[0030] The motor 36 described in this patent is a device that converts electrical energy into mechanical energy. It uses an energized coil (that is, a stator winding) to generate a rotating magnetic field and acts on a rotor (such as a squirrel-cage closed aluminum frame) to form a magneto-electrodynamic rotating torque. Motors are divided into DC motors and AC motors according to the power supply used. Most of the motors in the power system are AC motors, which can be synchronous motors or asynchronous motors (the speed of the motor stator magnetic field and the rotation speed of the rotor do not maintain synchronous speed). The motor is mainly composed of a stator and a rotor. The direction of the force movement of the energized conductor in the magnetic field is related to the direction of the current and the direction of the magnetic flux lines (magnetic field direction). The working principle of the motor is the effect of the magnetic field on the force of the current, which causes the motor to rotate.

[0031] The working process is as follows:

[0032] 1. The operator first places the supporting roller on the fixed block 51, and first inserts the supporting roller into the right end of the fixed block 51. Then, the operator rotates the hand wheel 52, so that the screw rod 52 can rotate, so that the screw rod 52 cooperates with the clamping block 54, so that the clamping block 54 can move in the track 55, so as to clamp and fix the supporting roller, and then the device can be moved by the roller 2;

[0033] 2. After reaching the designated position, the motor 26 starts to work, and the output shaft of the motor 26 drives the rotating shaft 331 to rotate, so that the rotating member 332 cooperates with the protrusion 333, so that the limit member 334 drives the movable rod 335 to move up and down, so that the fixed block 51 will also move up and down, and when the fixed block 51 rises, the spring 42 pushes upward, thereby facilitating the operator to install the supporting wheel, and when the fixed block 51 descends, the spring 42 is compressed, so that the fixed block 51 can have a buffering effect.

[0034] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.
