Embodiment
Below in conjunction with specific embodiments content of the present invention is described.
As shown in Figure 1, for motor of the present invention comprises: the rotating shaft 30 being arranged on motor center position, driven the rotor 20 of rotation by rotating shaft 30, and the stator 10 cooperatively interacted with rotor 20.Rotating shaft 30 two ends are provided with bearing 31, and bearing 31 is convenient to rotating shaft 30 and is rotated.Outside motor is being provided with housing 40, and housing 40 pairs of motor internals play a very good protection.It is inner that the important heating parts such as rotor 20, stator 10 are arranged on housing 40, therefore causes the inner local temperature of housing 40 too high, needs to carry out cooling process.
Therefore, have the fin 41 of multiple strip in housing 40 outer setting, fin 41 fully contacts with extraneous air, internal heat is distributed by heat transfer.
As shown in Figure 1, be motor output end on the left of rotating shaft 30 of the present invention, therefore can be called front end by the left of motor, right side is called rear end.Described housing 40 front end is provided with front end housing 50, described housing 40 rear end is provided with rear end cap 60, is provided with long bolt 43 between front end housing 50 and rear end cap 60, front end housing 50 and rear end cap 60 tighten together by long bolt 43.
One end of stator 10 outlet is provided with exit 11, housing 40 is provided with outlet protective sleeve 42, exit 11 is exposed at outside motor through housing 40, is convenient to exit 11 wiring like this.
Motor of the present invention, is also provided with multiple outer fin 61 on outside described rear end cap 60, and outer fin 61 shape is that bar shaped is block, and it is spaced apart to press horizontal homogeneous, the height of outer fin 61 is no more than the outline of rear end cap 60, is so not only convenient to install, and does not take too large space.
