Embodiment Construction

[0013] The technical scheme of the present invention is described in detail below in conjunction with accompanying drawing:

[0014] like figure 1 The motor speed control device shown includes a motor, a speed control module, and a speed control module; wherein, a magnetic ring is set on the motor shaft, the input end of the speed control module is connected to the motor, and the output end of the speed control module is connected to the input of the speed control module. terminal connection, the output terminal of the speed control module is connected to the motor;

[0015] The speed regulation module includes a Hall sensor, which converts the uniform magnetic potential generated by the magnetic ring when the fan rotates into an electrical signal and sends it to the speed control module. The Hall sensor is placed within a range sufficient to sense the magnetic potential generated by the rotation of the motor shaft.

[0016] The speed control circuit includes an 8051 single-...

Abstract

The invention relates to a motor speed regulation device, in particular to the motor speed regulation device for a fan. The motor speed regulation device comprises a fan motor, a speed measurement module and a rotating speed control module. A magnetic ring is sleeved on a rotating shaft of the motor. The input tend of the speed measurement module is connected with the motor, and the output end of the speed measurement module is connected with the input end of the rotating speed control module of which the output end is connected with the motor. When the motor rotates, the magnetic ring sleeved on the rotating shaft of the motor generates a magnetic potential, a Hall sensor converts the magnetic potential generated by the magnetic ring into an electric signal and transmits the electric signal to a singlechip, the singlechip counts the rotating speed of the motor, a countering result of the singlechip enters a comparator for comparison with reference voltage to judge whether the motor rotates too fast or too slowly, and the rotating speed of the motor is regulated by feedback regulation. The motor speed regulation device provided by the invention is easy to operate, and timely monitors and regulates the rotating speed of the motor.

Description

technical field [0001] The invention relates to a motor speed regulating device, in particular to a fan motor speed regulating device. Background technique [0002] The excitation coil of the motor is demagnetized, which will cause the motor to rotate too fast, which will cause the motor to overheat and cause production accidents. If the motor rotates too slowly, the insulation will be damaged. Timely detection and adjustment of motor speed can avoid motor damage. The existing rotating speed monitoring and adjusting device has complicated working process, so it is necessary to provide a simple and effective rotating speed monitoring and adjusting device. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a fan motor speed regulating device for the above-mentioned deficiency of the background technology. [0004] The present invention adopts following technical scheme for realizing above-mentioned purpose o...
