Abstract

The utility model discloses an inner rotor motor chassis, which comprises a circular cylinder body. At least three T-shaped grooves are evenly arranged on the circular cylinder body; heat-radiating fins are arranged on the circular cylinder body; and a mounting bracket which consists of an L-shaped wing panel and a mirror-image L-shaped wing panel is further arranged on the circular cylinder body. The inner rotor motor chassis with the structure is convenient for adjusting positions of motor feet, has good heat-radiating performance, and is suitable for an inner rotor motor.

Description

The inner rotor motor casing

Technical field

The utility model relates to a kind of inner rotor motor casing.

Background technology

Inner rotor motor casing at present commonly used is a circular cylinder body, has following two kinds usually: one, adopt the cast aluminium or the cast iron electric machine casing of die casting or high-pressure casting moulding, two, steel plate rolls motor case.During use, be fixedly mounted on a certain position on the circular cylinder body in order to the motor pin that motor is installed.

The shortcoming that the inner rotor motor casing of said structure exists is: one, because of the motor pin is fixed on the circular cylinder body, can not move easily, make that the motor fixed form is more single, the installation site is inconvenient to regulate; Two, heat dispersion is poor, and electric machine temperature rise is than higher, and electrical machinery life can be lacked relatively; Three, cast aluminium or cast iron electric machine casing die cost are than higher.

The utility model content

The technical problem of the required solution of the utility model is: a kind of inner rotor motor casing that can conveniently regulate motor placement of foot, good heat dispersion performance is provided.

For addressing the above problem, the technical solution adopted in the utility model is: the inner rotor motor casing, comprise circular cylinder body, be characterized in: on circular cylinder body, evenly be provided with at least three T-slots, on circular cylinder body, also be provided with radiating fin, on circular cylinder body, also be provided with the mounting bracket of forming by L type fin and mirror image L type fin.

The further technical scheme of the utility model is: described T-slot is the circumference trisection on circular cylinder body simultaneously and the circumference quartering is arranged.

The beneficial effects of the utility model are: one, the inner rotor motor casing of said structure, the motor pin can be installed in arbitrary T type groove, and can so just can select best motor installation site by regulating the motor placement of foot easily along the position of adjustment motor pin in the T type groove; Two, being provided with radiating fin can increase the motor radiating area, thereby reduces electric machine temperature rise, prolongs motor useful life; Three, be provided with the mounting bracket of forming by L type fin and mirror image L type fin, fixed electrical machinery terminal box or Outgoing Line Unit easily.

Description of drawings

Below in conjunction with accompanying drawing technical scheme described in the utility model is described in further detail.

Fig. 1 is the cross-sectional structure schematic diagram of motor case described in the utility model.

Fig. 2 is the motor case shown in Figure 1 and the mounting structure schematic diagram of motor pin.

Embodiment

Referring to shown in Figure 1, inner rotor motor casing described in the utility model, comprise circular cylinder body 1, circular cylinder body 1 is provided with T-slot 2, T-slot 21, T-slot 22, T-slot 23, T-slot 24, T-slot 25, wherein T-slot 25 and T-slot 21, T-slot 23 is the circumference trisection and arranges, T-slot 25 and T-slot 2, T-slot 22, T-slot 24 is the circumference quartering and arranges, circular cylinder body 1 is provided with radiatingfin 3, on circular cylinder body 1, also be provided with the mounting bracket of forming byL type fin 4 and mirror imageL type fin 41, referring to shown in Figure 2,motor pin 6 is installed in theT type groove 22 by setbolt 5.

The inner rotor motor casing of said structure can adopt the method for stretching or extruded aluminium section to process, and can use according to different design requirement intercepting random lengths.

The inner rotor motor casing of said structure can be installedmotor pin 6 in arbitrary T type groove, go back the position ofscalable motor pin 6 in T type groove simultaneously, so just can select best motor installation site by regulating the motor placement of foot easily.Being provided with radiatingfin 3 can increase the motor radiating area, thereby reduces electric machine temperature rise, prolongs motor useful life.Be provided with the mounting bracket of forming by L type fin and mirror image L type fin, easily fixed electrical machinery terminal box or Outgoing Line Unit.

Claims (2)

1. inner rotor motor casing, comprise circular cylinder body, it is characterized in that: on circular cylinder body, evenly be provided with at least three T-slots, on circular cylinder body, also be provided with radiating fin, on circular cylinder body, also be provided with the mounting bracket of forming by L type fin and mirror image L type fin.

2. according to the described inner rotor motor casing of claim 1, it is characterized in that: described T-slot is the circumference trisection on circular cylinder body simultaneously and the circumference quartering is arranged.
