Description
Technical field
The utility model genus relates to the double salient-pole electric machine technical field, relates in particular to a kind of segmented-rotor double salient-pole electric machine of novel laminating structure.
Background technology
Double salient-pole electric machine take electric excitation winding as excitation source, increased magnet exciting coil in the 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 the good sound attitude speed governing of traditional direct current machine, reliable and be easy to the characteristics such as controls, and its speed-regulating range width has avoided general motor to produce torque by the current－carrying conductor Interaction Force like that, but by the generation of the magnetic pull 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, eight sulculuses of four vats appear in stator punching, embed two armature winding and two excitation winding in vat, embed two armature winding in sulculus, can guarantee certain copper factor and same end height.Half that the segmented-rotor electric excitation biconvex electrode electric machine is original because armature tooth is reduced to, guarantee the large and excitation winding internal resistance of exciting watts that certain output end voltage needs 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, when magnet exciting coil was switched on, the magnetic line of force of generation passed air gap, again passed air gap by rotor, enter armature pole and form the closed-loop path, but the rotor mechanical angle that this moment, magnetic flux path was crossed over is 90 °, can not guarantee that magnetic resistance is minimum, is unfavorable for the raising of power density.
Summary of the invention
The purpose of this utility model is to provide and a kind ofly can guarantees that each teeth groove copper factor of stator punching is consistent and end height is consistent; Improve simultaneously the segmented-rotor double salient-pole electric machine of the novel laminating structure of power density.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 the magnetic lining, stator has 12 teeth, rotor has eight fan type utmost points to be embedded on the 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, be provided with magnet exciting coil in the field pole groove, be provided with armature coil in the armature pole groove, isolated with insulating barrier between armature coil and magnet exciting coil.Described armature coil area and magnet exciting coil Area Ratio be 27:37 with single groove in the armature total number of turns area of actual design and armature winding identical with excitation total number of turns Area Ratio and the excitation winding end height consistent.
The said structure that the utility model adopts can guarantee that the copper factor of motor stator punching teeth groove is consistent, armature winding is consistent with the excitation winding end height, be conducive to improve copper factor, dwindle the motor axial dimension, avoid coil to be subjected to electromagnetic force in the punching groove and vibrate, guaranteeing the motor security of operation; Said structure has shortened magnetic flux path simultaneously, can guarantee that magnetic resistance is minimum, reduces ferromagnetic loss; Increase simultaneously winding flux change rate and improve electromagnetism torsion, improved power density.
