Description

The iron core-less wound cup-type disk type electric motor rotor

The utility model relates to a kind of iron core-less wound cup-type disk type electric motor rotor, belong to technical field of motors.

Existing market has two kinds, and a kind of is old-fashioned rotor, and it has an iron core, coil is stuck in the iron core slot, and phase changer just is enclosed within on the armature spindle, and defective is that copper consumption is big, and must use silicon steel sheet, complex process, the cost height, service behaviour is also unstable, can produce spark during work, useful life is short, inefficiency, and startability is poor, also having a kind of is new printing wound rotor, it is to be processed into coil with copper sheet, and as the rotor winding, its defective is complex process, and to use special equipment, production efficiency is low, and copper factor is also low, thereby influences the operating efficiency of motor.

The purpose of this utility model is the defective at above-mentioned existence, propose a kind of simple and reasonable for structure, stable performance, technology is easily gone, the iron core-less wound cup-type disk type electric motor rotor of long service life.

Technical solution of the present utility model:

Winding 4 is arranged, winding 4 is to be fixed on the branch fixed heads 3 such as coil, the central authorities of fixed head 3 are installed with a copper sheathing 2, phase changer 1 is enclosed within on the copper sheathing 2, and above-mentioned winding 4 can have 13-41 group coil, and it is corresponding with 13-41 commutation sheet on the phase changer 1, the number of turn N of each group coil, N=12 * M, M is the voltage number in the formula, two taps of each group coil are passed fixed head 3 commutation sheets corresponding with it and are joined.

On the outer surface of winding 4 one deck engineering plastics can be arranged, play a part to strengthen.

Characteristics of the present utility model:

(1) volume is little, and is in light weight;

When (2) at high temperature running up, has the ability of the heavy duty of bearing;

(3) have superior control performance (rotor does not have iron core, and is in light weight, and inertia is little, do not have the influence of inductance, thus have starting, stop, the superior characteristics of response performance such as speed governing);

(4) brush life is long, than raising unshakable in one's determination being arranged more than 2 times;

(5) efficient height is that more than 1.2 times of iron core direct current machine are arranged.

Accompanying drawing 1 is a plan structure schematic diagram of the present utility model.

Accompanying drawing 2 is main TV structure schematic diagrames of the present utility model (one deck engineering plastics are not arranged on the outer surface of winding 4).

Among the figure 1 is branch fixed heads, the 4th such as phase changer, the 2nd, copper sheathing, 3 coils, winding

Embodiment:

Selecting winding 4 for use is 23 groups of coils, voltage 36V, and each organizes turn number N=12 * 36=432, and the commutation sheet on the phase changer 1 is 23, and processing one deck engineering plastics play a part to strengthen on the outer surface of winding 4.Be used for the moped motor, after tested its Specifeca tion speeification:

Rated voltage: DC36V

Rated current: 5/6A

Rated power: 150/180W

Output speed: 174-208r/min

Wheel hub efficient:＞75%

Useful life: 3000h

Speed: 20km/n

Climbing capacity: 7 °

Noise:＜55dB (A)

Weight: 3.5kg

Can find out, the utility model compared with prior art, its property indices is more Stable, reliable, and also have good looking appearance, rational in infrastructure, the efficient height, starting torque is big, Climbing capacity is strong, the advantages such as long service life.

Claims (2)

1, iron core-less wound cup-type disk type electric motor rotor, it is characterized in that winding is arranged (4), winding (4) is to be fixed on the branch fixed heads (3) such as coil, the central authorities of fixed head (3) are installed with a copper sheathing (2), phase changer (1) is enclosed within on the copper sheathing (2), above-mentioned winding (4) has 13-41 group coil, corresponding with 13-41 commutation sheet on the phase changer (1), the number of turn N of each group coil, N=12 * M, M is the voltage number in the formula, and two taps of each group coil are passed fixed head (3) commutation sheet corresponding with it and joined.
