The battery driven vehicle explosion separation motor
Technical field
The utility model relates to the battery driven vehicle field, especially relates to the explosion separation motor that a kind of battery driven vehicle is used.
Background technology
At present, the explosion separation motor that uses on battery driven vehicle is the flame-proof type direct current machine, the design feature of direct current machine itself needs commutator exactly, and in the process of commutation, will produce electric spark, the principle of flame proof be videlicet motor this in the imflammable gas environment owing to spark is blasted, the explode spark of generation of spark that motor itself produces or motor internal can not cause that the environment outside the motor body blasts.The flame-proof type direct current machine also needs carbon brush in the needs commutator in addition, and carbon brush is a vulnerable part.Therefore this motor needs periodic maintenance maintenance, cleaning in use for some time.
The utility model content
The utility model provides a kind of explosion separation motors simple in structure such as commutator, carbon brush that do not need at the weak point of above-mentioned technology.
The realization the technical solution of the utility model is as follows:
The battery driven vehicle explosion separation motor, comprise cast-aluminum rotor, rotating shaft, stator, support, front end housing, rear end cap, outlet lid and termination, be connected with stator in the described support cavity, cast-aluminum rotor is connected in the rotating shaft, cast-aluminum rotor is positioned at the chamber of stator, preceding end bearing is installed on the axle journal of the front end of rotating shaft, the front end bearing fixing is indoor in the fore bearing of front end housing, one end of rotating shaft is exposed to front end housing, front end housing is fixedly connected on the support, the rear end of rotating shaft is fixedly connected with a rear end bearing, rear end bearing is fixed in that the rear bearing of rear end cap is indoor, and rear end cap is fixedlyed connected with support, and the top of support also is provided with outlet box, the outlet box both sides are equipped with termination, at the outlet box top outlet lid are installed.
The beneficial effects of the utility model are simple in structure, have removed the commutation spark problem, have improved the reliability of explosion insulation performance, can be non-maintaining, provide cost savings.
