Abstract
The invention discloses a door machine control device, a door machine and a door machine control method. The inverter circuit is connected with the control circuit; the door motor is electrically connected with the inverter circuit; the star sealing relay is electrically connected to a connecting path of the inverter circuit and the door motor; when the control circuit detects that the door motor has a first fault, the control circuit enables a three-phase stator of the door motor to be in short circuit by controlling the inverter circuit, and then the motor rotating speed of the door motor is reduced; when the control circuit detects that the door motor has a second fault, the control circuit controls the speed reduction of the door motor by using the star sealing relay; wherein the first fault is a security fault, and the second fault is a non-security fault. The door machine control device can improve the safety performance of the door machine and reduce the cost.
