Title: Brushless motor

Abstract: A pulse width modulated brushless electric motor employs a conductive metalscrew or similar connector to create a common potential between the statorcore and the iron substrate on which the motor drive circuit is mounted.By approximately setting the common potential to, for example, the baseline of the power source and motor drive circuit, the noiseelectromagnetically generated by the pulse width modulation is suppressed.
