Description
Technical field
The present invention relates to field frame assembly, particularly relate to a kind of multiple hairpin and insert and be fixed in the slot of stator core and be in turn connected to form the field frame assembly of the hairpin formula winding electric machine of the coil windings of stator.
Background technology
Oil price rise violently and environmental problem impels people to study can to improve the various methods of vehicle fuel efficiency.Such as, a kind of electronic type four-wheel drive system (electric4wheeldrive:e-4WD) is had now.As everyone knows, mechanical type four-wheel drive system drives front-wheel by engine, and by power transmission shaft (propellershaft) and shaft coupling (coupling) to the actuating force of trailing wheel delivery engine to drive trailing wheel.Electronic type four-wheel drive system is a kind of mode being improved above-mentioned traditional mechanical type four-wheel drive system by motor, and front-wheel is driven by engine, and trailing wheel is driven by motor.Therefore, electronic type four-wheel drive system there is no need for power transmission shaft or the shaft coupling of transmission engine actuating force, can combine improve the fuel efficiency of vehicle with regeneration brake system etc.
Effectively playing function to make above-mentioned electronic type four-wheel drive system or fuel efficiency significantly improves, the motor of high-power compact need be developed.Be that electric automobile (electricvehicle) or various types of hybrid vehicle (hybridvehicle) of active force equally all needs this motor with electricity.
Usually, the power output of motor is directly proportional to coil turn (turn) number being wound on stator core.But increase the words stator core of the number of turn or the corresponding increase of size of motor of coil, be unfavorable for the miniaturization of motor.Therefore, in order to improve the power output of motor while not increasing motor size, the scheme of the fill-in ratio increasing the coil be wound on stator core can be adopted.That is, coil fill-in ratio is improved by the space reduced as far as possible between space between stator core and the coil of winding or each coil.From this angle, adopt now the scheme with the flatwise coil (flatcoil) of corner section in active research, to replace using loop coil coil windings with circular cross-section.Flatwise coil compared to loop coil, because its fracture morphology makes it possible to reduce space, improves fill-in ratio.
But flatwise coil is compared with loop coil, be not easy to carry out coil-winding operation.In order to maximize fill-in ratio, flatwise coil needs to be made into section and is greater than loop coil, and therefore rigidity increases, and is difficult to use coil winding machine.Consider this problem, have now a kind of the multiple hairpins be separated are inserted respectively be fixed to stator core after successively each hairpin of solder joints form the method for coil windings, this method is convenient to the coil winding operation of flatwise coil.The motor (hereinafter referred to as " hairpin formula winding electric machine ") of coil windings is formed by said method, multiple hairpins of U-shaped or V-shaped are inserted after being fixed to each slot of stator core, solder joints is configured in the hairpin in each slot successively, to form the coil windings of stator core.Therefore, hairpin formula winding electric machine can overcome the device restriction of coil winding machine, even flatwise coil also relatively easily can carry out coil-winding operation, and can improve the fill-in ratio of coil, thus can realize the motor of high-power compact.
But because described hairpin needs to be made into V or U-shaped, and owing to coil cannot be made into V or U-shaped in mould, therefore need bending each hairpin, process number increases.
Further, also need after the hairpin bending to V or U-shaped is inserted into stator core, with being connected tail wire circle, therefore also to need coil bending operation.Afterwards, need the coil be connected to each other through bending, therefore also must carry out welding sequence.As above, guarantee that the height of the situation lower coil end of the weld part of coil rises unavoidable, therefore the corresponding increase of motor size.
Further, owing to having suffered destruction through the insulating coating of coil of welding, therefore also need in addition to the insulator of welding position epoxy resin coating and so on, insulator sclerosis also needs a period of time, therefore subsequent processing Late phase is seasonable between.
