Abstract

A method for controlling a ceiling fan motor includes: setting a target value of rotational speed and a limited value of rotational torque; controlling the ceiling fan motor to operate; obtaining operation information of the ceiling fan motor; calculating a current rotational speed and a current rotational torque according to the operation information; determining whether the current rotational torque is greater than or equal to the limited value of rotational torque; performing a constant rotational torque operation when the current rotational torque is greater than or equal to the limited value of rotational torque; determining whether the current rotational speed reaches the target value of rotational speed when the current rotational torque is less than the limited value of rotationaltorque; performing a constant rotational speed operation when the current rotational speed reaches the target value of rotational speed; and increasing 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...
