And if being fixed on U-shaped iron core, wherein the inside of U-shaped iron core is equipped with the rotor chamber for adapting to PM rotor, PM rotor
It is movably arranged in rotor chamber.
The side of shell is fixed with L-type mounting structure, and L-type mounting structure edge is fixed with terminal plate;The synchronous motor
By being fixed on L-type mounting structure, shaft is goed deep into shell and is connect with impeller, and terminal plate welds contact pin or weldering by exempting from by lead
Line contact pin is electrically connected coil windings.
Preferably, being equipped with the connection buckle of movable bending on bobbin winder bracket along edge, bobbin winder bracket passes through connection lock joint.
Preferably, exempt to weld the enameled wire for being embedded with coil windings in contact pin slot, it is described to exempt to weld contact pin equipped with for clipping broken
The clamp of magnet wire insulation skin stitches.
Preferably, rotor chamber both ends are respectively fixed with rear end cap and with support bracket fastened drive end bearing bracket, the shafts
Both ends are each passed through the fore bearing room of drive end bearing bracket and the rear bearing room of rear end cap.
Further, drive end bearing bracket and rear end cap are equipped with the positioning convex platform for being embedded in rotor chamber close to the side of U-shaped iron core.
Preferably, terminal plate is equipped with the binding post for external alternating current, the binding post is fixed by plastic package process
On terminal plate.
Beneficial effects of the present invention: using the synchronous machine drives blower directly inputted using exchange, without rectification and nothing
Brushless motor drive module, efficiency are higher than motor with cup rotor or capacitor motor, and low noise, at low cost, have objectively raw
Produce benefit.

Specific embodiment
To be more clear the purposes, technical schemes and advantages of the embodiment of the present invention, below in conjunction with embodiment and attached drawing,
The invention will be further described.
Embodiment
A kind of exchange cross flow fan, as shown in Figure 1-3, include blower 1 and synchronous motor 2, wherein blower 1 includes shell 3
And the impeller 4 in shell 3, synchronous motor 2 include rotor assembly and stator module, rotor assembly includes PM rotor
5 and its shaft 6, stator module include stator skeleton 7 and U-shaped iron core 8.As shown in figure 5, stator skeleton 7 includes two hollow
Bobbin winder bracket 7-1 and Plug pin patch bay 7-2 positioned at the bottom bobbin winder bracket 7-1, the periphery bobbin winder bracket 7-1 are equipped with coil windings, Plug pin patch bay 7-2
Several groups contact pin slot is inside offered, contact pin slot includes exempting to weld contact pin slot 7-2-1 and manual welding access slot 7-2-2, wherein exempts to weld contact pin
Adaptation is equipped in slot 7-2-1 exempts to weld contact pin 9, and the bonding wire contact pin 10 of adaptation is equipped in manual welding access slot 7-2-2.Stator skeleton 7
