Same or similar element or element with the same or similar functions are indicated to same or similar label eventually.Below by ginseng
The embodiment for examining attached drawing description is exemplary, it is intended to for explaining the utility model, and should not be understood as to the utility model
Limitation.
Such as Fig. 1 and Fig. 2, according to the end cap 1 of the motor 100 of the utility model embodiment, the end cap 1 is positioned including bearing
Portion 11, end cap mounting portion 12 and reinforcement structure 13, wherein bearing positioning region 11 can be used for placing bearing or be used as his way, end
End cap 1 can be installed on the field frame assembly of motor 100 or be used as his way by lid mounting portion 12, and reinforcement structure 13 can be by bearing
Positioning region 11 is connected together with end cap mounting portion.
Wherein, end cap mounting portion 12 include surround bearing positioning region 11 axis it is spaced multiple, in other words, end cap
Mounting portion 12 include it is multiple, and multiple end cap mounting portions 12 along around bearing positioning region 11 direction along be intervally arranged it is more
It is a.Multiple end cap mounting portions 12 can be set on the same plane of the axis perpendicular to bearing positioning region 11；Multiple end cap peaces
Dress portion 12 can also be not provided with on the same plane of the axis of vertical bearing positioning region 11；Multiple end cap mounting portions 12 and bearing
Positioning region 11 can be set on the same plane of the axis perpendicular to bearing positioning region 11；Multiple end cap mounting portions 12 and bearing
Positioning region 11 can also be not provided with on the same plane of the axis of vertical bearing positioning region 11.Each end cap mounting portion 12 and axis
It holds and is respectively connected with reinforcement structure 13 between positioning region 11, connected end cap mounting portion 12 and bearing positioning region 11 by reinforcement structure 13
It is connected to together.Multiple reinforcement structures 13 have gap on the direction around bearing positioning region 11, that is to say, that multiple reinforcement knots
Structure 13 can be connected directly or not be connected directly, it is only necessary to guarantees between multiple reinforcement structures 13 there are gap, these
Gap can be used to radiate to motor 100, or as the resigning etc. to other structures.
In addition, reinforcement structure 13 includes connecting plate 131, the first reinforcing rib 132 in some embodiments of the utility model
With the second reinforcing rib 133, the first reinforcing rib 132 and the second reinforcing rib 133 are connected to connecting plate 131 in a first direction on M
Opposite two sides, connecting plate 131 are equipped with heat release hole 134, and heat release hole 134 penetrates through connecting plate 131 in a second direction, and first adds
Third reinforcing rib 135 is connected between strengthening tendons 132, the second reinforcing rib 133 and connecting plate 131.First direction is around bearing
