Description

Motor frame with heat dissipation channel

Technical field

This utility model is related to a kind of motor frame, more particularly to a kind of carries out interior circulation with for radiating airflow The motor frame of venting channels.

Background technology

Motor is a kind of by electromagnetic induction, converts electric energy to the device of kinetic energy.Converting electric energy to the mistake of kinetic energy Cheng Dangzhong, electric current can be turned in the coil in rotor, use generation magnetic effect.But during conducting, can be because coil sheet The resistance included by body so that electric current can be lost (for example, copper loss and iron loss), and then produce unnecessary heat energy.These heat Destruction can be produced to the original paper inside motor, and then affects the running of motor.

Illustrate in greater detail, see also Fig. 1 to Fig. 2, Fig. 1 shows the forward sight perspective of the motor frame of prior art Figure；Fig. 2 shows the A-A profiles of Fig. 1.As illustrated, prior art provides a kind of motor frame PA1, comprising a framework sheet Body PA11 and multiple radiating fin PA12.Frame body PA11 be externally provided with four fin setting units PA111, PA111a, PA111b, PA111c, are provided with two connection path PAT1 between three fin setting units PA111, PA111a, PA111b wherein (here only indicates one of which).Connection path PAT1 has vias inner walls PA112 and a channel outer wall PA113.

Fig. 3 is referred to, Fig. 3 shows that the motor frame of prior art coordinates the operating condition schematic diagram of motor cores component. As illustrated, motor cores component PA2 includes one first fan PA21, one second fan PA22, a stator PA23, a rotor PA24, a drive end bearing bracket PA25 and a backside lid PA26.Rotor heat dissipation channel PAT2 is provided with rotor PA24.First fan PA21 with Second fan PA22 is respectively arranged at the central shaft two ends of rotor PA24.Drive end bearing bracket PA25 and backside lid PA26 lids set and framework sheet The two ends of body PA11 so that the space of a closing is formed in frame body 11.

When motor PA100 in the running, electric energy can produce unnecessary heat energy during being converted into kinetic energy so that in motor The temperature of portion's element is raised.When rotor PA24 operates, the first fan PA21 and the second fan PA22 can drive frame body PA11 inner airs flow, and then produce a radiating airflow PAF.Radiating airflow PAF can be absorbed in rotor heat dissipation channel PAT2 Heat energy, makes heat energy be passed in connection path PAT1 with radiating airflow PAF.By the mode of conduction of heat, can further by Heat energy in connection path PAT1 is transferred to outside connection path PAT1, and loss is to external environment.
