Abstract
The utility model relates to a salient pole solid magnetic pole. The salient pole solid magnetic pole comprises a solid pole shoe, a high-strength fastening bolt, a solid pole body, a magnetic pole coil, an insulating washer, a pole body insulator, and a pi-shaped spring washer, wherein the pi-shaped spring washer is arranged between the magnetic pole coil and the solid pole body. Due to the fact that the pi-shaped spring washer is additionally arranged between the magnetic pole coil and the solid pole body, compaction of the magnetic pole coil is achieved through upward elastic force generated when the pi-shaped spring washer is compacted. Therefore, no gap needs to be reserved between the upper plane of the solid pole body and the solid pole shoe. The salient pole solid magnetic pole is easy to assemble, and meanwhile an induced current generated when a salient pole solid magnetic pole synchronous motor is started cannot damage the high-strength fastening bolt. Besides, operation of the salient pole solid magnetic pole synchronous motor is reliable. The utility model further relates to the salient pole solid magnetic pole synchronous motor comprising the salient pole solid magnetic pole.
Description
Technical field
The utility model relates to a kind of salient pole solid magnetic pole and salient pole solid magnetic pole synchronous machine.
Background technology
Tradition salient pole solid magnetic pole synchronous machine magnetic pole is mainly by solid pole shoe, the high strength fastening bolt, solid pole body, pole coil, insulating washer, pole(cell) insulation is formed, the structure of magnetic pole is: solid pole body peripheral side is wrapped up with pole(cell) insulation, dress pole body bottom insulating washer, the dress pole coil, dress pole body top insulating washer, adorn solid pole shoe, tighten the high strength fastening bolt at last, for pole coil is compressed, must between the lower plane of plane on the solid pole body and solid pole shoe, keep 0.1 ~ 0.2mm gap, this gap size must strictly be controlled, otherwise can influence rotor magnetic circuit, need the high professional qualification operating personnel to spend long time in order to control this gap size, salient pole solid magnetic pole synchronous machine magnetic pole efficiency of assembling is low like this, increased production cost, during simultaneously owing to salient pole solid magnetic pole synchronous motor starting, in solid pole shoe and solid pole body, can produce very big induced current, when having the gap, this gap has intercepted faradic passage, induced current can only pass through from the high strength fastening bolt, the induced current of high current density makes the bolt heating softening, damages the high strength fastening bolt, produces serious quality accident.
The utility model content
The purpose of this utility model is to overcome above defective, first purpose of the present utility model is, provide a kind of last plane of solid pole body and solid pole shoe salient pole solid magnetic pole very close to each other, second purpose of the present utility model provides a kind of salient pole solid magnetic pole synchronous machine that comprises this salient pole solid magnetic pole.
In order to realize first purpose, the utility model provides a kind of salient pole solid magnetic pole: it comprises solid pole shoe, high strength fastening bolt, solid pole body, pole coil, insulating washer, pole(cell) insulation, also comprise π shape spring washer, described π shape spring washer is located between coil and the solid pole body.
In order better π shape spring washer to be located, be provided with rectangular channel at described solid pole body and the contacted position of coil, the lower position of the position of described rectangular channel and π shape spring washer is complementary, the bottom of π shape spring washer places rectangular channel, on the contact-making surface that washer portion is placed in solid pole body contacts on π shape spring washer top.
In order to realize second purpose, the utility model also provides a kind of salient pole solid magnetic pole synchronous machine, and it comprises the salient pole solid magnetic pole, and described salient pole solid magnetic pole is above-mentioned salient pole solid magnetic pole.
Effect of the present utility model is: owing to have additional π shape spring washer between coil and solid pole body, reach compressing of coil by compressing π shape spring washer generation elastic force upwards, thereby between plane on the solid pole body and solid pole shoe, no longer need to leave the gap.Not only assembling is simple, and the induced current that produces during this salient pole solid magnetic pole synchronous motor startup can not damage high-strength bolt, and is reliable.
Description of drawings
Fig. 1, Fig. 2 are structural representation of the present utility model.
Embodiment
It comprises solid pole shoe 1, high strength fastening bolt 2, solid pole body 3, pole coil 4, insulating washer 5, pole(cell) insulation 6, also comprises π shape spring washer 7, and π shape spring washer 7 is located between coil 4 and the solid pole body 3.In order better π shape spring washer 7 to be located, be provided with rectangular channel at solid pole body 3 with pole coil 4 contacted positions, the lower position of the position of rectangular channel and π shape spring washer 7 is complementary, make the bottom of π shape spring washer 7 place rectangular channel, on the contact-making surface that the washer portion on π shape spring washer 7 tops is placed in solid pole body 3 contacts.
Because the magnetic pole of novel salient pole solid magnetic pole synchronous machine is flexible structure, angle diminishes and produces elastic force upwards when the spring leaf of π shape spring washer 7 compresses, high strength fastening bolt 2 is tightened back π shape spring washer 7 and is produced the pretightning force that gravity that elastic force upwards equals pole coil 4 adds pole coil 4, thereby make pole coil 4 fastening firm, can also increase work efficiency greatly, owing to do not have the gap between solid pole shoe 1 and the solid pole body 3, induced current is through contact-making surface between solid pole shoe 1 and the solid pole body 3 during salient pole solid magnetic pole synchronous motor starting, and the high strength fastening bolt 2 of needn't flowing through, thereby can not damage high strength fastening bolt 2, the reliability height of novel salient pole solid magnetic pole synchronous machine.
The utility model also provides a kind of salient pole solid magnetic pole synchronous machine, and it comprises the salient pole solid magnetic pole, and described salient pole solid magnetic pole is above-mentioned salient pole solid magnetic pole.Because above-mentioned salient pole solid magnetic pole has above-mentioned technique effect, the salient pole solid magnetic pole synchronous machine with this salient pole solid magnetic pole also should possess corresponding technique effect, introduces no longer in detail at this.
