Problems solved by technology

Although this motor has greatly improved the electromagnetic braking effect and its power per unit volume, there is a certain torque dead zone during the operation of the single-phase reluctance motor, which increases the vibration and noise of the motor caused by torque ripple.
Also because the starting winding of the rotor needs to be energized, there are corresponding disadvantages due to the addition of brushes.
[0006] Moreover, the general motor only realizes rotation or linear motion, and cannot organically combine the two, nor can it artificially change the polarity or direction of the magnetic field inside the motor. Therefore, it is urgent to design a rotatable, movable Dual Function Motors for Linear Motion

Embodiment 1

[0036] The technical scheme adopted in the present invention is:

[0037] Such as Figure 1-4 As shown, a dual-function motor that can rotate and move linearly includes an outermost casing 1 and end covers 2 arranged at both ends of the casing 1. A bearing 5 is fixed in the middle of the end cover 2. Between the two bearings 5 A supporting rotating shaft 3 is arranged between them, and two brackets 4 are fixed outside the casing 1 for supporting the entire motor.

[0038] Further, as Figure 5-13 As shown, a plurality of stator blocks 6 are evenly inlaid inside the casing 1, coils 7 are wound on the stator blocks 6, a rotor core 8 is fixed on the rotating shaft 3, and two rows of permanent magnets are inlaid in radially symmetrical positions on the outer ring of the rotor core 8. 9. In the axial direction of the rotor core 8, three rows of permanent magnets 9 are equidistantly fixed, and the outer magnetism of the permanent magnets 9 is set as an N pole, and the inner magnet...

Embodiment 2

[0044] The difference between this embodiment and embodiment 1 is:

[0045] The bearing 5 located at the rear of the dual-function motor is provided with a shaft connection part, which connects the shafts 3 of the two dual-function motors, so that the two dual-function motors can be connected in series. Since the rotor core 8 is installed on the shaft 3 Above all, the rotating shaft 3 can rotate without hindrance inside the motor, and the rotation of one motor drives the rotation of the motor connected in series, not only the transmission of the rotation of the motor can be realized, but also the alternate work of the motor can be realized.

Embodiment 3

[0047] The difference between this embodiment and embodiment 1, 2 is:

[0048] The inside of the coil 7 is wrapped with a permanent magnet 9, and the magnetic poles generated after the coil 7 is energized are in the same direction as the magnetic poles of the permanent magnet 9; the permanent magnet 9 is embedded inside the coil 7, the purpose is to increase the magnetic force of the coil 7 after energization, so that the coil 7 has more Strong magnetic force can increase the speed range of the motor to meet wider application requirements.

[0049] In the present invention, the rotatable and linearly movable dual-function motor designed by the present invention can convert the rotary motor and the linear motor by changing the magnetic field, so as to realize the working requirements in different environments; by setting the change of the magnetic field inside the coil, And change the distribution of the magnetic field inside the entire motor, so that the motor can not only rot...

Abstract

The invention relates to a dual-functional motor capable of rotating and linearly moving. The motor comprises a casing arranged at the outermost part and end covers arranged at the two ends of the casing, bearings are fixed in the middles of the end covers, a support rotating shaft is arranged between the two bearings, two brackets are fixed at the outer part of the casing and used for supportingthe whole motor, and a plurality of stator blocks are uniformly embedded in the casing. A coil is wound on each stator block, a rotor core is fixed on the rotating shaft, and two rows of permanent magnets are embedded in radial symmetrical positions of an outer ring of the rotor core. According to the dual-functional motor capable of rotating and linearly moving designed by the invention, the rotating motor and the linear motor can be switched by changing a magnetic field, so that the working requirements in different environments are met; the motor can rotate normally and can also be converted into a linear single machine for linear motion, the conversion of double functions of the motor is achieved so as to adapt to different working environments, then the adaptation and the applicationof the motor are improved, and the practicability, the market application value and the market prospect of the motor are improved.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a dual-function motor that can rotate and move linearly. Background technique [0002] A motor refers to an electromagnetic device that converts or transmits electrical energy according to the law of electromagnetic induction, or converts one form of electrical energy into another form of electrical energy; a motor converts electrical energy into mechanical energy. [0003] In view of the changing working conditions and energy-saving requirements of automobiles, it is especially necessary for the motor to have multiple functions of electric power, power generation feedback and electromagnetic braking at the same time. And the braking process of the combination of power generation feedback and electromagnetic braking is similar to the braking process of the anti-lock braking system ABS and driving anti-slip control ASR in modern cars, that is, not only energy recovery is realized, ...
