Description

Motor base

Technical field

The present invention is about a kind of motor base, and especially a kind of supplying in conjunction with coil groups and rotor is whereby to constitute the motor base of motor configuration.

Background technology

Please refer to shown in Figure 1ly, existing motor 9 roughly comprises a motor base 91, a rotor 92 and a coil groups 93.This motor base 91 has a base plate 911, and a surface of this base plate 911 forms an axle bed 912, and this axle bed 912 can supply in conjunction with a central siphon 913; This rotor 92 is rotatably in conjunction with central siphon 913; This coil groups 93 is in conjunction with this motor base 91, in order to drive this rotor 92 rotary works.

The axle bed 912 of above-mentioned this motor base 91 is mainly in order to supporting this central siphon 913, and this central siphon 913 must be in order to support as rotor 92 members such as grade; Therefore, can this axle bed 912 support this central siphon 913 really, is the key factor of the product quality that influences this motor 9.More in detail, this central siphon 913 axially on, this base plate 911 has an axial thickness T, 912 of this axle beds have an axial height H; Wherein can this axial thickness T and this axial height H proportion structure relation each other will determine this axle bed 912 support this central siphon 913 really, for example:

As shown in Figure 2, when supposing that the axial height H of this axle bed 912 is low, then this axle bed 912 and the also relative minimizing of this central siphon 913 bonded area each other; Therefore, this axle bed 912 can't be supported this central siphon 913 effectively, causes this central siphon 913 to be easy to generate problems such as deflection and linking steady character be not good.

And for example shown in Figure 3, when supposing that the axial height H of this axle bed 912 is higher, though this axle bed 912 and relative the increasing of this central siphon 913 bonded area each other, can make this axle bed 912 effectively support this central siphon 913 of ground, yet, at this moment, the axial thickness T of supposing this base plate 911 does not increase relatively, then cause this base plate 911 to fail firmly to support this axle bed 912 on the contrary, cause this base plate 911 and the junction of this axle bed 912 to be easy to generate the crack, and then influence the structural strength of this motor base 91; Moreover, if this axial height H sets when too high, also can increase the whole axial height of this motor base 91 relatively, and be difficult for towards microminiaturized direction research and development design.

In sum, the axial height H of the axial thickness T of this base plate 911 and this axle bed 912 structure proportion relation each other, for causing this central siphon 913 whether to produce deflection and linking steady character is not good, or the structural strength that influences this motor base 91 key factor such as conformance with standard whether, therefore, necessaryly improve at existing motor base 91.

Summary of the invention

The purpose of this invention is to provide a kind of difficult motor base that produces deflection of central siphon of guaranteeing.

Another object of the present invention provides a kind of central siphon that makes can be firmly in conjunction with motor base.

Another purpose of the present invention provides a kind of motor base that promotes structural strength.

For reaching aforementioned goal of the invention, the technology contents that the present invention used is as follows:

A kind of motor base comprises a base plate, an axle bed and a central siphon.This base plate has a relative first surface and a second surface, and this first surface to second surface has an axial width; This axle bed is arranged at the second surface of this base plate, this axle bed has one first relative end and one second end, this first end is towards this base plate, this second end is away from this base plate, the end face of this second end has an axial height to the first surface of this base plate, and the ratio of this axial height and this axial width is 1.5～5; This central siphon is in conjunction with this axle bed.

Beneficial effect of the present invention is: the base plate of motor base has axial width, axle bed has axial height, and the ratio of this axial height and this axial width is 1.5～5, whereby, after guaranteeing that this central siphon and this axle bed mutually combine, can promote this central siphon and this axle bed linking steady character each other, and avoid this central siphon to produce situations such as deflection; Moreover the junction that can effectively prevent this base plate and this axle bed of also holding concurrently produces the crack, guarantees that motor axle bed of the present invention has preferable structural strength.The present invention also can be applicable to motor configuration or radiator fan, and with many effects such as structural strength of guaranteeing that central siphon is difficult for producing deflection, lift shaft pipe jointing steadiness and promotes motor base.
