In this embodiment, the material of disc one 1 is stainless steel. Disk one 1 is an annular disk, and its center offers a central hole. The thickness of disk one 1 is relatively small, but must guarantee its support hardness, and the purpose of its setting is to fix these magnetic rings 4. A plurality of jacks are also opened on the disk one 1 , and these jacks...

Embodiment 2

[0055] This embodiment provides an array electromagnetic permanent magnet hybrid speed regulating device, which adds a current source on the basis of Embodiment 1. Wherein, the current source is used to generate direct current and deliver it to the coil assembly 5, so that the coil assembly 5 will immediately generate a corresponding magnetic field. The current source can change the magnitude and direction of the output current, thereby enhancing or weakening the magnetic field generated by the speed regulating device, thereby changing the rotational speed of the rotor.

Embodiment 3

[0057] This embodiment provides an array electromagnetic permanent magnet hybrid speed regulation method, which is applied to the array electromagnetic permanent magnet hybrid speed regulation device in Embodiment 1 or 2. Wherein, the speed regulating method includes the following steps.

[0058] (1) Provide direct current to the multiple sets of coil assemblies 5 to make the multiple sets of coil assemblies 5 generate a magnetic field together.

[0059] (2) When speeding up, make the direction of the magnetic field produced by each set of coil assemblies 5 consistent with the directions of the magnetic fields produced by the adjacent two magnetic coils 4, and increase the current in the multiple sets of coil assemblies 5 according to the required speed increase , so that the speed reaches the preset speed one. Wherein, the preset rotational speed one is the rotational speed after the acceleration.

[0060] (3) When decelerating, the direction of the magnetic field produced ...

Abstract

The invention discloses an array electromagnetic permanent magnet hybrid speed regulating device. The speed regulating device comprises a disc one, a disc two, a cylinder shaft, a plurality of magnetic coils, a plurality of sets of coil components and a plurality of connecting pieces. The second disc is arranged coaxially with the disc and separated from the first disc. The cylinder shaft is arranged coaxially with the second disc, and one end is fixed in the center hole of the second disc. A plurality of magnetic coils are evenly arranged on the same circular ring and installed on the disc one. An installation gap corresponding to a group of wire grooves is reserved between two adjacent magnetic coils, and the magnetic pole directions between the adjacent two magnetic coils are oppositely arranged. Each set of coil assemblies is installed in a corresponding installation gap, and the coils of multiple sets of coil assemblies are connected in series in sequence. After multiple groups of coil components are energized, the direction of the alternating magnetic field generated by each coil component is the same as or opposite to that of the two adjacent magnetic coils. The present invention can directly strengthen or weaken the permanent magnetic field by adjusting the current of the coil group to generate a corresponding electromagnetic field, so that the speed regulation process is more stable and the speed-up response is faster.

Description

technical field [0001] The invention relates to a hybrid speed regulating device in the field of speed regulating devices, in particular to an array electromagnetic permanent magnet hybrid speed regulating device. Background technique [0002] The existing permanent magnet speed regulating device adjusts the strength of the magnetic field by changing the gap between the magnetic disk and the conductor disk, thereby changing the transmission characteristics of the speed regulating device. In actual use, there will be a certain time delay in the adjustment of the gap, and at the same time, the structural stiffness will be reduced and the vibration will be increased. Contents of the invention [0003] In order to solve the technical problem of slow response in the existing speed regulating device, the invention provides an array electromagnetic permanent magnet hybrid speed regulating device. [0004] The present invention is realized by adopting the following technical solu...
