Description

The low rotation speed large torque high-efficiency electric motor

One, technical field

The utility model relates to motor, particularly a kind of low rotation speed large torque high-efficiency electric motor.

Two, background technology

Three traditional different motor contribute for the mankind, but there is the rotating speed height, shortcoming or deficiencies such as moment of torsion is little, efficient is low, power consumption height.

Three, summary of the invention

The purpose of this utility model provides a kind of improvement low rotation speed large torque high-efficiency electric motor, adopts cage rotor and interior magneto dual-rotor structure, the shortcoming or the deficiency that overcome effectively or avoid existing in the above-mentioned prior art.

Low rotation speed large torque high-efficiency electric motor described in the utility model, comprise end cap, housing, bonnet, fan, terminal box, base, rotor and axle and stator, it is characterized in that in the described housing stator being installed, rotor and axle are installed in the stator, and housing end plug is installed on an end of housing, and armature spindle exposes end cap, the other end of housing is equipped with bonnet, on the armature spindle in the bonnet fan is installed, the housing base is equipped with base, and the housing top is equipped with suspension ring.

Axis is laid with the heat radiation groove on the wherein said housing.

The utility model has following advantage compared with prior art:

1, rotating speed is low, moment of torsion is big;

2, friendship rate height, economize on electricity;

3, safe in utilization, the life-span is long.

Four, description of drawings

Fig. 1 is a kind of example structure schematic diagram of the present utility model

Fig. 2 is for pressing schematic side view shown in Figure 1

Five, embodiment:

Consult Fig. 1-Fig. 2, a kind of low rotation speed large torque high-efficiency electric motor comprises end cap 2, housing 3, bonnet 6, terminal box 4, base 8, rotor and axle 1 and stator.In the housing 3 stator is installed, rotor and axle 1 are installed in the stator, and end cap 2 is installed on an end of housing 3, armature spindle 1 exposes end cap, and the other end of housing 3 is equipped with bonnet 6, on the armature spindle 1 in the bonnet 6 fan is installed, housing 3 bases are equipped with base 8, and the housing top is equipped with suspension ring 5.Axis is laid with the heat radiation groove on the housing 3.

During operation, rotor 1 relative stator is with n ₀Rotating speed do synchronous operation with rotating magnetic field.Rotor with respect to stator with the rotating speed rotation of N, its air-gap field that rotates synchronously with formation of rotating magnetic field and interior magnetic assist magnetic field, with the relative velocity cutting rotor winding of Δ n, thereby in the rotor winding, produce induced potential, electric current generation electromagnetic torque, drive load.

Since rotating magnetic field and interior magnet rotor with respect to stator with n ₀Rotating speed rotation, the magnetic field of wife's magnet rotor and stator winding intersecting chain induce induced potential in stator winding, be equivalent to the armature voltage E of synchronous machine ₀So, the induced potential that the stator pack of motor produces.

When wife's magnet rotor existed, it is big that the degree of coupling of air-gap field and rotor winding becomes.So the induced potential that the rotor winding produces when same rotating speed increases, rotor current increases, and electromagnetic torque increases, and when driving same load, the revolutional slip S of motor is just little, the mechanical property hardening.Since less for same load S, the slip power loss is reduced, reducing because of stator current simultaneously, the motor copper loss reduces, and therefore, the total losses of motor reduce, and efficient improves.
