The content of the invention
Technical problem to be solved in the utility model is:A kind of overcome the deficiencies in the prior art, there is provided temperature in use model Enclose plant protection unmanned plane motor wide, simple in construction, that forward and reverse frequent changes startup can be achieved.
The utility model solves the technical scheme that its technical problem uses:The plant protection unmanned plane motor, including rotor And stator, it is characterised in that:Described rotor and stator are superimposed up and down to be sleeved on the axle being vertically arranged, and stator is consolidated by stator support It is scheduled on the inside of the output end of axle, rotor is rotatably installed in the top of stator by rotor field spider, and stator is nested with stator winding.
Rotor of the present utility model does not have winding and magnet, due to not having permanent magnet on rotor, therefore allows higher temperature Rise, meet the larger applicable situation of temperature span.Because winding is arranged on stator, it is easier compared to traditional magneto Cooling, efficiency high, loss are small;Using the structure being superimposed up and down between rotor and stator, the rotary inertia of rotor is small, there is higher turn Square ratio of inertias, and have frequent starting(1000 times/hour)Ability, be especially suitable for forward and reverse operating special occasions use, and Starting current is small, and detent torque is big, and more prominent during low speed, accordingly, control circuit power is simple, volume miniaturization, has Higher economy and reliability.
Described rotor and the upper and lower end face of stator are provided with end face axial trough, stator be provided with it is multiple be used to wearing stator around The winding perforation of group.
Without any secondary operation, stator winding is molded using three-phase windings coiling, and the overall embedded molten slot insulation of warp coats Stator on set winding perforation in;Magnetic circuit uses axial magnetic flux.
Described rotor field spider is fixedly set in the inner ring of rotor, and stator support is fixedly set in the inner ring of stator, rotor Support is rotatablely connected axle by bearing.Rotor field spider and stator support are preferably made using aluminium alloy post, and integral material utilizes Rate is high, weight saving, reduces power consumption.
The top of described rotor field spider is provided with end cap fixed mechanism, and end cap fixed mechanism includes connecting seat and end cap, even Joint chair is fixed on the top of rotor field spider, is sleeved on outside the upper end of axle, and the top of rotor field spider is provided with end cap.
The lower section of described rotor field spider is provided with Hall sensor, and Hall sensor is sleeved on the axle below rotor field spider On.
The upper and lower ends portion of described axle is separately installed with shaft block ring, and the output end of axle is provided with flat key.
Compared with prior art, beneficial effect possessed by the utility model is:Rotor of the present utility model does not have winding And magnet, due to there is no permanent magnet on rotor, therefore allow higher temperature rise, meet the larger applicable situation of temperature span.By It is arranged in winding on stator, is easier to cool down compared to traditional magneto, efficiency high, loss is small;Rotor and stator it Between using the structure that is superimposed up and down, the rotary inertia of rotor is small, has higher torque ratio of inertias, and have frequent starting(1000 times/small When)Ability, the special occasions for being especially suitable for forward and reverse operating uses, and starting current is small, and detent torque is big, during low speed more For protrusion, accordingly, control circuit power is simple, volume miniaturization, has higher economy and reliability.Integrated motor weight Amount is reduced, efficiency high, and power consumption is low.Reliability is high, and maintenance rate is low.Manufacturing process easily realizes production in enormous quantities, product quality one Cause property is high, and holistic cost, which has, significantly to be declined.
