Abstract

The present application discloses a Hall self-positioning method, device, equipment and system. In this method, after starting the motor, it is first detected whether the Hall signal is abnormal. If there is no abnormality, the Hall electrical angle is calculated, and the Hall position parameter is corrected according to the calculated Hall electrical angle. The Hall position parameter restarts the motor to check whether the motor is running normally. If it is normal, the corrected Hall position parameter is used as the correct Hall position parameter. In this way, the Hall self-positioning is realized and the Hall position parameter is corrected by itself. , the correct Hall position parameters are obtained, so that the motor can run normally, and it is easy to calculate the actual position of the Hall on the stator, and it can also make the motor run under the best efficiency condition, and improve the motor efficiency performance. And avoid complex manual debugging, positioning, etc., reduce the workload of developers, and shorten the development cycle of the project.

Description

technical field [0001] The present application relates to the technical field of motor control, and in particular, to a Hall self-positioning method, device, device and system. Background technique [0002] In the control scheme of the variable frequency motor, the Hall can be used to monitor the position of the rotor in real time. The Hall can be divided into components and ICs. According to the change of the magnetic pole polarity of the permanent magnet rotor, the corresponding level signal is output in real time (for example, facing the S pole, output high level), according to the change and combination of the three-phase Hall signal, to judge the position of the rotor in real time, so as to carry out the subsequent algorithm operation and motor control drive. [0003] But in actual development, sometimes we need to debug the Hall position parameters in the software, and according to the Hall position parameters, it is concluded that the current Hall (such as U-phase Hal...
