Problems solved by technology

[0004] First, increase the power of the motor so that the motor can cope with the needs of high power and high torque. This method will make the motor inefficient in the case of low power, and waste materials at the same time, which is uneconomical;
[0005] Second, use two motors, three motors or a group composed of multiple motors to drive, but the cost is high, the power coupling is complicated, and the torque of the magnetic group of the non-working motor also consumes the power of the system

Abstract

The invention relates to a high-efficiency platform combination motor. The high-efficiency platform combination motor consists of a frame-shaped shell, a motor shaft, at least one stator and at least one rotor, wherein each stator is provided with a stator heat sink; a rubber corrugated tube is arranged between the frame-shaped shell and each rotor; a sliding adjusting device capable of sliding along the axial direction is arranged on the frame-shaped shell and is used for adjusting the distances of the stator or the distances of the rotors; one-way bearings which are opposite to the motor shaft are arranged on one of the rotors or all the rotors; and the outside of the motor is connected with a plurality of relays. The high-efficiency platform combination motor has the advantages that an efficiency platform of a motor system can be expanded, and influences of reluctance torque of the motor on the system can be reduced; influences of cogging torque of the stators and the rotors on the system are small when the motor does not work; and the system cost can be reduced and is lower than a motor with the same functions in another scheme.

Description

technical field [0001] The invention relates to a high-efficiency platform combined motor used for electric vehicles, wind power generation, flywheel batteries and other motors for multi-working conditions. Background technique [0002] Once the size and winding of the motor are determined, the motor can only achieve high-efficiency operation within a certain range of power and speed, and its work efficiency is not high beyond this range. [0003] In actual work, the motor will work under multiple working conditions, which requires the motor to widen the high-efficiency area as much as possible. For example, the main power motor of an electric vehicle, when the vehicle works under different speeds, slopes, road conditions, and loads, the power point and speed point of the corresponding motor will be different. There are currently two ways to solve the above solutions: [0004] First, increase the power of the motor so that the motor can cope with the needs of high power an...
