Abstract
The utility model relates to a multi-phase lateral magnetic field switch reluctance motor, which adopts the combined type multipole structure, namely, a concave stator punching and a rectangular rotor punching with one specification. A combined stator coil is formed in a ring shape and is inlaid in the concave stator punching, and therefore, the grade motor with different poles, different phases, and various powers can be combined arbitrarily.
Description
The heterogeneous transverse magnetic switched reluctance machines of the utility model belongs to technical field of motors.
Existing switched reluctance machines, its stator, rotor is salient pole type.Have only stator that coil is arranged, rotor does not have coil.It structurally can not be arbitrarily made with the various power grade motors of different numbers of poles, the different numbers of phases.To the greatest extent let it be rated output power is bigger than the induction machine of same size, it is also easier, economical and can keep high-efficiency operation in the rotor speed scope than broad to drive electronic circuit.But also there is defective in it in the dragging system of low speed high torque and wide range speed control.
Heterogeneous transverse magnetic switched reluctance machines of the present utility model not only has the advantage of above-mentioned motor.And structurally adopt the composite type multi-polar structure.Be the various power grade motors that a kind of stator, rotor punching of specification can be arbitrarily made with different numbers of poles, the different numbers of phases.Even under low-down rotating speed, also can turn round reposefully, and noise is very little, be specially adapted to the dragging system of low speed high torque and wide range speed control.
The purpose of this utility model is to adopt the composite type multi-polar structure, reduces the cost in the process of producing product widely.And can improve electric efficiency and save the energy.Make this motor have market competitiveness and economy.
The heterogeneous transverse magnetic switched reluctance machines of the utility model illustrates its design feature with four phases, ten ends of the earth motors.Illustrated in figures 1 and 2 is the radial and axial schematic diagram of four phases, ten ends of the earth motors.Stator 1, rotor 2 and rotating shaft 3 among the figure.One phase stator radially builds up multi-polar structure by the concave shape punching, rotor then by the rectangular punching of rectangle radially closed assembly form.When four phase stator units were installed in segmentation vertically, every phase stator must turn over 5 °, turned over 20 ° of polar moments with rotor after guaranteeing one week of four phase stators energising.Stator coil is a garden ring, is embedded in the stator slot of concave shape multi-polar structure.Fig. 1 has also shown and has comprised radial and axial magnetic flux path.180 ° of electrical degrees of each conducting of every phase coil, each differs 90 ° of electrical degrees interdependent time, and this shows in each moment all has the work of two-phase coil electricity.Torque is had by magnetic circuit selects the trend of minimum reluctance structure to produce.Promptly make rotor pole forward the stator poles positions aligning to, and make the inductance maximum.Because generation of torque and coil electricity orientation independent.Therefore can adopt unidirectional DC power supply, driver circuit is oversimplified, drive unit is also more economical.
Coil is switched in 0～π scope, rotor produces on the occasion of torque, and produces the negative value torque in π～2 π scopes.Therefore control running of motor forward or antiport also easily, simply.
According to different application scenarios, heterogeneous transverse magnetic switched reluctance machines has three kinds of different structural shapes.Promptly first kind is internal rotor, outer stator structure, and second kind is external rotor, internal stator structure; The third is interior external stator, cup type rotor structure.The motor of this structure can accomplish to exceed the nearly one times power density of conventional motor.
In sum, heterogeneous its characteristics of transverse magnetic switched reluctance machines are: the first, have concave shape stator punching and rectangle rotor punching.The second, knockdown stator and rotor structure, promptly a kind of stator of specification, rotor punching can at random be combined into different numbers of poles, the various power of the different numbers of phases wait utmost point motor.Three, stator coil is annular shape, is embedded in the multipole stator slot that the font stator punching constituted.
