Abstract
The utility model relates to a mechanical secondary speed control variable speed permanent magnet motor which includes a rotor body, a main shaft, and a stator body which is corresponding to the rotor body. The motor also includes a sliding sleeve and pendulum bob connecting rods. The tail of the pendulum bob connecting rod is provided with a centrifugal inertia pendulum bob. The rotor body is fixed on the sliding sleeve of the main shaft. The rotor body can move on the axial direction of the main shaft along with an inertia body at a certain rotation speed, so the rotor body can partially move out of the corresponding stator body to change an original loop inductive reactance, and consequently the secondary speed control is realized. The tail of the main shaft is fixed with a connecting rod support. The pendulum bob connecting rods are fixed on the connecting rod support via pins. The front end of the pendulum bob connecting rod contacts with the sliding sleeve. The permanent magnet motor can satisfy the torque and the rotating speed requirements at the same time, and has the characteristics of simple structure and excellent speed regulation performance.
Description
Technical field
The utility model relates to a kind of mechanical secondary speed control variable speed permanent magnetism motor.
Background technology
Along with the development of permanent magnetic material and power electronic technology, the frequency control motor permanent magnetism velocity modulation electric engine has been widely used in all trades and professions such as new-energy automobile.Prior motor will be considered torque and rotating speed when selecting parameter; Because new-energy automobile needs bigger torque and power when restarting, select than satisfy behind the heavy-duty motor moment of torsion to be difficult to satisfy simultaneously the rotating speed requirement again, must improve operating voltage and satisfy; Can increase cost and weight; Another kind of scheme selects for use high-speed electric expreess locomotive to add transmission system, because the transmission system efficiency losses is big, is not long-range selection.Therefore, need a kind of motor that can satisfy moment of torsion and rotating speed requirement simultaneously.
The utility model content
The utility model technical problem to be solved provides a kind of mechanical secondary speed control variable speed permanent magnetism motor; This electric machine structure is simple and reliable; Can when low speed, provide original motor high moment of torsion output; Further improve the rotating speed of original motor behind the mechanical speed change, to overcome the above-mentioned deficiency that exists in the prior art.
The technical scheme that the utility model solves the problems of the technologies described above is following:
A kind of mechanical secondary speed control variable speed permanent magnetism motor comprises that rotor block, main shaft reach and the corresponding stator body of said rotor block, also comprise sliding sleeve and pendulum connecting rod.Said rotor block is fixed on the main shaft through sliding sleeve, and said rotor block can move axially along this main shaft.Said main shaft afterbody is fixed with connecting rod support, and said pendulum connecting rod is fixed on the connecting rod support through bearing pin, and the front end of pendulum connecting rod contacts with said sliding sleeve, and the tail end of pendulum connecting rod is provided with coasting body.
Further, described coasting body is centrifugal inertia pendulum.
The described magneto of the utility model has characteristics simple and reliable for structure, good speed adjustment features; Rotor block can main shaft moves axially in certain rotating speed lower edge with coasting body, makes rotor block partly shift out corresponding stator body and changes original loop induction reactance and realize the secondary speed control purpose.
Description of drawings
Fig. 1 is the structural representation of the described magneto of the utility model;
In the accompanying drawing, the list of parts of each label representative is following:
1, rotor block, 2, main shaft, 3, stator body, 4, sliding sleeve, 5, the pendulum connecting rod, 6, connecting rod support, 7, coasting body, 8, bearing pin.
Embodiment
Below in conjunction with accompanying drawing the principle and the characteristic of the utility model are described, institute gives an actual example and only is used to explain the utility model, is not the scope that is used to limit the utility model.
As shown in Figure 1, the described mechanical secondary speed control variable speed permanent magnetism motor of the utility model embodiment, comprise rotor block 1, main shaft 2, with the stator body 3 of said rotor block 1 corresponding connection, be slidingly mounted on sliding sleeve 4 and pendulum connecting rod 5 on the main shaft 2.Said rotor block 1 is fixed on the main shaft 2 through sliding sleeve 4; Said main shaft 2 afterbodys are fixed with connecting rod support 6; Said two pendulum connecting rods 5 all are fixed on the connecting rod support through bearing pin 8, and the front end of pendulum connecting rod 5 contacts with said sliding sleeve 4, and the tail end of pendulum connecting rod 5 is provided with coasting body 7.Said rotor block 1 can main shaft 2 moves axially in certain rotating speed lower edge with coasting body.When rotor block 1 moves, because driving said pendulum connecting rod 5, moves the centrifugal action of coasting body 7 at sliding sleeve 4 places, make rotor block 1 part shift out corresponding stator body 3 and change original loop induction reactance and realize the secondary speed control purpose.
Described coasting body is centrifugal inertia pendulum.
The above is merely the preferred embodiment of the utility model, and is in order to restriction the utility model, not all within the spirit and principle of the utility model, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection range of the utility model.
