Abstract
An electrical motor includes a sleeve, a rotational assembly located in the sleeve, and a shaft rotatably mounted about an axis extending longitudinally through the sleeve. The motor also includes an endcap, and a brake mechanism located about the axis of the shaft, the brake mechanism including a spring and a first bushing, wherein the spring forces the first bushing against the endcap to create a static frictional torque between the first bushing and the endcap when the motor is in an off state.
