Abstract
An apparatus and a method of manufacture of a DC electric motor operable over a range of voltage by virtue of a DC-DC regulator having an inductance provided by one or more windings on the stator of the motor. A conductor is wound about an interpole of the stator and coupled, as an inductance, to a voltage regulator circuit, allowing operation of the DC motor over a substantial range of input voltage.
