The electromotor is characterized in that the stator is mounted inside the casing, the rotor and the rotor shaft are installed inside the stator, the end cover of the casing is mounted at one end of the casing, the rotor shaft is exposed out of the end cover, the rear cover is installed at the other end of the casing, the fan is mounted on the rotor shaft inside the rear cover, the base is installed at the bottom edge of the casing, and a lifting ring is mounted at the top end of the casing. The electromotor has the advantages of low rotating speed, large torsion, high efficiency, power-saving property, safe use, long service life and the like, and is widely applied to electromotor driving engineering.
Description
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.
Claims (2)
