Abstract

A ceiling fan, a ceiling fan motor control method, and a ceiling fan motor control device. The ceiling fan motor control method includes setting a rotational speed target value and a torque limit value associated with the ceiling fan motor. The processor controls the ceiling fan motor to operate. The operation information of the ceiling fan motor is obtained by the motor current sampling circuit. The current rotational speed and current torque of the ceiling fan motor are calculated by the processor according to the operation information. The processor is used to judge whether the current torque is greater than or equal to the torque limit, and when the current torque is greater than or equal to the torque limit, the constant torque control is executed, and when the current torque is less than the torque limit, it is further judged whether the current speed is The speed target value has been reached. When the processor determines that the current rotational speed reaches the rotational speed target value, the processor executes constant rotational speed control according to the rotational speed target value, and when the processor determines that the current rotational speed does not reach the rotational speed target value, the processor increases the torque current of the ceiling fan motor.

Description

technical field

[0001] The invention relates to a ceiling fan, a method for controlling a ceiling fan motor, and a control device for the ceiling fan motor, in particular to a ceiling fan, a control method for the ceiling fan motor, and a control device for the ceiling fan motor. Background technique

[0002] At present, the ceiling fan rotation control methods on the market all use the blade speed as the main control parameter, and use the constant speed control system to control the rotation of the blades. The target speed required to be achieved by different stages. However, such an approach will make the control program have to give different set speeds according to the different blades of the ceiling fan, which will cause great problems in technical service and commodity inventory.

[0003] Furthermore, because the ceiling fan motor and driver will produce many different changes according to the cross-matching of the blade size, shape, material, etc., but the set targe...
