Abstract:
A motor includes a rotor assembly includes a rotor and a motor shaft secured to the rotor. The motor further includes stator coils. Circuitry of the motor includes electronic components that cooperatively operate to activate and deactivate the coils to cause the rotor assembly to rotate, and first and second power terminals. An electrically conductive outer housing surrounds the motor. An electrically conductive grounding tab is electrically connected to the first power terminal. The tab contacts a radially-inwardly facing surface of the outer housing to provide a electrostatic discharge path from the outer housing to the ground terminal.
