DEFINITION

Classification: 318/760

Direct current primary winding braking circuit:

(under subclass 759) Subject matter wherein the means for applying a torque or force to the motor includes circuitry to apply direct current to the primary member so that the rotation of the motor causes the primary member to develop an induced voltage which causes a force in a direction opposite to the motor rotation to slow down or stop the motor.
