ELECTRICAL MOTORS AND METHODS THEREOF HAVING REDUCED ELECTROMAGNETIC EMISSIONS

摘要

Motors and method of operation thereof operable in a running mode wherein the motor operates at a constant speed, and operable in a park mode wherein the motor is dynamically parked. The motor is housed within a housing and includes a rotating park disk configured to cause the motor to dynamically park. A park wire electrically couples the park disk to a switch configured to selectively set the motor to the running mode or the park mode, and a power wire electrically couples the park disk to a power source. Portions of the wires exit the housing so as to be disposed externally of the housing. The park wire is electrically isolated from the power wire during operation of the motor in the running mode and the park wire is electrically connected to the power wire during operation of the motor in the park mode.

主权项

1. An electrical motor operable in at least one running mode wherein the electrical motor operates at a constant speed and operable in a park mode wherein the electrical motor dynamically parks, the electrical motor comprising:
a housing; a rotating park disk within the housing and configured to cause the electrical motor to dynamically park; a park wire electrically coupling the park disk to a motor switch, the motor switch configured to selectively switch the electrical motor between the at least one running mode and the park mode, the park wire exiting the housing and being exposed at an exterior of the housing; and a power wire electrically coupling the park disk to a power source, the power wire exiting the housing and being exposed at the exterior of the housing; wherein the park disk is electrically isolated from the power wire during operation of the electrical motor in the at least one running mode and the park wire is electrically connected to the power wire through the park disk during operation of the electrical motor in the park mode.
