The invention relates to the technical field of motors, and particularly discloses a motor and a lifting platform slow descending device and method. The motor is used for driving the lifting platform to move and comprises a motor and a control circuit; wherein the motor comprises a first wiring terminal, a second wiring terminal and a third wiring terminal, and the control circuit comprises a first switch controller, a second switch controller and a third switch controller; one end of the first switch controller is connected with the first wiring terminal, one end of the second switch controller is connected with the second wiring terminal, one end of the third switch controller is connected with the third wiring terminal, and the other ends of the first switch controller, the second switch controller and the third switch controller are connected; the control circuit is configured such that when the motor is powered on, the first, second and third switch controllers are all switched off, and when the motor is powered off, the first, second and third switch controllers are all switched on. The slow descending scheme of the lifting platform is achieved through the motor which is low in cost and small in size.

    本发明涉及电机技术领域,并具体公开了一种电机、升降台缓降装置及方法。电机用于驱动升降台运动,包括:电动机和控制电路;其中,电动机包括第一接线端子、第二接线端子和第三接线端子,控制电路包括第一开关控制器、第二开关控制器和第三开关控制器;且第一开关控制器的一端与第一接线端子连接,第二开关控制器的一端与第二接线端子连接,第三开关控制器的一端与第三接线端子连接,以及第一开关控制器、第二开关控制器和第三开关控制器的另一端均相连;控制电路被配置为在电动机通电时,第一、第二和第三开关控制器均断开,在电动机断电时,第一、第二和第三开关控制器均闭合。本发明通过一种低成本、小体积的电机来实现升降台的缓降方案。
