摘要:
A braking action of movement of a support surface on an examination may be accomplished with a motor. The examination table includes a base, a support surface moveable with respect to the base, and a motor having a rotor and a stator. The motor is coupled to the support surface and configured to move the support surface. A motor controller of the examination table is in electrical communication with the motor. The motor controller is configured to brake the movement of the support surface by terminating power to a plurality of windings of the stator of the motor for a predetermined amount of time, and, selectively activating a subset of windings of the plurality of windings of the stator for a predetermined amount of time.
