Figure 18 is the vertical profile side view of the example of the drive unit 6 of expression use brushless direct current motor.This example since can be in 1 motor field frame optionally embedding the stator core of the shared induction conductivity of shape and the stator core of brushless direct current motor, and can be in the rotor of the rotor of induction conductivity and brushless direct current motor shared inboard input axial region, so this example is characterised in that the structure of motor with respect to aforementioned example.Correspondingly, the no longer repeat specification of constitutional detail that all and aforementioned example is identical.
Brushless direct current motor in this example is that 1 stator core 52a goes up stator 52 is constituted around volume stator winding 52b, and stator core 52a embedded motor field frame 43 and is the clamping shape and fixes by sticking up projection 43a and bending pawl 43b outward.Distance piece 53 is that the difference to the size of the stator core 44a of the axial dimension of this stator core 52a and the induction conductivity in the aforementioned example compensates.
Rotor 54 ties up to the periphery mounting permanent magnet magnetic pole 54b of rotor core (yoke) 54a, and on the 36d of portion by the motor rotor embedding that the installation wheel hub 54c with these integrally formed insulating resin systems is installed among the inboard input axial region 36g.The engagement jog 54d that embedding is formed at the engagement projections 47f on the sliding part 47c of clutch mechanism 47 of engagement on wheel hub 54c is installed and with this installation wheel hub 54c ester moulding integratedly.Wheel hub 54c is installed the size of and installing with the rotor 45 same embeddings of induction conductivity on the 36d of portion in the motor rotor embedding for forming, rotor core 54a is exposed at interior distolateral place, fastening end, and becket 54e is embedded in outer distolateral place, fastening end.
In addition, the installation wheel hub 54c of rotor also can import axial region with the inboard of the special use of the motor rotor embedding portion of wearing shortening size by use and form short size.
In addition, permanent magnet poles 54b constitutes the standing shape laterally than stator winding 52b, and by relative with the rotary track of this protuberance and magnetic pole detecting element 55 is set and the rotary position of rotor 54 is detected.This magnetic pole detecting element 55 is installed on the case 48.
Brushless direct current motor constitutes the drive current that the relative position with respect to the magnetic pole 54b of the rotor 54 of each phase of stator winding 52b was detected and be by convection into each phase of this stator winding 52b and controls as is generally known, and detailed description is omitted.
In using the automatic washing machine of this brushless direct current motor, in above-mentioned drive circuit 17f, be provided with and be used for motor and carry out the phase inverter that PAM controls with the rectification circuit of dc source with to each phase current of stator winding 52b.
Also can realize the automatic washing machine same even adopt this drive unit 6 with aforesaid example.And, because brushless direct current motor can carry out various revolution control, so can carry out more careful washing procedure and dehydration procedure.
Yet, when optionally packing into, must consider to constitute their stator and the gabarit of rotor and the size of fitting portion at shared this motor field frame 43 and inboard input axial region 36g and with induction conductivity or brushless motor.
For the contour dimension that obtains same output bigger with induction conductivity usually.Therefore, it is necessary the stator 44 of induction conductivity and rotor 45 being discussed.
Considering the total of automatic washing machine, must be that 34 be axle center and the clutch mechanism that vertically meshes with planetary reduction gear constitute from the installed surface overhang downwards to the bottom surface of water jacket 5 with the drive unit 6 of the concentric arranged in series formation of motor is in the 160mm with the driving rotational axle.And, be that 34 ball bearing 33a, 33b must be provided with big as far as possible interval vertically because this drive unit 6 for being that 34 upper end is installed and supported washing and dewatering groove 2 and agitator 4 at the driving rotational axle, supports this driving rotational axle.Correspondingly, reducing gear shell 32a, the 32b that this ball bearing 33a, 33b be set is the axial dimension suitable with the axially spaced-apart of ball bearing 33a, 33b.
From these dimension Distribution, the axial dimension of motor comprises the clutch mechanism 47 of engagement being 90mm.Induction conductivity preferably increases the diameter of stator 44 and rotor 45 for suppress axial dimension when keeping necessary output characteristics (about 250W).Yet, accomplish 44a unshakable in one's determination, the 45a of stator 44 and rotor 45 are constituted with steel plate punching press and lamination, the 44a unshakable in one's determination that diameter is big, the price of 45a will be very high.
