Description
Technical field: the utility model relates to the three-dimensional water-cooled platypelloid type of a kind of not wide permanent magnet linear synchronous generator.
Background technology: platypelloid type permanent magnetic linear synchronous motor water-cooling system is employed in electric motor primary iron core yoke portion mostly and adopts round copper pipe water flowing cooling at present; Because the main heating source of motor is a motor windings; Just heat will can pass to cooling water pipe through thermal resistances such as insulation and iron cores, for it is convenient that cooling water pipe is installed, is installed in the open slot mostly; The contact area of copper pipe and iron core is also mostly to be half circumference, can't make full use of the area of dissipation of cylindrical duct.Because permanent magnet and slotted core interact, and permagnetic synchronous motor produces the teeth groove location torque inevitably, causes the motor force oscillation, produce vibration thus in addition, influence 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 big difficulty of just bringing to processing.
Summary of the invention: the purpose of the utility model provide a kind of long-pending little, in light weight, noise is low, positioning accuracy is high, easy care, be fit to the high-performance permagnetic synchronous motor produced in enormous quantities.The technical scheme of the utility model is: the two water-cooled platypelloid type linear synchronous generators of a kind of not wide permanent magnet, forms by primary and secondary, and elementaryly be with and casing is formed by elementary iron core, winding, cooling water pipe, cooling are flexible; Cooling water pipe is evenly distributed on each gullet base of elementary iron core by square-wave form; Distribution motor windings in cooling water pipe top is respectively installed one in the winding both sides and is cooled off flexible band, fully contacts with winding overhang after the cooling flexibility is with the hydraulic pressure that charges into requirement; The casing 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, secondaryly are made up of a plurality of identical modules; Each module is made up of monomer permanent magnet, many bodies permanent magnet, secondary magnetic yoke plate; The monomer permanent magnet is different with the width of many bodies permanent magnet, and the monomer permanent magnet has only one, and many bodies permanent magnet has some; Monomer permanent magnet, many bodies permanent magnet are arranged in parallel within by rule on the secondary magnetic yoke plate of low-carbon steel material, the distance that every monomer permanent magnet, many bodies permanent magnet are all identical at interval.
If the permanent magnet of secondary module adopts identical shape, each permanent magnet center is the same position of corresponding elementary tooth all, and 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 the teeth groove location torque is diminished, and has reached the purpose of optimizing motor performance.
The technique effect of the utility model:
1, the electric motor primary cooling system adopts cooling water pipe and the flexible band of cooling, and cooling water pipe directly contacts iron core, and the flexible band of cooling is the contact winding directly, and heat radiation has improved heat-sinking capability simultaneously, can make motor bear bigger electric current, thereby increase substantially motor thrust.
2, the not wide permanent magnet of secondary employing has weakened the teeth groove location torque, and magnet steel is cuboid, and processing through the equipment of routine, just can reach higher precision easily, has reduced processing cost.
