Abstract
The invention discloses a double-salient pole motor with a novel laminating structure. The double-salient pole motor comprises a stator (1) and a rotor (2), wherein the stator (1) has twelve poles, and the rotor (2) has eight poles; a stator lamination is provided with eight small grooves and four large grooves distributed at intervals of every two small grooves, an armature coil (4) is arranged in the small grooves respectively, an armature coil (4) and a magnet exciting coil (3) are arranged in the large grooves in upper and lower layers respectively, an insulating layer (5) is arranged between the armature coil (4) and the magnet exciting coil (3), and the armature coil (4) in the small groove and the armature coil (4) in the large groove have the same area. By adopting the structure, the double-salient pole motor can ensure consistent space factors of laminating tooth grooves of the motor stator, is favorable for improving the space factor, and prevents the coils from vibrating in the laminating grooves under the action of electromagnetic force so as to ensure the safe operation of the motor.
Description
Technical field
The present invention relates to a kind of double salient-pole electric machine, relate in particular to a kind of double salient-pole electric machine with novel laminating structure.
Background technology
Talk about publicly knownly, the planform that mainly is meant such motor stator and rotor punching of gaining the name of double salient-pole electric machine is the biconvex polar form, and switched reluctance machines is a kind of canonical form of double salient-pole electric machine.It is the double salient-pole electric machine of excitation source with electric excitation winding that Nanjing Aero-Space University in 1998 has designed a kind of on the basis of switched reluctance machines, this kind motor has increased magnet exciting coil in the stator teeth groove, make motor be converted to electric field switch reluctance motor by the switched reluctance machines that becomes magnetic resistance.This motor has kept the good sound attitude speed governing of traditional direct current machine, reliable and be easy to characteristics such as control, and its speed adjustable range is big, produces torque by current interphase interaction power like that unlike general motor, but passes through the magnetic pull generation between the rotor.For general switched reluctance machines, stator punching adopts the biconvex electrode structure, and coil is embedded in the teeth groove of punching, makes to guarantee certain tankful rate.Electric excitation biconvex electrode electric machine is because many magnet exciting coils, when the coil rule, causes the punching teeth groove that has loose, and the punching teeth groove compactness that has can not guarantee the copper factor unanimity of each teeth groove to be unfavorable for the raising of copper factor.
Summary of the invention
The purpose of this invention is to provide a kind of double salient-pole electric machine with novel laminating structure that can guarantee each teeth groove copper factor unanimity of stator punching.
The problem that will solve required for the present invention realizes by the following technical solutions: it comprises stator and rotor, stator has 12 utmost points, rotor has eight utmost points, described stator punching is provided with four vats of eight sulculuses and the distribution of every next but two sulculus, establish an armature coil in each sulculus respectively, in each vat with up and down two layers establish an armature coil and a magnet exciting coil respectively, be provided with insulating barrier between armature coil and the magnet exciting coil, the armature coil in the sulculus is identical with armature coil area in the vat.
The said structure that the present invention adopts can guarantee the copper factor unanimity of motor stator punching teeth groove to help improving copper factor, avoids coil to be subjected to the electromagnetic force effect in the punching groove and vibrates, and guarantees the motor security of operation; Also can increase the yoke portion area of stator punching, thereby improve electric efficiency.
Description of drawings
The present invention is described further below in conjunction with accompanying drawing:
Accompanying drawing is depicted as structural representation of the present invention
Embodiment
By accompanying drawing as can be known, this double salient-pole electric machine with novel laminating structure comprises stator 1 and rotor 2, stator 1 has 12 utmost points, rotor 2 has eight utmost points, described stator punching is provided with four vats of eight sulculuses and the distribution of every next but two sulculus, embed an armature coil 4 in each sulculus respectively, in each vat with up and down two layers embed an armature coil 4 and a magnet exciting coil 3 respectively, isolated between armature coil 4 and the magnet exciting coil 3 with insulating barrier 5, insulating barrier is made with insulating material, and the armature coil 4 in the sulculus is identical with armature coil 4 areas in the vat.The present invention makes the copper factor of four grooves that embed magnet exciting coil and armature coil consistent, and remaining eight copper factor unanimities that embed armature coil have also increased stator punching yoke portion area simultaneously.The present invention's electricity consumption excitation in motor substitutes permanent-magnet structure, regulates motor-field intensity by regulating the magnet exciting coil size of current, control motor torque size.
