Description
Technical field: the present invention relates to a kind of forced air cooling high thrust flat three-phase linear asynchronous motor.
Background technology: high thrust flat type linear electric motors are because employing is natural air cooled, and ventilation effect is poor at present, and volume is big, can not satisfy the needs of industry-by-industry.High thrust linear electric motors power is big, and the caloric value height is considered heat dissipation problem and performance issue, and motor volume is wanted corresponding increase.But be subjected to the restriction of environment for use, cube is little again.For solving above-mentioned contradiction, the cooling of ventilating becomes the key issue of design of electrical motor.
Patent Office of the State Intellectual Property Office patent No. " 02210740.1 " discloses a kind of flat three-phase linear asynchronous motor, these linear electric motors by elementary iron core, primary coil form elementary, elementary iron core is to be pressed by two kinds of silicon steel sheet snap-fasteners that yoke portion differs in length to constitute, and the high-temperature insulation bond layer is arranged between the silicon steel sheet.Prior art is natural air cooled, and under identical thrust, volume is big.
Summary of the invention: the purpose of this invention is to provide a kind of forced air cooling, high thrust, volume is little, in light weight, efficient is high, temperature rise is low forced air cooling high thrust flat three-phase linear asynchronous motor.In order to achieve the above object, the technical solution used in the present invention is: a kind of forced air cooling high thrust flat three-phase linear asynchronous motor, form by primary and secondary, elementaryly constitute by elementary iron core and the winding that is positioned at elementary iron core, cooling system is by blower fan, plenum chamber, the end air compartment, the side deep bead constitutes, at least one typhoon machine is installed on plenum chamber top, the plenum chamber both sides connect the end air compartment respectively, plenum chamber is communicated with the end air compartment and forms gas channel, this passage arrives winding overhang, motor both sides installation side deep bead, preceding Device for clearing away obstacle is fixed on the front end-plate, back Device for clearing away obstacle is fixed on the end plate, winding is connected with special-purpose variable frequency power supply by binding post, secondary is rectangular plate shape, magnetic conductive board is welded on the bearing, conductive plate is by being bolted on the bearing, conductive plate is installed front hanger respectively by being bolted on the bearing the outer top, two ends of plenum chamber, after gallows, have the downward air outlet of many row of openings on the side deep bead, plenum chamber top symmetry is installed two typhoon machines, elementary iron core is with bolt clamping plate and punching to be fixed as one, punching is made of one by fin and electromagnetism punching, radiation tooth is a dome, radiating groove is a round bottom, and radiating groove is dovetail groove shape wide at the top and narrow at the bottom.Adopt the city rail vehicle of technical solution of the present invention traction, cost is low, and tunnel cross-section can reduce about 30%-50%, will save about 100,000,000 yuans/kilometer of fund than traditional subway.And can increase substantially the propulsive efficiency of train, reduce system energy consumption.Simultaneously, it is low also to have noise, climbing capacity is strong, advantages such as radius of turn is little, and layout of roads is simple are a kind of energy-conserving and environment-protective, powerful, the novel rail technology flexibly of turning has very wide application prospect, and it is the great technological innovation and the development in future trend of traditional wheel track traffic.The present invention has carried out improving invention at the demand of high thrust linear electric motors city rail vehicle on the basis of existing technology, and forms production domesticization.
Technique effect of the present invention:
1, design of electrical motor is a forced air cooling, and volume is little, and is in light weight, and thrust is big.
2, fin is arranged at iron core top, increases area of dissipation, helps heat radiation, and good cooling results reduces electric machine temperature rise.
3, winding is the moulding winding, and sectional area of wire is big, and load current is big, and thrust is big.Under the large impact electromagnetic force, impact resistance is strong, and it is not fragile to insulate.
4, the cooling system structure compactness occupies little space, and air channel structure is reasonable, and wind flow is unobstructed, good cooling results.
5, the compact conformation of design of electrical motor, it is little to take up room; Convenient disassembly is installed reliably.
6, motor is connected with car body with 3 lift-on/lift-off types, has reduced the tie point of motor and vehicle, and is simple in structure, makes vehicle motor when walking stressed evenly.
