Description

Electric machine

Technical Field

The utility model relates to a motor.

Background

At present, the requirements on the volume and the protection of the motor for the forklift and the aerial work platform are more and more strict, the requirement on the volume is small, the protection grade is increasingly improved, the requirement on the design of the motor is that the internal space must be fully utilized and the protection requirement is met, however, the electromagnetic wire of the motor is usually thick and hard and is not easy to bend, and the electromagnetic wire is easy to damage or scratch. Therefore, the space design of the internal wiring and related parts of the motor is very important for protecting the electromagnetic wire from being damaged.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a not fragile electromagnetic wire's motor.

The purpose of the utility model is realized like this:

the utility model provides a motor, includes casing, stator winding and end cover, and stator winding sets up in the casing, and the end cover lid is served at casing one, be equipped with the annular in the end cover and hold the chamber, be equipped with a plurality of fretwork positions on the axial of end cover, the fretwork position holds the chamber intercommunication with the annular, and the footpath of end cover is equipped with a plurality of wire holes, and the wire hole holds the chamber intercommunication with the annular.

The purpose of the utility model can also adopt the following technical measures to solve:

more specific technical scheme, the end cover includes outer loop leg and inner ring leg, connects through a plurality of support arms between outer loop leg and the inner ring leg, and the inner ring leg forms the bearing installation cavity, and the space constitutes between outer loop leg and the inner ring leg the annular holds the chamber, and the space between the support arm constitutes fretwork position.

The electromagnetic wire of the stator winding is led out towards the hollow part along the axial direction and then is bent to be placed in the annular cavity along the circumferential direction of the end cover.

The outlet holes are staggered with the leading-out ends of the electromagnetic wires of the stator winding.

And a cable fixing head is arranged on the wire outlet hole.

The utility model has the advantages of simple structure and reasonable design, the electromagnetic wire of stator winding is convenient for at the fretwork position is worn out and is placed in the annular and hold the intracavity, the cable conductor and the electromagnetic wire of still being convenient for outside press-fit in the annular appearance chamber, avoid the cable conductor overlength to lead to the problem of unable connection, still reduce the bending degree at electromagnetic wire bending position, the protection electromagnetic wire does not receive the damage, the end of drawing forth of wire hole and electromagnetic wire staggers, it is crooked too big and can't draw forth when the cable conductor penetrates the annular appearance chamber from the wire hole to prevent to appear, cable fixing head protection cable conductor and improvement motor protection level.

Detailed Description

The present invention will be further explained with reference to the drawings and examples.

In a first embodiment, as shown in fig. 1 to 4, a motor includes a casing 1, a stator winding 2 and an end cover 3, the stator winding 2 is disposed in the casing 1, the end cover 3 includes an outer circumferential wall 31 and an inner circumferential wall 32, the outer circumferential wall 31 and the inner circumferential wall 32 are connected by a plurality of support arms 33, the inner circumferential wall 32 forms a bearing installation cavity 34, a space between the outer circumferential wall 31 and the inner circumferential wall 32 forms an annular cavity 35, a gap between the support arms 33 forms a hollow portion 30, the hollow portion 30 is communicated with the annular cavity 35, three wire outlets 36 are radially disposed on the end cover 3, cable fixing heads are disposed on the wire outlets 36, and the wire outlets 36 are communicated with the annular cavity 35. The end cap 3 is covered on one end of the housing 1 by a peripheral wall 31.

In this embodiment, the position of the wire outlet hole 36 and the position of the leading-out end of the electromagnetic wire 21 of the stator winding 2 are opposite to each other with respect to the central axis of the motor, and the cable fixing head 37 is disposed on the wire outlet hole 36. Furthermore, since the arm 33 also avoids the position of the wire outlet hole 36 and the position of the leading end of the magnet wire 21, the area of the hollow portion 30 corresponding to the positions of the wire outlet hole 36 and the leading end of the magnet wire 21 is larger than that of the other hollow portions 30.

The electromagnetic wire 21 of the stator winding 2 is led out towards the hollowed-out part 30 along the axial direction, and then is bent to be placed in the annular containing cavity 35 along the circumferential direction of the end cover 3, the cable fixing head 37 is fixed on the wire outlet hole 36, the inner terminal of the external cable 4 penetrates through the cable fixing head 37 and is bent in the annular containing cavity 35, and the electromagnetic wire 21 of the stator winding 2 and the inner terminal of the cable 4 are in compression joint in the annular containing cavity 35 through the insulating sleeve.
