Abstract
The utility model discloses an oil cooling type electric vehicle driving motor, comprising a stator (1), a rotor (2), a housing (3), and a front and a back end cover (4, 9). The oil cooling type electric vehicle driving motor is characterized in that the two ends of the housing are provided with an oil inlet (6) and an oil outlet (8), that the oil inlet and the oil outlet are connected with a radiator (7) with an oil pump, and that the stator and the rotor are immersed in special cooling oil (5). The utility model is a driving motor for electric vehicles with good heat dissipating effect, high electromagnetism load designed value, light weight and small volume.
Description
Technical field
The utility model relates to motor, especially relates to a kind of oil injection type electric vehicles drive motor.
Background technology
Because elec. vehicle adopts motor driven systems, has realized auto-exhaust zero-emission, be to generally acknowledge the environmental protection automobile in the world.Motor certainly leads to a large amount of losses as the power tool of energy converting between mechanical on the automobile when work, mainly contain stator copper loss, rotor copper (aluminium) consumption, core loss, mechanical wear etc., and these losses finally all become heat, and motor temperature raises.In order to make motor energy normal operation, must adopt certain type of cooling that these heats are distributed, motor temperature is controlled in the predefined range of temperatures.At present, the used drive motor of elec. vehicle generally adopts water cooling and fan cooling dual mode.The fan cooling mode is at motor external rotor axle fan blade to be housed, and the motor internal heat is passed to motor case and end cap earlier, with fan the heat on casing and the end cap is taken away again, and this mode radiating effect is poor; The water-circulating type of cooling is that the circulation water channel is set in casing, and motor internal heat conduction is earlier given casing and end cap, with circulating water the heat in the casing is taken away again, this structure radiating effect has bigger improvement, but the time one is long, is easy to generate incrustation scale in the water channel, and its cooling performance is had a greatly reduced quality.The major defect of above-mentioned two kinds of types of cooling be cooling media can not with the direct heat loss through convection of motor internal pyrotoxin, cause motor internal everywhere big temperature distributing disproportionation of the temperature difference even especially the rotor radiating effect is the poorest, thereby Electromagnetic Design is restricted, and motor weight is bigger.
Summary of the invention
The utility model is to solve the technical matters that prior art electric vehicles drive motor radiating effect is poor, the electromagnetic load design value is low, motor weight is bigger, proposes a kind of good heat dissipation effect, electromagnetic load design value height, in light weight, electric vehicles drive motor that volume is little.
For addressing the above problem, the technical solution of the utility model is:
A kind of oil injection type electric vehicles drive motor, comprise stator, rotor, casing, forward and backward end cap, it is characterized in that the two ends of described casing are provided with oil inlet, oil outlet, described radiator, described stator and the rotor that is connected with the band oil pump into and out of hydraulic fluid port is immersed in the special-purpose oil coolant.
Described drive motor is any electric vehicles drive motor in the middle-size and small-size oil injection type squirrel cage induction motor, permagnetic synchronous motor, switched reluctance machines of 10 to 150 kilowatts of rating horsepowers, 40 to 500 kilowatts of peak powers.
Characteristics of the present utility model be allow motor internal everywhere pyrotoxin directly carry out liquid thermal exchange with special-purpose oil coolant, enter motor internal again after the heat that liquid is taken out of cools off by external heat sink and absorb heat, having oil pump on the radiator makes oil circuit form circulation, from but radiating condition improved comprehensively, the temperature difference is less everywhere promptly to make motor internal, temperature traverse is comparatively even, and the heat-sinking capability of motor strengthens.Cooling performance water-cooled and air-cooled being greatly improved compared to prior art can increase motor electromagnetic load design value effectively, reduces motor volume and weight greatly, is specially adapted to the occasion that elec. vehicle has " lightweight, miniaturization " to require to motor.With compare with the torque water-cooled machine that can to reduce weight about about 1/4, and compare with the torque ventilated machine that can to reduce weight about about 1/3, the effect highly significant.
Description of drawings
Fig. 1 is the structure cutaway view of the utility model housing.
The specific embodiment
Shown in Figure 1, be a preferred embodiment of the present utility model.A kind of oil injection type electric vehicles drive motor, comprise stator 1, rotor 2, casing 3, forward and backward end cap 4,9, the two ends of described casing are provided with oil inlet 6, oil outlet 8, described radiator 7, described stator and the rotor that is connected with the band oil pump into and out of hydraulic fluid port is immersed in the special-purpose oil coolant 5.Because stator and rotor are the topmost pyrotoxins of motor, special-purpose oil coolant enters motor internal by front end oil inlet 6, flow to motor rear end by the air gap between the stator, and it is stirred by the rotation of rotor, flow out from the outlet of motor rear end then, enter motor internal again after the heat of taking out of cools off through radiator and form the cooling oil circulation.
The used for electric vehicle asynchronous speed-adjustable motor that can reach 1800 rev/mins of 90 kilowatts, rated speed of rotation with 22 kilowatts of rating horsepowers, the peak power of new development is an example, if employing air cooling way then motor total weight is about 105 kg, employing water-cooling pattern then motor total weight also will arrive more than 90 kilograms, dig at all and send out to satisfy the requirement of " exert oneself and want big, weight to want light ", when adopting the oil cooling mode to design, the total weight of motor is reduced to about 70 kilograms significantly, receives praises from customers.
Electric vehicles drive motor of the present utility model is drive motor such as the middle-size and small-size oil injection type squirrel cage induction motor, permagnetic synchronous motor, switched reluctance machines of 10 to 150 kilowatts of rating horsepowers, 40 to 500 kilowatts of peak powers.
