator comprising a first stator winding and a second stator winding that can alternatively be supplied with current for the constitution of a pole-changeable electric motor. The supply winding is constituted by at least one turn of the first stator winding or of the second stator winding. Thus, a conventional winding design or coil design of the electric motor can be used to provide a supply voltage for electric equipment. The electric motor features an unchanged compact construction. Only at particular locations of existing stator turns current is tapped, such that a supply voltage of predetermined magnitude can be tapped based on the existing magnetic flux linkage during operation of the electric motor.
