Embodiment Construction

[0074] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present disclosure as recited in the appended claims.

[0075] For some motors that require relatively large operating parameters, due to their large volume, they cannot meet the needs of users in some occasions where space is limited. In this scenario, the requirements of large working parameters and high load can be realized through the combination of two motors, in which the unified coordinated control of the two motors is required. In ...

Abstract

The invention provides a motor control method and device. The motor control method comprises that feedback signals of first and second motors are obtained; working parameters of the first and second motors are obtained according to the feedback signals of first and second motors respectively, and the working parameters include at least one selected from power and torque; and when the working parameters of the first and second motors satisfy a first preset condition, the working parameters of the first motor and / or the working parameters of the second motor are adjusted according to the preset condition. Thus, the working parameters of the motors match each other, load balancing of the two motors is realized, and higher power output is realized.

Description

technical field [0001] The present disclosure relates to the technical field of electric motors, in particular to a control method and device for electric motors. Background technique [0002] A motor is a device that converts electrical energy into mechanical energy. Generally, it is necessary to select the appropriate working parameters for the motor according to the load requirements, and then control the current and voltage to drive the motor. If the load demand is greater, a motor with greater operating parameters is required. In the related art, a motor with a large working parameter can be selected to meet the requirement. However, motors with large working parameters are generally large in size, and for some occasions with limited space, especially if the diameter of the motor is limited, it cannot meet the needs of users. Contents of the invention [0003] Embodiments of the present disclosure provide a motor control method and device, and the technical solutio...
