Abstract

The invention discloses a ceiling fan motor control method and device based on non-inductive FOC, and a ceiling fan. The ceiling fan includes a non-inductive FOC controller, a motor position detector for detecting the initial position of the motor rotor when the ceiling fan is stationary, and a motor position detector for collecting ceiling fan motor operation. The current acquisition circuit of the current, the ceiling fan motor control method based on the non-inductive FOC includes: the target operating current of the ceiling fan motor is preset to zero through the non-inductive FOC controller, and the current operating current of the motor collected by the current acquisition circuit is obtained; When the current working current determines that the motor is currently in a reverse state, the control motor enters a static state; the non-inductive FOC controller obtains the initial position of the motor rotor when the ceiling fan motor detected by the motor position detector is in a static state; according to the obtained motor rotor initial position and The target operating current of the ceiling fan motor controls the motor operation. The technical scheme of the invention realizes smooth start-up without reverse rotation of the motor in the ceiling fan.

Description

technical field [0001] The invention relates to the technical field of motor control, in particular to a ceiling fan motor control method and device based on a non-inductive FOC and a ceiling fan. Background technique [0002] Ceiling fans are common items in our daily life. In ceiling fans, motors are used to drive the rotation of fan blades. Traditional motor start-up control mainly uses the method of motor back electromotive force and comparator to detect the initial speed of the motor. If the motor is stationary, use pre-positioning. Arriving at the specified position will cause the motor to be pre-positioned to a fixed position, and due to the inertia of the fan blades swinging around the predetermined position, this process will last for a few seconds. The motor will perform open-loop dragging on the basis of pre-positioning and then switch to closed loop , at this time, the motor startup speed is relatively slow, and the acceleration process is not smooth. In order to...
