Embodiment Construction

[0032] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific preferred embodiments.

[0033] Such as Figure 5 As shown, a method for automatically adjusting the efficiency of a brushless DC motor according to the load includes the following steps:

[0034] The first step is to input the target speed: input the required target speed in the motor input panel, and the VSP reading module will read the target speed.

[0035] The second step is to match the actual speed of the motor with the target speed: the speed detection module detects the actual speed of the motor, and through the control of the speed loop, the actual speed of the motor reaches the target speed in the first step, and the current detection module samples The current value when the target speed is reached, and recorded as lf.

[0036] In this step, the actual speed of the motor is controlled through the speed loop. When the actual speed of th...

Abstract

The invention discloses a method and control system for automatically adjusting efficiency of a DC brushless motor according to loads. The system comprises the motor and a motor built-in control board, wherein the motor built-in control board comprises a VSP reading module, a rotating speed detection module, a current detection module and an entrance angle adjusting module; the VSP reading module is used for reading rotating speed instructions; the rotating speed detection module is used for rotating speed detection; the current detection module is used for detecting and processing operation currents; and the entrance angle adjusting module is used for setting an entrance angle and substituting a set value into a motor system. According to the invention, by use of the method and such a structure, the VSP reading module reads a target rotating speed, the rotating speed detection module confirms an actual rotating speed of the motor, through adjusting the entrance angle, the actual rotating speed of the motor matches the target rotating speed, working currents of the motor is sampled, and an optimal efficiency point of the motor is adopted, such that the motor can be adaptive to different systems, the development time of the motor and the type number of motors required by clients are reduced, the time efficiency of development is greatly improved, and the cost is decreased.

Description

technical field [0001] The invention relates to a motor control method and a control system, in particular to a method and a control system for automatically adjusting the efficiency of a DC brushless motor according to load. Background technique [0002] The motors produced by motor manufacturers are used in various fields, and different fields have different loads and speeds. In order to make the motor have certain versatility and adapt to different loads, the rated power of the motor is usually very large. [0003] Traditional brushless DC motors usually require a host computer to control; or the control mode and control angle of the motor are fixed, so that there will be differences in performance under different loads and working conditions. However, the differential design of the motor and its control usually results in poor generalization of the motor. [0004] Therefore, in order to reduce the number of motor products required by different customer groups and the d...
