The cracked polar type synchronous machine comprises rotor and stator component, and described rotor and described stator apparatus are in a described motor housing.Described stator comprises a shaped framework coil and described shaped framework coil is peripheral and the iron-core coil of skeleton inner chamber; Described shaped framework coil is called stator coil again; Described rotor is that the magnet steel of permanent magnetic material making and the rotor core of described magnet steel periphery constitute by permanent magnet.The iron-core coil of existing cracked polar type synchronous machine and rotor core constitute a synchronous electric machine iron core, and are shaped by the punching of the steel plate of uniform thickness, as shown in Figure 3.

Described shaped framework coil be stator coil after energising, described rotor core just produces the armature rotating magnetic field, for described rotor output torque, described rotary speed of rotator is a synchronous speed.The size of described rotor output torque is decided by the magnetic field intensity of described armature rotating magnetic field and the described rotor of being made by permanent magnetic material.

Thereby, existing cracked polar type synchronous machine under described rotor and described stator structure and overall dimension and the constant prerequisite of material properties thereof, the output torque that can't increase described motor.

Summary of the invention

Purpose of the present invention is exactly in order to overcome above-mentioned weak point of the prior art, provide a kind of under synchronous machine structure and overall dimension and the constant prerequisite of material properties thereof, adopt partial thickening electric machine iron core thickness to increase the synchronous machine iron core of synchronous machine output torque.

The objective of the invention is to have by providing a kind of that following synchronous machine iron core realizes, described synchronous machine is made up of rotor and stator, described rotor and described stator apparatus are in a shell, and described stator comprises a shaped framework coil and is arranged on the peripheral iron-core coil with the skeleton inner chamber of described shaped framework coil.Described rotor comprises a magnet steel and the rotor core that is arranged on described magnet steel periphery.The rotor core gap of the setting of described rotor core.

One end of described shaped framework coil is connected with lead, and described iron-core coil and described rotor core constitute holistic described synchronous machine iron core.

Described rotor core is set to rotor and thickens iron core.

Described rotor core is to thicken the described rotor that is connected with an enhancing torque sheet to thicken iron core.

Described shaped framework coil be stator coil after energising, described rotor core just produces the armature rotating magnetic field, for described rotor output torque.

It is that described motor output torque has not had obvious enhancing than thickening the motor output torque that connects described enhancing moment iron core that the present invention is applied to cracked polar type synchronous machine result.

Compared with prior art, the invention has the advantages that: 1. motor output torque has strengthened 40 percent under all constant prerequisite of the parameter of electric machine structure, overall dimensions and shaped framework coil; 2. expansion range of application, the alternative supporting middle Lundell synchronous motor of timer that is applied to household electrical appliance such as microwave oven, electric pressure, thus can reduce the supporting cost of above-mentioned household electrical appliance greatly.

Embodiment

Below in conjunction with accompanying drawing embodiment invention is described in further detail.

Fig. 1, Fig. 2 show the execution mode that a kind of synchronous machine iron core of the present invention is applied to the cracked polar type synchronous machine.Synchronous machine comprises rotor 1 and stator 2 parts.Described rotor 1 installs in a motor housing (not shown) with described stator 2.Stator 2 comprises a shaped framework coil 21 and the iron-core coil of being made up of peripheral iron core of described shaped framework coil and skeleton inner chamber iron core 23 22; Be that iron-core coil comprises a peripheral iron core of a shaped framework coil and a skeleton inner chamber iron core 23, referring to shown in Figure 2.

Described shaped framework coil 21 is called stator coil again; Described rotor 1 comprises that one is that the magnet steel 11 made of permanent magnetic material and the rotor core 12 of described magnet steel periphery constitute by permanent magnet.Rotor core 12 is provided with gap 5; One end of shaped framework coil 21 is connected with lead 6.

Described rotor core is set to rotor and thickens iron core 4.Described rotor core is to thicken the described rotor that is connected with an enhancing torque sheet 41 to thicken iron core 4.Be that synchronous machine iron core 3 of the present invention is to thicken iron core 4 by iron-core coil 22, skeleton inner chamber iron core 23 with rotor to constitute, and rotor thicken iron core 4 and iron-core coil 22, skeleton inner chamber iron core 23 are made by same material.

Enhancing torque sheet 41 is provided with rotor core gap 5 rotors corresponding, consistent size and thickens iron core gap 9.

The thickness that rotor thickens iron core 4 is the gauge that is equal to or greater than magnet steel 11.

Rotor thickens and adopts riveted joint to thicken between iron core 4 and the belt coil iron core 22 to be connected; Or adopt welding to thicken connection; Or adopt fastening to thicken connection.

One end lead 6 of shaped framework coil 21 is after energising, and rotor thickens iron core 4 and just produces the armature rotating magnetic field, for rotor output torque.

Rotor core 12 thickness of the present invention are 2 millimeters, and enhancing torque sheet 41 thickness that thicken connection are 1 millimeter, and then to thicken the thickness of iron core 4 be 3 millimeters to rotor; Being applied to cracked polar type synchronous machine result is: motor output torque never thicken connection 2.5 the gram * centimetre be strengthened to thicken connection 3.5 the gram * centimetre; Be that motor output torque has strengthened 40 percent than originally.And the enhancing of above-mentioned motor output torque is to be issued in all constant prerequisite of the parameter of described electric machine structure, overall dimensions and shaped framework coil and skeleton inner chamber.Thereby, the cracked polar type synchronous machine that is applied to a kind of synchronous machine iron core of the present invention can enlarge range of application widely, be its alternative supporting Lundell synchronous motor of timer that is widely used in household electrical appliance such as microwave oven, electric pressure, thereby can reduce the supporting cost of above-mentioned household electrical appliance timer greatly.
