Embodiment Construction
[0029] Such as figure 1 As shown in FIG. 1 , it is a flow chart of an elevator door machine door opening and closing torque control method according to an embodiment. The method comprises the steps of:
[0030] S110: Calculate the synchronous frequency f of the motor, and integrate the synchronous frequency f to obtain a coordinate transformation angle θ. The synchronous frequency f of the motor is related to the actual speed and slip frequency of the motor. When the motor speed is zero, the synchronous frequency of the motor is the slip frequency, which is also the output frequency fo of the motor. When the expected torque of the motor is determined, the output frequency fo of the motor is determined, and specifically has the following relationship with the rated slip frequency fs of the motor:
[0031] fo = ItRef × fs It .
[0032] Among them, ItRef is...
