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.
