Problems solved by technology

[0002] In recent years, most of the vehicles driven by electric energy, or hybrid vehicles with electric energy, use outer rotor motors as in-wheel motors. Since the use of outer rotor in-wheel motors for vehicle drive is in the research and development stage, no unified standard has been formed. The external rotor motors designed and used for each model with existing technology are all special types and cannot be used for all vehicles
[0003] Since the special-purpose external rotor motor is designed according to its specific use, although it achieves the effect of reasonable parameter design and good motor efficiency, it is necessary to design and develop various types of external rotor motors according to different uses of the motor. The production quantity is s

Embodiment Construction

[0073] Further details will be given below in conjunction with various embodiments shown in the accompanying drawings.

[0074] The present invention proposes an external rotor motor capable of controlled transformation of output parameters, such as figure 1 and figure 2 As shown, it includes a first outer rotor motor unit and a second outer rotor motor unit. The first outer rotor motor unit includes a first stator 7 fixedly mounted on a fixture 11, and a first rotor 6, 15 rotating on the outer periphery of the first stator. The second outer rotor motor unit includes a second stator 10 fixedly installed on the fixture, and a second rotor 9 rotating on the outer periphery of the second stator 10 . The second rotor 9 connects or disconnects the first rotor 6 , 15 in a controlled manner. When the first rotor 6 , 15 is connected to the second rotor 9 , the second rotor 9 rotates with the first rotor 6 , 15 . When the first rotor 6 , 15 is disconnected from the second rotor 9 ...

Abstract

The present invention puts forward a method for controlling an external rotor electric machine to change an output parameter and an external rotor electric machine. The external rotor electric machine is provided with two external rotor electric machine units therein, a mechanical one-way clutch or an electromagnetic clutch is utilized to realize that a second rotor is controlled to connect or disconnect a first rotor. The second rotor is controlled to connect or disconnect the first rotor according to service condition and operating characteristic requirements, so as to obtain the most suitable dynamic characteristics and regenerative braking characteristics, thus the high-output ultrathin external rotor electric machine is obtained with a low cost, and the output parameters of the electric motor have a large variation range, thereby overcoming the vicious cycle between a high cost and a low yield of the special external rotor electric machine in the prior art.

Description

technical field [0001] The present invention relates to motors suitable for passenger cars, transportation machines, industrial machines, household electrical appliances, etc., and particularly relates to an outer rotor motor in which a rotor rotates around a fixed stator. Background technique [0002] In recent years, most of the vehicles driven by electric energy, or hybrid vehicles with electric energy, use outer rotor motors as in-wheel motors. Since the use of outer rotor in-wheel motors for vehicle drive is in the research and development stage, no unified standard has been formed. The external rotor motors designed and used by existing technologies for each model are all special types and cannot be used for all vehicles. [0003] Since the special-purpose external rotor motor is designed according to its specific use, although it achieves the effect of reasonable parameter design and good motor efficiency, it is necessary to design and develop various types of externa...
