Abstract
A direct-current brushless motor provided by the utility model comprises a motor housing, a motor front end cover, a junction box and radiating ribs, wherein the edge of the motor front end cover is provided with fixing holes, the motor front end cover is connected with the motor housing by bolts via the fixing holes, the junction box is arranged on the motor housing and is connected with a motor wire, and the radiating fins are arranged outside the motor housing and have wavy surfaces. According to the utility model, the additional arrangement of screw holes makes the two components (the motor front end cover and the motor housing) better fixed together so that the motor housing and the motor front end cover cannot be cracked due to the jolt of a vehicle in the running process; the limitation on the length of the motor wire is addressed due to the additional arrangement of the junction box; and the heat radiation problem of the motor is solved because the radiating fins are changed from linear surfaces into wavy surfaces. The reliability of the motor is increased and the failure rate of the motor is reduced.
Description
Technical field
The utility model relates to the improvement of electric machine casing and electric motor end cap performance, particularly a kind of dc brushless motor.
Background technology
Dc brushless motor is comprised of motor body and driver, is a kind of typical electromechanical integrated product.Brushless electric machine refers to the motor of brushless and commutator (or collector ring), claims again commutatorless machine.
At present, the connected mode of the electric machine casing of dc brushless motor and electric motor end cap vehicle can occur and causes when jolting in the process of moving the phenomenon of electric machine casing and motor front end cover cracking to occur; The limitation that the length of while motor lines also makes the connection of motor lines be subject to.In addition, original radiating ribs is the straight line plane, and radiating effect is not good.
The utility model content
The utility model provides a kind of limitation problem that parts ftracture and motor lines length is subject to and dc brushless motor with good radiating effect of solving.
For solving the problems of the technologies described above, the utility model dc brushless motor comprises: electric machine casing; Motor front end cover is provided with fixing hole at the edge of described motor front end cover, and described motor front end cover is connected with described electric machine casing via described fixing hole by bolt; Terminal box, described set of terminal box are on described electric machine casing, and described terminal box is connected with motor lines; And radiating ribs, described radiating ribs is arranged on the outside of described electric machine casing.Described radiating ribs is wavy surface.
The utility model dc brushless motor has increased screw hole is fixed together two parts (motor front end cover and electric machine casing) it better, does not cause when jolting in the process of moving the phenomenon of electric machine casing and motor front end cover cracking to occur thereby vehicle can not occur; Simultaneously, increase the limitation that length that a terminal box solved motor lines is subject to; In addition, original radiating ribs is changed into the face of wave by the straight line plane, solved the problem of motor radiating.The utility model dc brushless motor has increased the reliability of motor, has reduced greatly the failure rate of motor.

Embodiment
Below in conjunction with accompanying drawing, the utility model dc brushless motor is described in further detail.
As shown in Figure 1 and Figure 2, the utility model dc brushless motor comprises: electric machine casing 1; Motor front end cover 2 is provided with fixing hole 3 at the edge of motor front end cover 2, and motor front end cover 2 is connected with electric machine casing 1 via fixing hole 3 by bolt; Terminal box 4, terminal box 4 are arranged on electric machine casing 1, and terminal box 4 is connected with motor lines; And radiating ribs 5, radiating ribs 5 is arranged on the outside of electric machine casing 1.Radiating ribs 5 is wavy surface.
The utility model dc brushless motor has increased screw hole is fixed together two parts (motor front end cover and electric machine casing) it better, does not cause when jolting in the process of moving the phenomenon of electric machine casing and motor front end cover cracking to occur thereby vehicle can not occur; Simultaneously, increase the limitation that length that a terminal box solved motor lines is subject to; In addition, original radiating ribs is changed into the face of wave by the straight line plane, solved the problem of motor radiating.The utility model dc brushless motor has increased the reliability of motor, has reduced greatly the failure rate of motor.
The preferred embodiment of below the utility model having been created illustrates, but the utility model is created and is not limited to described embodiment, those of ordinary skill in the art also can make all modification that is equal to or replacement under the prerequisite of the utility model creative spirit, the modification that these are equal to or replacement all are included in the application's claim limited range.
