Problems solved by technology

[0004] However, in the prior art, due to the structural problems of the motor itself, the motor has the problems of narrow constant power range and narrow high efficiency range (only one peak efficiency range)
This makes it impossible for the same motor to meet the three power demand environments at the same time

Abstract

The invention discloses a permanent magnet motor and a control method and system for the same. Each phase of the permanent magnet motor comprises low-speed windings and high-speed windings, wherein the low-speed windings of different phases are equal in number of turns and the high-speed windings of different phases are equal in number of turns; and the number of turns per phase in series for thelow-speed windings is greater than that of the high-speed windings in the same phase. According to permanent magnet motor disclosed by the invention, three different drive modes can be provided to bematched with vehicle power demands of different application scenarios. Compared with the prior art, the permanent magnet motor, the control method for the motor and the control system for the motor have the advantage more efficient and energy-efficient vehicle power output can be achieved.

Description

technical field [0001] The invention relates to the field of geological exploration, in particular to a permanent magnet motor and a control method and system for the motor. Background technique [0002] With the continuous development of electric motor technology, more and more vehicles use electric motors as power. [0003] In actual application scenarios, the power demand of the same vehicle is not limited to one application scenario. For example, the power demand of a vehicle can generally be divided into three scenarios: low speed and light load, high speed (low load) operation, and low speed and heavy load. That is, the vehicle has requirements for low-speed high-torque, high-speed constant power and wide-range high-efficiency areas for the power system. The most ideal power matching mode is to enable the power system to have three driving states at the same time to match the above three scenarios respectively. [0004] However, in the prior art, due to the structur...
