Abstract
The utility model discloses a kind of synchronous reluctance permanent magnetic motors rotor structures, including permanent magnet, salient pole, punching closed slot, magnetic slot, rotor and shell, the case inside is provided with punching closed slot, magnetic slot is set between the punching closed slot, is provided in the shell in rotor and rotor and is provided with permanent magnet.Permanent magnet is put into rotor by the utility model, salient pole is increased in the axis direction of rotor, it is the better difference for increasing d axle inductance and q axle inductance that it, which is acted on, to more effectively improve magnetic resistance of motor torque, the power density of motor can be made higher, the volume of motor is reduced, and starting performance is more preferable, is suitble to be widely popularized and used.
Description
Technical field
The utility model relates to electric machine structure technical field, in particular to a kind of synchronous reluctance permanent magnetic motors rotor structure.
Background technique
Permanent magnet synchronous motor installs permanent magnet on rotor, and structure is uniformly to be distributed in the outside of rotor, synchronous reluctance
Rotor is distribution closed slot, does not have to installation permanent magnet, causes the power density of its motor lower, and the volume of motor is larger,
Starting performance is bad, for this purpose, it is proposed that a kind of synchronous reluctance permanent magnetic motors rotor structure.
Utility model content
The main purpose of the utility model is to provide a kind of synchronous reluctance permanent magnetic motors rotor structure, by by permanent magnet
It is put into rotor, increases salient pole in the axis direction of rotor, effect is the better difference for increasing d axle inductance and q axle inductance, from
And magnetic resistance of motor torque is more effectively improved, the power density of motor can be made higher, the volume of motor is reduced, and starting performance is more
It is good, it can effectively solve the problems in background technique.
To achieve the above object, the technical solution that the utility model is taken are as follows:
A kind of synchronous reluctance permanent magnetic motors rotor structure, including permanent magnet, salient pole, punching closed slot, magnetic slot, rotor and
Shell, the case inside are provided with punching closed slot, and magnetic slot, setting in the shell are arranged between the punching closed slot
Have in rotor and rotor and is provided with permanent magnet.
Further, salient pole is provided on the outside of the rotor and salient pole is located at the axis direction of rotor.
Further, the quantity of the punching closed slot and magnetic slot is multiple, and punching closed slot and magnetic slot exist
Case inside is symmetrically arranged.
Compared with prior art, the utility model has the following beneficial effects: permanent magnet is put into rotor by the utility model,
Salient pole is increased in the axis direction of rotor, effect is the better difference for increasing d axle inductance and q axle inductance, thus more effectively
Raising magnetic resistance of motor torque, the power density of motor can be made higher, the volume of motor is reduced, and starting performance is more preferable.
Detailed description of the invention
Fig. 1 is a kind of sectional view of synchronous reluctance permanent magnetic motors rotor structure of the utility model.
In figure: 1, permanent magnet；2, salient pole；3, punching closed slot；4, magnetic slot；5, rotor；6, shell.
Specific embodiment
To be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, below
In conjunction with specific embodiment, the utility model is further described.
As shown in Figure 1, a kind of synchronous reluctance permanent magnetic motors rotor structure, including permanent magnet 1, salient pole 2, punching closed slot 3,
Magnetic slot 4, rotor 5 and shell 6 are provided with punching closed slot 3 on the inside of the shell 6, magnetic are arranged between the punching closed slot 3
Steel tank 4 is provided in rotor 5 and rotor 5 in the shell 6 and is provided with permanent magnet 1.
Wherein, it is provided with salient pole 2 on the outside of the rotor 5 and salient pole 2 is located at the axis direction of rotor 5.
As shown in Figure 1, salient pole 2 can preferably increase the difference of d axle inductance and q axle inductance, thus more in the present embodiment
It is effective to improve magnetic resistance of motor torque.
Wherein, the quantity of the punching closed slot 3 and magnetic slot 4 is multiple, and punching closed slot 3 and magnetic slot 4 exist
It is symmetrically arranged on the inside of shell 6.
It should be noted that the utility model is a kind of synchronous reluctance permanent magnetic motors rotor structure, when work, by permanent magnet
1 is put into rotor 5, increases salient pole 2 in the axis direction of rotor 5, effect is the better difference for increasing d axle inductance and q axle inductance
Value can make the power density of motor higher to more effectively improve magnetic resistance of motor torque, and the volume of motor is reduced, starting
Performance is more preferable.
