Embodiment
The structural representation that inspires the integral type motors referring to Fig. 1,6,7 as can be known, this motor adopts permagnetic synchronous motor, this is kind of a same ac synchronous motor that adopts permanent magnet rotor 11 with the ISG permanent magnetic brushless, except excitation winding replaces with permanent magnet, basically identical with synchronous machine, the smooth transition conversion of the electric machine controller implementation pattern that matches realizes the starting and the power generation mode operation of motor.Mainly be provided with electric machine casing, protecgulum 7, bonnet 7, signal cap 8, stator 10, rotor 11, rotor supports 12 and axle 13.Permanent magnet partly produces magnetic flux at the air gap of motor, and the stator coil of reinforcement produces electromagnetic pole.Rotor 11 produces rotation under the traction of stator coil, when adding suitable frequency on the coil phase of stator 10, stator produces the rotating magnetic field that continues.Make stator and rotor produce the moment of torsion that needs by control, carry out synchronous feedback control by rotor 11 positions.For the position (position in magnetic field) of measuring rotor 11, on the rotor 11 of motor, Hall element 9 is installed, hall signal triggering dish is fixed on the flywheel, the plug connector of wire harness is fixed on the electric machine casing, the outside sending and receiving motivation of motor, the rotor 11 of its motor is fixed together by the bent axle of rotor supports 12 with engine, can drive engine rotation.
Inspiring the stator 10 of integral type motor is silicon steel sheet and top winding around, is fixed on by bolt and alignment pin on the last keyway 4 of electric machine casing inwall, and its lead terminal is fixed on the pottery of electric machine casing.The whole aluminum casting of electric machine casing has enough intensity; The electric machine casing both ends of the surface adopt the flange docking mode with being connected of engine, reducer shell respectively; The structure of housing is considered to help air-cooled.Its rear and front end is provided with protecgulum 6 and bonnet 7, and its material plastic material has dustproof and the fixedly effect of Hall element 9.
Referring to Fig. 2-5, for motor of the present invention is provided with the water-cooled system, is specially and adopts casting integrated formula method that cooling water channel 2 is cast directly in water jacket 14 inside, the intake-outlet 1 of water channel is arranged at homonymy.Inwall is provided with the keyway 4 that stator 10 is installed, outer wall is provided with the location hole 5 of fixed electrical machinery, around water channel, be provided with the clearance hole 3 of fabrication hole that shake out in order to after casting is finished, to discharge core, clearance hole 3 should block up with obstruction after machining, and can adopt bowl-type to stop up or the screw thread obstruction.It is for the water jacket part being extend in the gearbox clutch housing to save axial space, can not making stairstepping if arrangement space meets the demands that water jacket 14 is made stairstepping.Shown the cross sectional shape of water channel 2 referring to Fig. 5 portion cutaway view, water channel 2 indoor designs heat radiating fin structure, to increase area of dissipation.In general, the big more more cooling fluids of dress that help more of the degree of depth of water channel 2, the many more big more more heats that help more discharging of fin.But the concrete size of water channel 2 should be determined according to the result who arranges, determine under the prerequisite that satisfies arrangement requirement and performance requirement.For the ease of casting, the width of fin can not be less than 4mm, and the distance between the fin should be less than 4mm, and the degree of depth of water channel 2 should strengthen more than 4mm and as far as possible.The wall thickness of water jacket 14 should be less than 4mm, otherwise cooling fluid is easily by the thin-walled seepage.And the too thin casting flaw that is easy to generate of wall.The suggestion wall thickness guarantees more than 6mm under the prerequisite of arrangement requirement satisfying.
The keying of the concrete ECU (Electrical Control Unit) of inspiration integral type motor of the present invention control motor, speed and be provided with communication interface with external device communication.The CAN communication interface that its motor control unit is reserved, so as with car in other electronic control units carry out exchanges data by the CAN bus mode, in time motor output signal, function signal are sent to Engine ECU.And the function of this control unit decision electrical machine working mode; can comprise electric model, power generation mode and shutdown mode according to the mode of operation of the control motor/generators such as state of state, power drive system state and the external equipment of user's request, energy storage units.
