Abstract

The embodiment of the invention relates to the technical field of motor rotating speed adjustment, in particular to a method and a device for adjusting the rotating speed of a motor. The method for adjusting the rotating speed of the motor comprises the steps of obtaining a gear, a working voltage value and a working current value; judging whether the working current value conforms to a preset working current value interval or not according to the gear and the working voltage value; if not, adjusting the conduction angle of a silicon controlled rectifier until the working current value conforms to the preset reference table. Therefore, the working current value is firstly detected. When the working current value does not conform to the preset working current value interval, the voltage applied to the motor can be adjusted by adjusting the conduction angle of the silicon controlled rectifier in a silicon controlled rectifier control circuit until the working current value conforms to the preset working current value interval. The purpose of adjusting the rotating speed is achieved. No Hall IC needs to be arranged in the process, and the cost of the motor is reduced.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of motor rotation speed adjustment, and in particular, relate to a method, device, electronic equipment and storage medium for adjusting the rotation speed of a motor. Background technique [0002] In the control system of the mixer, it is usually necessary to ensure the stability of the rotation speed during stirring, that is, the uniform rotation speed must be ensured during the mixing process of different foods, so the general system has a rotation speed detection, which has certain requirements for the motor and the system, namely It is necessary to set a magnetic steel on the Hall device and the motor to ensure that the Hall chip is triggered by the magnetic steel to send a pulse signal when the motor rotates, and the pulse signal is input to the single-chip microcomputer to convert it into a rotational speed. speed, forming a closed loop. [0003] The current common solution ...
