| Title: |
Motor Assembly for Slowing Down Falling Speed of Stage Light Fixture on Power Failure, and Stage Light Fixture |
| Abstract: |
A motor assembly for slowing down falling speed of a stage light fixture on power failure includes a motor driver, an automatic transfer switch, a capacitive load, and an alternating current motor. In the case that the automatic transfer switch is energized, windings of the alternating current motor are kept connected to the motor driver, and in the case that the automatic transfer switch is deenergized, the windings of the alternating current motor are switched to be connected to the capacitive loads. The motor assembly according to the present disclosure can reduce the falling speed of the stage light fixture in case of the power failure. |
