Problems solved by technology

Although this structure can improve the requirements of different working conditions, because the two motors do not work at the same time, and the clutch is very large in size and weight in order to meet various working conditions, the power density of the system is very low, and due to the existence of the clutch , which makes the system less efficient, and also produces greater mechanical vibration and noise

Embodiment Construction

[0067] Such as figure 1 As shown, the main propulsion control of a ship is used to illustrate the variable structure motor system proposed by the present invention. In the present invention, the variable structure motor system includes a main controller 10, a variable structure driver 20 and an open winding motor 30. The main controller 10 receives control instructions and feedback information from the open winding motor 30, and generates Power drive and drive topology variable structure instructions. According to different operating conditions, the variable structure driver 20 transforms the drive topology structure according to the drive topology variable structure instruction. The variable structure driver 20 converts the open winding motor Multiple windings of 30 are connected in series to become a new one-phase winding. When the number of phases is 3×N+3, it is driven by 3×N+3 of the H bridge 42. After the control command is changed, it can be changed to N The new N+1 pha...

Abstract

The invention relates to an open winding variable-structure motor system, which comprises a master controller, a variable-structure driver and an open winding motor, wherein the master controller receives a control instruction and feedback information of the open winding motor, and generates a power drive instruction and a drive topology variable-structure instruction; and the variable-structure driver converts a drive topology structure according to the drive topology variable-structure instruction, can connect a plurality of windings of the open winding motor into a new one-phase winding in series and drives the open winding motor according to the power drive instruction. The open winding variable-structure motor system fully utilizes the advantages of variable structures, high power density and high reliability of the variable-structure driver and a multi-phase motor, can meet different work condition requirements, can effectively reduce the weight and the volume of a motor drive system in comparison with a multi-motor and clutch structure, effectively improves the power density and the reliability and eliminates mechanical noise.

Description

Technical field [0001] The invention relates to an open winding variable structure motor system, which belongs to the field of motors. Background technique [0002] With the development of high-power density magnets and power devices, the application of motor systems, especially open winding motors (permanent magnet independent winding motors), has been expanding, such as all-electric vehicles, all-electric tanks, and all-electric ships that have been developed. As the key power mechanism and propulsion power source of the above-mentioned system, the motor system is often complex and often changeable. For example, it often encounters high-speed, low-speed, light load, overload, normal, and fault conditions. [0003] In the prior art, in order to make the motor system meet the requirements of different driving conditions, multiple motors are usually coupled through a force or speed synthesizer, such as a high-speed motor + a low-speed motor through a clutch, and switch corresponding...
