Description
Technical field
The invention belongs to and relate to double salient-pole electric machine technical field, relate in particular to a kind of segmented-rotor double salient-pole electric machine of novel laminating structure.
Background technology
Double salient-pole electric machine taking electric excitation winding as excitation source has increased magnet exciting coil in stator teeth groove at present, makes motor be converted to electric field switch reluctance motor by the switched reluctance machines that becomes magnetic resistance.Motor has kept sound state speed governing that traditional direct current machine is good, reliable and be easy to the features such as controls, and its speed-regulating range width, has avoided general motor to produce torque by current－carrying conductor Interaction Force like that, but by the magnetic pull generation between rotor.Adopt biconvex to hit structure for general electric excitation biconvex electrode stator, be parallel teeth by three adjacent stators teeth of rational teeth groove design, after being divided into four groups there are eight sulculuses of four vats in stator punching, in vat, embed two armature winding and two excitation winding, in sulculus, embed two armature winding, can ensure certain copper factor and same end height.The half that segmented-rotor electric excitation biconvex electrode electric machine is original because armature tooth is reduced to, ensure that the large and excitation winding internal resistance of exciting watts that certain output end voltage needs is less than 1 Ω, cause the large and wire diameter of the excitation winding number of turn of needs slightly and then cause that copper factor is high and end height is inconsistent; Electric excitation biconvex electrode electric machine is because 12 armature coils are distributed on 12 straight-tooth simultaneously, each magnet exciting coil is across three armature tooths, 4 magnet exciting coils are distributed on stator, in the time that magnet exciting coil is switched on, the magnetic line of force of generation, through air gap, passes air gap again by rotor, enter armature pole and form closed-loop path, but the rotor mechanical angle that now magnetic flux path is crossed over is 90 °, can not ensure magnetic resistance minimum, is unfavorable for the raising of power density.
Summary of the invention
The object of this invention is to provide one and can ensure that the each teeth groove copper factor of stator punching is consistent and end height is consistent; Improve the segmented-rotor double salient-pole electric machine of the novel laminating structure of power density simultaneously.The problem that will solve required for the present invention realizes by the following technical solutions: a kind of segmented-rotor double salient-pole electric machine of novel laminating structure, comprise stator, the rotor fan type utmost point and every magnetic lining, stator has 12 teeth, rotor has eight fan type utmost points to be embedded on magnetic lining, the stator punching of described stator is provided with six field pole grooves and is distributed with six armature pole grooves at interval of a field pole groove, in field pole groove, be provided with magnet exciting coil, in armature pole groove, be provided with armature coil, isolated with insulating barrier between armature coil and magnet exciting coil.Described armature coil area and magnet exciting coil Area Ratio to be 27:37 identical with excitation total number of turns Area Ratio with the armature total number of turns area of actual design in single groove and armature winding and excitation winding end height consistent.
The said structure that the present invention adopts can ensure that the copper factor of motor stator punching teeth groove is consistent, armature winding is consistent with excitation winding end height, is conducive to improve copper factor, dwindles motor axial dimension, avoid coil to be subject to electromagnetic force in punching groove and vibrate, ensureing motor security of operation; Said structure has shortened magnetic flux path simultaneously, can ensure magnetic resistance minimum, reduces ferromagnetic loss; Increase winding flux change rate simultaneously and improve electromagnetism torsion, improved power density.
