Abstract
The invention provides a double-water cooled flat linear synchronous machine with permanent magnets with unequal width, which consists of a primary coil and a secondary coil, wherein the primary coil consists of a primary iron core, a winding, cooling tubes, cooling flexible belts and a shell; the cooling tubes are uniformly distributed at the bottom of each tooth groove of the primary iron core according to square wave form; the motor winding is distributed on the upper parts of the cooling tubes; the cooling flexible belts are respectively arranged on the two sides of the winding; after required water pressure is charged into the cooling flexible belts, the cooling flexible belts are fully contacted with the end part of the winding; the upper face and the lower face of the shell are stainless steel plates; the four side faces of the shell are aluminum alloy plates; high-heat conduction resin is poured into small clearances in the primary coil; the secondary coil consists of a plurality of same modules; and each module consists of a monomer permanent magnet, a multi-body permanent magnet and a secondary magnetic yoke plate. The width of the monomer permanent magnet and the multi-body permanent magnet is different, so the distribution of gap magnetic fields is changed, the positioning force torque of the tooth grooves is low, and the aim of optimizing the performance of the motor is fulfilled.
Description
Technical field: the present invention relates to the three-dimensional water cooled flat linear synchronous generator of a kind of not wide permanent magnet.
Background technology: flat type permanent magnetic synchronous linear electric motors water-cooling system mostly adopts in electric motor primary iron core yoke section and adopts round copper pipe water flowing cooling at present, because the main pyrotoxin of motor is the motor winding, heat will just can pass to cooling water pipe by thermal resistances such as insulation and iron cores, it is convenient for cooling water pipe is installed, mostly be installed in the open slot, the contact area of copper pipe and iron core also mostly is circumference half, can't take full advantage of the area of dissipation of cylindrical duct.Because permanent magnet and slotted core interact, and permagnetic synchronous motor produces Cogging Torque inevitably, causes the motor force oscillation, produce thus vibration in addition, affect positioning accuracy.Industry adopts the method for oblique magnetic pole or skewed slot mostly at present, but because the angle of inclination precision prescribed is higher, the very large difficulty of just bringing to processing.
Summary of the invention: the purpose of this invention is to provide a kind of long-pending little, lightweight, noise is low, positioning accuracy is high, easy care, be fit to the high-performance permanent magnet synchronous machine produced in enormous quantities.Technical scheme of the present invention is: the two water cooled flat linear synchronous generators of a kind of not wide permanent magnet, formed by elementary (1) and secondary (2), elementary by elementary iron core (3), winding (4), cooling water pipe (5), cooling flexible-belt (6) and casing (7) form, cooling water pipe (5) is evenly distributed on each gullet base of elementary iron core (3) by square-wave form, cooling water pipe (5) top distribution motor winding (4), a cooling flexible-belt (6) respectively is installed in winding (4) both sides, cooling flexible-belt (6) fully contacts with winding overhang after being filled with the hydraulic pressure of requirement, casing (7) upper and lower surfaces are corrosion resistant plate, four sides are aluminium alloy plate, in the slight void of elementary inside, pour into a mould high thermal conductive resin (8), secondary (2) are comprised of a plurality of identical modules, each module is by monomer permanent magnet (9), many bodies permanent magnet (10), secondary magnetic yoke plate (11) forms, monomer permanent magnet (9) is different with the width of many bodies permanent magnet (10), monomer permanent magnet (9) only has one, many bodies permanent magnet (10) has some, monomer permanent magnet (9), many bodies permanent magnet (10) is arranged in parallel within on the secondary magnetic yoke plate (11) of low-carbon steel material by rule, every monomer permanent magnet (9), many bodies permanent magnet (10) is the identical distance in interval all, cooling water pipe (5) is the pipe of being made by copper or aluminium, cooling flexible-belt (6) is composite material, to be pressed into by the macromolecular material of high flexibility and the metal material layer of high-termal conductivity, cooling flexible-belt (6) is by after the hot pressing, form the water route of square-wave form, cooling flexible-belt (6) can fully contact with winding in the irregular slit of casing and winding, cools off.If the permanent magnet of secondary module adopts identical shape, the same position of each corresponding elementary tooth in permanent magnet center, the location torque of teeth groove superposes like this.And after adopting not wide permanent magnet, the diverse location of the corresponding elementary tooth in permanent magnet center has changed the air-gap field distribution, and Cogging Torque is diminished, and has reached the purpose of optimizing motor performance.
Technique effect of the present invention:
1, the electric motor primary cooling system adopts cooling water pipe and cooling flexible-belt, and cooling water pipe directly contacts iron core, and the cooling flexible-belt directly contacts winding, and heat radiation has improved heat-sinking capability simultaneously, can make motor bear larger electric current, thereby increase substantially motor thrust.
2, the not wide permanent magnet of secondary employing has weakened Cogging Torque, and magnet steel is cuboid, and easily processing by the equipment of routine, just can reach higher precision, has reduced processing cost.
