Abstract

The utility model is mainly used in fish farming equipment as a driver for bait throwing equipment and particularly relates to a permanent-magnet direct-current motor. The motor comprises a casing, a front end cover, a rear end cover and a rotating shaft, wherein the two ends of the rotating shaft are fixedly installed together with the front end cover and the rear end cover respectively, the casing is respectively screwed and fixed together with the front end cover and the rear end cover, a rotor assembly is fixed on the rotating shaft and has an odd number of slots, the rear end part of the rotating shaft is fixedly connected with a commutator, an electric brush holder is fixed on the rear end cover, an electric brush is fixedly arranged in the electric brush holder, a magnetic tile is fixed on the inner wall of the casing, and the magnetic tile is designed into an eccentric structure. The permanent-magnet direct-current motor is wide in speed range, long in service life and scientific in structure design. The problem of adaptability to different sites and fish body sizes is completely solved.

Description

Permanent magnet DC motor

Technical field

The utility model is mainly used in doing on fishery cultivating equipment the driving that bait is shed equipment, specifically a kind of permanent magnet DC motor.

Background technology

In the process of shedding at the bait that solves fishery cultivating, cultivation place, fishing body size occur and bait is shed to the different requirements of distance, area, and traditional electric machine speed regulation is unstable, sheds apart from short, shed area little, can not meet the requirement of shedding in large-scale cultivation place.

Utility model content

For the problems referred to above, the utility model provides a kind of wide range speed control, long-life permanent magnet DC motor, and scientific structure design has solved the adaptability to different places, fishing body size thoroughly.

The utility model is achieved through the following technical solutions: a kind of permanent magnet DC motor, comprise casing, front end housing, rear end cap, rotating shaft, described rotating shaft two ends fixedly mount with front end housing, rear end cap respectively, casing connects fixing with front end housing, rear end cap Luo respectively, fixed rotor assembly in described rotating shaft, described rotating shaft rearward end is fixedly connected with commutator, fixed brush frame on described rear end cap, in described brush carrier, fixedly pack brush into, described casing inner wall is magnetic shoe fixedly, and described rotor assembly is odd bin.

As preferably, described magnetic shoe adopts eccentric structure design.

As preferably, on described brush carrier, go back stationary brush cap.

As preferably, fixed electrical machinery insulation cushion on described front end housing.

As preferably, on described casing, arrange and draw plug, the lead-out wire connecting on casing passes from described drawing plug.

The utility model has taked above-mentioned corrective measure to carry out, its beneficial effect is remarkable: adopt this wide range speed control, long-life permanent magnet direct current motor, it adopts odd bin design, stator magnetic shoe adopts eccentric design, make shedding of bait regulate the rotating speed of motor just can reach different material casting areas according to different cultivation places, fishing body size, motor speed speed governing is stable, adjustable extent is large, and applicability is wide.

Accompanying drawing explanation

Fig. 1 is the cutaway view of the utility model embodiment 1.

In figure, 1 is rear end cap, the 2nd, and brush, the 3rd, brush cap, the 4th, brush carrier, the 5th, commutator, the 6th, rotor assembly, the 7th, magnetic shoe, the 8th, casing, the 9th, front end housing, the 10th, electrical machine insulation pad, the 11st, rotating shaft, the 12nd, draw plug, the 13rd, lead-out wire.

Embodiment

Contrast accompanying drawing is below further described the utility model in conjunction with the embodiments:

Shown in Fig. 1, a kind of permanent magnet DC motor, comprise casing 8, front end housing 9, rear end cap 1, rotating shaft 11, rotor assembly 6, brush 2, brush carrier 4, commutator 5, magnetic shoe 7, rotating shaft 11 two ends fixedly mount with front end housing 9, rear end cap 1 respectively, casing 8 respectively with front end housing 9, rear end cap 1 Luo connect fixing, fixed electrical machinery insulation cushion 10 on front end housing 9.After casing 8 and front end housing 9, rear end cap 1 Luo connect and fix, portion within it, fixed rotor assembly 6 in rotating shaft 11, rotor assembly 6 is for odd bin designs, and casing 8 inwalls are magnetic shoe 7 fixedly, serve as stator magnetic shoe 7, magnetic shoe 7 adopts eccentric structure design, and rotating shaft 11 rearward end are fixedly connected with commutator 5, fixed brush frame 4 on rear end cap 1, the interior brush 2 that fixedly packs into of described brush carrier 4, goes back stationary brush cap 3 on brush carrier 4.On casing 8, arrange and draw plug 12, the lead-out wire 13 connecting on casing 8 is drawn plug 12 and is passed from this.

The rated power of this motor is 120W, and the rated voltage of work is DC220V, and rated current is less than 0.85A, and its rated speed can reach per minute 2200 ~ 2600 and turn.

What more than enumerate is only specific embodiment of the utility model; obviously; the utility model is not limited to above embodiment, and all distortion that those of ordinary skill in the art can directly derive or associate from the disclosed content of the utility model, all should belong to protection range of the present utility model.
