Problems solved by technology

[0003] However, after the introduction of the constant power control strategy, since the input current is basically constant, when the vacuum cleaner sucks in a larger piece of dirt, the air inlet of the vacuum cleaner will be reduced, which in turn will lead to an increase in the internal vacuum degree, and the load on the fan blades will be reduced. Decrease, speed increase, resulting in increased loss, so that the suction efficiency of the vacuum cleaner is greatly reduced

Abstract

The invention discloses a dust collector, a motor, as well as a control method and a control device of the motor. The control method comprises the following steps: carrying out constant-power control on the motor; in the process of carrying out constant-power control on the motor, acquiring the current rotating speed of the motor and direct-current bus current of the motor; acquiring compensation amount of the direct-current bus current according to the current rotating speed of the motor; and according to the compensation amount, the direct-current bus current and a given value of the direct-current bus current when the motor operates at constant power, carrying out torque compensation control on the motor. With the method, the suction efficiency of the dust collector during hole-plugged operation can be effectively improved under the condition that the hardware cost is not increased.

Description

technical field [0001] The invention relates to the technical field of motor control, in particular to a control method for a motor of a vacuum cleaner, a control device for a motor of a vacuum cleaner, a motor with the control device and a vacuum cleaner. Background technique [0002] At present, high-speed and miniaturized brushless direct current motors (Brushless Direct Current Motor, BLDC) are more and more widely used, especially in the field of small electric tools (such as hand-held vacuum cleaners). When a small electric tool is powered by a battery, the battery voltage will gradually decrease with the use time. In order to enable the device to output a constant power, it is necessary to introduce a constant power control strategy during the battery voltage drop. [0003] However, after the introduction of the constant power control strategy, since the input current is basically constant, when the vacuum cleaner inhales a large piece of dirt, the air inlet of the va...
