Description
Technical field
The utility model belongs to generator or motor type, particularly a kind of series multistage type switched reluctance motor.
Background technology
Existing switched reluctance motor is one group of biconvex pole type stator rotor set, patent 03118502.9 switched reluctance motor for example, patent 200420018484.4 Hybrid Excitation Switched Reluctance Motor etc.Therefore, there is following defective:
1, pulsating torque is big
Because rotor is two salient pole type structures, can produce bigger torque, but also be accompanied by bigger pulsating torque.
2, need loop circuit control
Switched reluctance motor must go excitatory suitable phase sequence according to the angle of rotating shaft.
3, non-linear torque produces characteristic
Because the torque of switched reluctance motor and exciting curent square and self-induction are directly proportional to the rate of change product of rotor-position, and self-induction changes along with exciting curent again, so the torque of switched reluctance motor generation tool height non-linear nature.
4, running noise is big
Because the rotor of switched reluctance motor is two salient pole type structures, so can produce big noise in the running.In addition, the exciting curent of stator also can produce bigger noise in the running.
Shortcomings such as the purpose of this utility model is big in order to overcome the pulsating torque that has the switched reluctance motor existence now, needs loop circuit control, and non-linear torque generation characteristic and running noise are big provide a kind of series multistage type switched reluctance motor.
The technical solution of the utility model is: this series multistage type switched reluctance motor, comprise electric machine stand, end cap, rotation axis, bearing and biconvex pole type stator rotor set, the two ends of support are provided with end cap, bearing is flush-mounted in the center of end cap, rotation axis is assemblied in the support by bearing, the coaxial at least two group biconvex pole type stator rotor set that are installed in series on the described rotation axis, every group rotor progression is more than the two poles of the earth, axially leave the space between every group of biconvex pole type stator rotor set, and hold the coil of assembly on the magnetic pole of stator.
Magnetic pole between the stator of described every group of biconvex pole type stator rotor set arranges in stagger angle of radial direction, and this angle is 0 to spend arbitrarily angled in 360 degree.
Magnetic pole between the rotor of described every group of biconvex pole type stator rotor set arranges in stagger angle of radial direction, and this angle is 0 to spend arbitrarily angled in 360 degree.
Synchronous or the asynchronous control of the energising sequential of the coil windings of the magnetic pole of the stator of described every group of biconvex pole type stator rotor set.
The energising sequential homophase of the coil windings of the magnetic pole of the stator of described every group of biconvex pole type stator rotor set or anti-phase control.
Series multistage type switched reluctance motor of the present utility model is that the motor in prior art adopts on the basis of one group of biconvex pole type stator rotor set, the many groups of series connection biconvex pole type stator rotor set.Its advantage is as follows:
1, simple structure, low cost of manufacture
Aspect rotor, the rotor structure of series multistage type switched reluctance motor does not simply need expensive magnetic material and does not have the rotor winding.Aspect stator, stator adopts centralized winding, and handling ease is so can reduce the manufacturing cost of series multistage type switch-type reluctance motor.
2, the structure firm, can stand utmost point bad working environment
The rotor of series multistage type switched reluctance motor there is no winding and sticks together or inlay permanent magnetic material, so it is firm in structure and rotor is also non-carbonate or commutator segment, produces the problem of spark when therefore not having commutation, turns round so rotor can bear at a high speed and under the adverse circumstances.
3, running efficiency height
Because the torque of series multistage type switched reluctance motor system utilizes the magnetic resistance change rate principle to produce, so rotor do not have electric current, thus no copper loss of rotor, so efficient is than general induction machine height.
4, high torque (HT)/moment of inertia ratio
Because of rotor need not use winding, make the commentaries on classics inertia of its rotor little, so have high torque (HT)/moment of inertia ratio.
5, power converter is simple in structure
Owing to only need the exciting curent of single polarity,, can avoid the conducting simultaneously of the arm switch up and down problem of short-circuit of transducer so need not use the converter structure of full-bridge type.
6, has fault-tolerance
Because the every independent mutually excitatory running of the stator of series multistage type switched reluctance motor, even therefore wherein one break down mutually, motor also can remain in operation, so have suitable competitive advantage for the application scenario of the high fault-tolerant ability of needs.
7, pulsating torque is little
Owing to adopted many biconvexs pole type stator rotor set (more than two groups and two groups, every group rotor number of poles is more than the two poles of the earth) series connection structure, radially staggering an angle (more than two groups and two groups between stator or rotor simultaneously, every group rotor number of poles is more than the two poles of the earth) arrange, so promptly kept bigger torque, simultaneously reduce pulsating torque again, guaranteed the balance of rotating speed and the precision of speed governing.
8, reduce nonlinear torque and produced characteristic
Because the torque of switched reluctance motor and exciting curent square and self-induction are directly proportional to the rate of change product of rotor-position, and self-induction changes along with exciting curent again, but adopted many biconvexs pole type stator rotor set (more than two groups and two groups, every group rotor number of poles is more than the two poles of the earth) series connection structure, arrange in the angle that radially staggers (0 spend in 360 degree arbitrarily angled) between stator or rotor simultaneously, constant down in torque, owing to adopt series multistage type switched reluctance motor technology, exciting curent and self-induction have all reduced, so the torque of series multistage type switched reluctance motor produces less non-linear torque character.
9, running noise is little
Owing to adopt the running noise of the switched reluctance motor of original switched reluctance motor technology manufacturing mainly to produce in the running by the exciting curent of stator, but adopted many biconvexs pole type stator rotor set (more than two groups and two groups, every group rotor number of poles is more than the two poles of the earth) series connection structure, radially staggering an angle (more than two groups and two groups between stator or rotor simultaneously, every group rotor number of poles is more than the two poles of the earth) arrange, exciting curent has reduced, so running noise has also reduced.
