Abstract
The utility model relates to a magneto generator, comprising a motor shell body composed of a front end cover and a back end cover, a stator winding arranged on the inner wall of the motor shell body, a permanent-magnet rotor movably connected in the center of the motor shell body. The utility model is characterized in that the permanent-magnet rotor in the shell body is fixedly connected with a fan which is made of non-magnetic conductive materials. The utility model has the advantages that the heat of the generator is discharged in time, and the rotor can not be stuck with iron filings when correcting the balance.
Description
The utility model relates to a kind of permanent magnet generator, particularly a kind of permanent magnet generator.
Existing permanent magnet generator, its cooling fan all are external at the belt pulley place.During work, cooling air enters from commutator end bearing support bracket, at first cools off rectifier cell, cools off stator winding then, is discharged by fan by front end housing at last.This kind fan external permanent magnet generator has the following disadvantages:
1, cooling air passway is oversize, can not drain by very fast heat with generator, thereby makes the generator heating serious.
2, rotor adopts difficult removing of iron filings that is stained with when going heavy method smoothing to weigh.
The permanent magnet generator that goal of the invention of the present utility model is to provide a kind of can in time drain the heat of generator, rotor can not glue iron filings when smoothing weighing apparatus.
The utility model is to realize like this, its structure comprises electric machine casing, the cover cap that is positioned at the rear end cap end, the rectifying and voltage-stabilizing device that places cover cap that are made of front end housing, rear end cap, place stator winding on the electric machine casing inwall, loose joint is in the p-m rotor at electric machine casing center, the front end housing, rear end cap that its special feature is to constitute electric machine casing radially, be axially arranged with ventilation hole.During work, cooling air is divided into two-way, and one the road enters from the cover cap axial ventilation hole, and cooling rectifying and voltage-stabilizing device enters in the rear end cap by the rear end cap axial ventilation hole then and directly stator winding cooled off, and drains from rear end cap radial ventilation hole at last.Another transportation work style the past end cap axial ventilation hole enters in the front end housing and directly stator winding is cooled off, and last end cap radial direction ventilation hole is in the past drained.
Here, the both sides of the p-m rotor in the electric machine casing are connected with centrifugal fan, and centrifugal fan is to be made by non-magnet material.Like this, the cooling air that enters in the housing directly cools off stator winding under the drive of centrifugal fan, thereby has improved cooling effect.
The utility model compared with the prior art because fan is built in the electric machine casing, the heater element of the direct cooled electric generator of wind that fan blew out and aspirated, cooling air duct is shorter, the heat of generator just can in time be drained like this, good cooling results; The fan that utilizes built-in non-magnet material to make is removed material smoothing weighing apparatus, and the smear metal that is produced can not be bonded on the rotor, therefore than easy-clear.
Fig. 1 is a structural representation of the present utility model.
Now in conjunction with the accompanying drawings and embodiments the utility model is described in further detail;
As shown in Figure 1; the utility model is mainly by electric machine casing; place the stator winding 5 on the electric machine casing inwall; loose joint constitutes in the p-m rotor 6 at electric machine casing center; its special feature is to be connected with on the p-m rotor 6 in electric machine casing back centrifugal fan 4; preceding centrifugal fan 8; before; back centrifugal fan 4; the 8th, make by non-magnet material; electric machine casing is by front end housing 7; rear end cap 3 constitutes; front end housing 7; rear end cap 3 axially; radially be equipped with cooling air port 10; 11; be provided with rectifying and voltage-stabilizing device 2 in the outside of rear end cap 3; the outside of rectifying and voltage-stabilizing device 2 is provided with cover cap 1 and avoids extraneous destruction with protection rectifying and voltage-stabilizing device 2, is connected with belt pulley 9 on the output shaft of p-m rotor 6.
During work, belt pulley drives rotor rotation, and the cooling fan at p-m rotor two ends can directly cool off stator winding.Cooling air duct is divided into two parts, a part enters from the cover cap axial ventilation hole, and cooling rectifying and voltage-stabilizing device enters the aft-fan middle part by the rear end cap axial ventilation hole then, drive by fan again and directly stator winding is cooled off, drain from rear end cap radial ventilation hole at last.The wind of another part end cap axial ventilation hole in the past enters the forefan middle part, is driven by fan and directly stator winding is cooled off, and last end cap radial direction ventilation hole is in the past drained.
Claims (2)
1, a kind of permanent magnet generator, comprise electric machine casing, the cover cap that is positioned at the rear end cap end, the rectifying and voltage-stabilizing device that places cover cap that constitute by front end housing, rear end, place stator winding on the electric machine casing inwall, loose joint is in the p-m rotor at electric machine casing center, the front end housing, rear end cap that it is characterized in that constituting electric machine casing radially, be axially arranged with ventilation hole.
2, permanent magnet generator according to claim 1 is characterized in that the both sides of the p-m rotor in the electric machine casing are connected with centrifugal fan, and centrifugal fan is to be made by non-magnet material.
