Embodiment Construction

[0028] At present, when the motor needs to work at a specified speed and temperature, a dynamometer (or other power source equipment) is connected to the output shaft of the motor, and the dynamometer drives the motor to run at a specific speed. Environmental equipment imposes high temperature conditions on the motor to make the motor run at a specific temperature. However, this method leads to a strong dependence of the motor on the dynamometer and external environmental equipment, thereby increasing the control cost of the motor. For this reason, the technical solution provided by the embodiment of the present application can solve the technical problems existing in the traditional motor speed and temperature control method, and reduce the control cost of the motor.

[0029] In order to make the purpose, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be further described in det...

Abstract

The present application relates to a motor control method, device, motor controller, system and storage medium. The method includes: determining a first control parameter of the motor according to the current speed and a target speed of the motor; determining a second control parameter of the motor according to the current temperature and the target temperature of the motor; Determine the target direct-axis current of the motor according to the change of a control parameter; determine the target quadrature-axis current of the motor according to the change of the second control parameter, and control the motor according to the target direct-axis current and the set The target quadrature axis current work. The method enables the motor to work independently at the specified target speed and target temperature independent of external conditions, and gets rid of the dependence on the dynamometer and external environmental equipment, thereby reducing the control cost of the motor.

Description

technical field [0001] The present application relates to the field of motor control, in particular to a motor control method, device, motor controller, system and storage medium. Background technique [0002] Under the background of today's energy shortage and increasingly serious environmental pollution, the development of electric vehicles is the common goal of the automotive industry all over the world. As the power source of electric vehicles, the motor needs to be controlled to work at a specific speed and temperature at the same time in many application scenarios. [0003] Taking the high temperature and high humidity test of the motor as an example, first connect the motor to be tested with the dynamometer and place it in the environmental chamber, apply high temperature and high humidity external conditions to the environmental chamber through the environmental equipment, and drive the motor to be tested through the dynamometer Run at a specific speed to make the m...
