Abstract
The invention provides an intelligent sound-control brushless direct current motor, and relates to the technical field of motors. The intelligent sound control brushless direct current motor comprises a motor shell and an electric control bin, wherein the electric control bin is arranged above the motor shell, a stator is arranged in the motor shell, a winding is arranged in the stator, a permanent magnet rotor is rotatably arranged in the stator, a rotating shaft is arranged in the permanent magnet rotor, and the two ends of the motor shell are provided with an end cover and a sealing cover respectively. According to the invention, an electric control bin is arranged on a motor shell, a microphone receives voice data of an operator under the action of a voice control assembly, an audio recognition chip recognizes audio received by the microphone, reads preset instruction data in a storage and transmits the preset instruction data to a single-chip microcomputer, and the single-chip microcomputer starts an FET circuit according to an instruction, controls a winding to be electrified and opened to generate a magnetic field so as to drive the permanent magnet rotor to rotate, and can start a pulse width modulation chip according to the instruction to control the voltage at the two ends of the winding so as to adjust the rotating speed, so that voice control is facilitated, and more intelligence is achieved.
Description
technical field [0001] The invention relates to the technical field of motors, in particular to an intelligent sound-activated brushless DC motor. Background technique [0002] Brushless DC motor, abbreviated as BLDC in English, the stator (the fixed part) of the motor is a coil, or winding, and the rotor (the rotating part) is a permanent magnet, which is a magnet. According to the position of the rotor, a single-chip microcomputer is used to control each When the coil is energized, the magnetic field generated by the coil changes, so that the rotor is constantly seduced in front to make the rotor rotate; [0003] In the prior art, the control of brushless DC motors, such as the speed and direction of rotation, requires manual operation and regulation by operators, which is not intelligent enough and troublesome. Moreover, the existing brushless motors generate a lot of heat and dissipate heat. It is a big problem, therefore, the present invention proposes an intelligent s...
