Description
Technical field
The utility model is related to a kind of motor, more particularly, to a kind of double cooling electric machine structures.
Background technology
Existing motor uses water cooling and air-cooled two ways mostly, and motor radiating is slower, and temperature rise is very fast, cooling effect
Not substantially, it is easily caused motor and often works at relatively high temperatures；So as to reduce the service life of motor, control to motor and
Output can all be impacted.
The content of the invention
The utility model purpose is：There is provided one kind be not only simple in structure, it is easy to use, and using oil cooling additional cast iron
The mode of block auxiliary heat dissipation, makes motor work at relatively low temperatures, and improve double cooling motor knots of its service life
Structure.
The technical solution of the utility model is：A kind of double cooling electric machine structures, including water cooling casing, and located at the water
Machine shaft, stator, rotor in cold shell；The rotor is set on the machine shaft, and the stator is fixed on described
On water cooling casing madial wall；The water cooling casing includes casing ontology, and is respectively arranged on the front end at the casing ontology two ends
Lid and rear end cap；Cooling oil is provided with the water cooling casing, heat-conducting block is fixed with end cap in the rear, while in the rear
The oil guiding hole of cooling oil and heat-conducting block is communicated with end cap；Cooling oil during motor rotates by the rotation of rotor,
Oil drive is rotated and stator line bag is cooled down, and line bag temperature is passed into water cooling casing as early as possible, is cooled down simultaneously
Oil flows to casting pig by the oil guiding hole of rear end cap（Heat-conducting block）On, casting pig heat conduction is fast, and the temperature of cooling oil can be absorbed as early as possible,
And heat spreader to outside motor is accelerated by the radiating of motor by the naked part being exposed on the external, reduce the work of motor
Temperature, improves electrical machinery life.
As preferred technical scheme, the two ends of the machine shaft are fixed on the drive end bearing bracket and described by bearing
On rear end cap.
As preferred technical scheme, the heat-conducting block is casting pig.
As preferred technical scheme, the stator is connected with hall circuitboard, while being correspondingly arranged with the rotor.
The utility model has the advantages that：
1. the utility model uses oil cooled mode, additional casting pig auxiliary heat dissipation（Cast iron materials heat exchange effect
By force）；Oil has good thermal balance ability, and superpower capacity of heat transmission can ensure that motor is in optimal working condition；Together
When casting pig heat conduction and radiating effect it is stronger, can absorb motor operation produced by heat, with the external world carry out heat exchange, from
And make motor work at relatively low temperatures, without adding antifreezing agent, it is to avoid cavitation erosion, incrustation scale, electrolysis etc. are corroded to motor
Injury, improve the life-span of motor, there is good application prospect.
