Description
Technical field
The present invention relates to a kind of mechanical secondary speed control variable speed permanent magnetism motor.
Background technology
Along with the development of permanent-magnet material and Power Electronic Technique, frequency control motor permanent magnetism velocity modulation electric engine has been widely used in all trades and professions such as new-energy automobile. Existing motor will be considered torque and rotational speed in the time selecting parameter, while restarting due to new-energy automobile, need larger torque and power, after selection relatively high power motor, meet moment of torsion and be difficult to meet again rotating speed requirement simultaneously, must improve operating voltage meets, can increase cost and weight, another kind of scheme selects high-speed electric expreess locomotive to add transmission system, because transmission system efficiency losses is large, is not long-range selection. Therefore, need a kind of motor that can simultaneously meet moment of torsion and rotating speed requirement.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of mechanical secondary speed control variable speed permanent magnetism motor, this electric machine structure is simple and reliable, can in the time of low speed, provide original motor high moment of torsion output, after mechanical speed change, further improve the rotating speed of original motor, to overcome above shortcomings in prior art.
The technical scheme that the present invention solves the problems of the technologies described above is as follows:
A kind of mechanical secondary speed control variable speed permanent magnetism motor, comprises rotor block, main shaft and the stator body corresponding with described rotor block, also comprises sliding sleeve and pendulum connecting rod. Described rotor block is fixed on main shaft by sliding sleeve, and described rotor block can move axially along this main shaft. Described main shaft tail is fixed with connecting rod support, and described pendulum connecting rod is fixed on connecting rod support by bearing pin, and the front end of pendulum connecting rod contacts with described sliding sleeve, and the tail end of pendulum connecting rod is provided with coasting body.
Further, described coasting body is centrifugal inertia pendulum.
Feature simple and reliable for structure, good speed adjustment features that magneto of the present invention has, rotor block can move axially along main shaft with coasting body under certain rotating speed, makes rotor block part shift out corresponding stator body and changes original loop induction reactance and realize secondary speed control object.
Brief description of the drawings
Fig. 1 is the structural representation of magneto of the present invention;
In accompanying drawing, the list of parts of each label representative is as follows:
1, rotor block, 2, main shaft, 3, stator body, 4, sliding sleeve, 5, pendulum connecting rod, 6, connecting rod support, 7, coasting body, 8, bearing pin.
Detailed description of the invention
Below in conjunction with accompanying drawing, principle of the present invention and feature are described, example, only for explaining the present invention, is not intended to limit scope of the present invention.
As shown in Figure 1, the mechanical secondary speed control variable speed permanent magnetism motor described in the embodiment of the present invention, comprise rotor block 1, main shaft 2, with the stator body 3 of described rotor block 1 corresponding connection, be slidably mounted on sliding sleeve 4 and pendulum connecting rod 5 on main shaft 2. Described rotor block 1 is fixed on main shaft 2 by sliding sleeve 4, described main shaft 2 afterbodys are fixed with connecting rod support 6, described two pendulum connecting rods 5 are all fixed on connecting rod support by bearing pin 8, and the front end of pendulum connecting rod 5 contacts with described sliding sleeve 4, and the tail end of pendulum connecting rod 5 is provided with coasting body 7. Described rotor block 1 can move axially along main shaft 2 with coasting body under certain rotating speed. In the time that rotor block 1 moves, because driving described pendulum connecting rod 5, moves at sliding sleeve 4 places the centrifugal action of coasting body 7, and make rotor block 1 part shift out corresponding stator body 3 and change original loop induction reactance and realize secondary speed control object.
Described coasting body is centrifugal inertia pendulum.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
