Abstract

The invention relates to a constant-power dust collector and a motor control method thereof. The bus voltage and three-phase current of a motor are collected; d-axis current and q-axis current are modulated, so that the power of the motor is accurately adjusted; and under the control of constant power, rotating speed can be further increased, namely, efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of motor control for vacuum cleaners, in particular to a constant power vacuum cleaner and a motor control method thereof. Background technique [0002] Existing constant-power handheld vacuum cleaners need to be equipped with various special devices (motor-specific ICs, position sensors, bus current detection devices, etc.) increased costs. [0003] In addition, in the existing motor constant power control method, the motor excitation current (d-axis current) is not modulated, resulting in premature power saturation when the motor is running at high speed, that is, when the motor does not reach the maximum speed, it has reached the rated power. As a result, the speed cannot be further increased, which affects the output efficiency of the motor. Contents of the invention [0004] The purpose of the present invention is to provide a constant power vacuum cleaner and its motor control method to solve the t...
