Description
One, technical field:
The utility model relates to a kind of reluctance motor, especially directly drives electric vehicles wheel switched reluctance motor.
Two, background technology:
At present, the electric vehicles motor that everybody was familiar with adopts alternating current machine mostly, direct current machine or brshless DC motor, and the wheel shell-type switched reluctance motor of prior art.Adopt alternating current machine, direct current machine or brshless DC motor, can not directly drive motor vehicle, speed changer, driving shaft and differential mechanism must be passed through and motor vehicle could be driven, its manufacturing process complexity, the production cost height, it is big to take up room, running noise is big, breakaway torque is little, and energy loss is big, in use is subjected to the restriction that different mechanical properties require.Because the casing of wheel shell-type switched reluctance motor separates with rotor core, therefore, rotor core and hub adopt machinery to be press-fitted composition by link, and are a kind of four fixing phase motors, its manufacturing process complexity, and the production cost height, running noise is big.In addition, the photoelectric sensor of this motor separates with motor, must connect by support, and difficulty not only is installed, and the less stable in the operation process, thereby causes the accuracy of position probing, and torque is descended.
Three, summary of the invention:
The purpose of this utility model provides the wheel switched reluctance motor that a kind of wheel and motor are made as one.
Concrete scheme of the present utility model is: comprise motor shaft, stator core, magnetic pole, rotor core, casing, end cap, coil, photoelectrical position sensor, wheel, axle center hole, it is characterized in that: the A. rotor core is made of two above magnetic poles, it is cast in by nonmagnetic substance between casing, the peripheral formation of casing wheel steel ring, wheel are sleeved on the peripheral wheel rotor of forming of steel ring; B. stator core is provided with two above magnetic poles, and each magnetic pole is provided with coil, and the stator core end is provided with photoelectrical position sensor, and stator core is cast in by nonmagnetic substance between motor shaft and forms stator; C. the wheel rotor is distributed in the motor shaft both sides, and is connected as a single entity with motor shaft, and motor shaft connects end cap through bearing, and the end cap inboard is provided with the photoelectrical position sensor shade, and shade is provided with the shading tooth identical with the rotor core number of magnetic poles.
Between the rotor core and casing of such scheme, cast in together with nonmagnetic substance between stator core and the electric drive axle, constitute the integrated switch reluctance motor, wherein casing forms the wheel steel ring naturally, wheel is positioned on the peripheral wheel rotor that forms of casing, and reluctance motor need not pass through speed changer, and driving shaft and differential mechanism are just at the peripheral wheel rotor that forms of casing, reluctance motor need not pass through speed changer, and driving shaft and differential mechanism be direct powered vehicle just.Its compact conformation, simply, and photoelectrical position sensor and stator core are connected as a single entity, the optoelectronic position shade is arranged in the end cap, and the shading tooth on the shade is corresponding with number of magnetic poles on the rotor core, and rotor core and stator core are made of a plurality of magnetic poles, not only easy for installation, and can require to set the different different number of motor phases of rotor sum of series according to different mechanical properties, make vehicle operation steady, improved the accuracy that vehicle location detects.
Adopt the wheel switched reluctance motor of such scheme directly to drive motor vehicle, it is simple in structure, compactness, and conserve space, breakaway torque is big, and noise is little, operates steadily, position probing accuracy height, easy for installation, production cost is low.
Four, description of drawings:
Fig. 1 is a structural representation of the present utility model.
Five, embodiment:
Please see Figure 1, the utility model mainly is made up of motor 1, stator core 2, magnetic pole 3, rotor core 4, casing 5, end cap 6, coil 7, photoelectrical position sensor 8, wheel 9, bearing 10, bearing cap 11, photoelectrical position sensor shade 12, axle center hole 13 etc., it is characterized in that: A. rotor core 4 is made of two above magnetic poles 3, it is cast in by nonmagnetic substance between casing 5, casing 5 peripheral formation wheel steel rings, wheel 9 is sleeved on the peripheral wheel rotor of forming of steel ring; B. stator core 2 is provided with two above magnetic poles 3, and each magnetic pole is provided with coil 7, and stator core 2 ends are provided with photoelectrical position sensor 8, and stator core 2 is cast in by nonmagnetic substance between motor shaft 1 and forms stator; C. the wheel rotor is distributed in motor shaft 1 both sides, and is connected as a single entity with motor shaft 1, and motor shaft 1 connects end cap 6 through bearing 10, and end cap 6 inboards are provided with photoelectrical position sensor shade 12, and shade is provided with the shading tooth identical with rotor core 4 number of magnetic poles.
As can be seen from Figure 1: end cap 6 is arranged on casing 5 both sides, and is fastened on the wheel two ends of rotor by screw; Bearing 10 1 sides are spacing by the step of motor shaft 1, and opposite side is by bearing cap 11 location, and the axle center hole 13 in the motor shaft 1 is a through hole, and motor lines and position signalling line pass through from axle center hole 13.
