Embodiment Construction
[0042] The present invention will be further described in conjunction with accompanying drawings.
[0043] Air-liquid interweave cooling for high power density motors, such as Figure 1-Figure 9 As shown, the device includes: a stator, a rotor and a cooling system thereof, stator slots 1-1 are evenly distributed along the circumferential direction on the stator core 1, and discharge armature windings 1-2 are embedded in the slots.
[0044] The cross-sectional area of the armature winding 1-2 is less than 30% to 50% of that of the stator slot 1-1, and its end value or any value in the middle can be selected.
[0045] The armature winding 1-2 is wrapped with an insulating sleeve 1-3.
[0046] The insulating casing 1-3 wrapping the armature winding 1-2 and the stator slot wedge 1-4 are supported by a non-metallic T-shaped bracket 1-5.
[0047] The inner wall surface of both sides of the stator slot 1-1, the inner surface of the stator slot wedge 1-4 and the outer surface of t...
