Abstract
The name of the utility model is integrated double motor, relating to various industrial fields such as petroleum, mine, steel, cement, etc. a plurality of apparatuses have heavy load at the time of starting, so these apparatuses must be collocated with a motor with relatively high power. However, after starting, the load becomes small, and the output power of the motor also becomes small. In this way, the efficiency and the power factor of the motor are both low, resulting in serious waste of energy resources. The integrated double motor adopted, two motors operate at the time of starting, guaranteeing that the starting moment of force is large enough. However, at the time of normal operation, one motor stops, and the other motor runs alone. Accordingly, the efficiency and the power factor of the motor are both considerably enhanced, thus saving energy resources.
Description
Technical field
The utility model relates to various industrial circles such as oil, mine, iron and steel, cement.
Background technology
At various industrial circles such as oil, mine, iron and steel, cement, the load when starting of considerable equipment is very heavy, must dispose than high power motor, but enter in the normal operation after the starting, load reduces again, output power of motor just reduces thereupon, and its load often is lower than below 50% of rated power.Like this, the efficient of motor and power factor are all very low, cause energy waste serious.
Summary of the invention
Be energy savings, improve the efficient and the power factor of motor, requiring on the equipment that starting power is big, running power is low, adopt two-shipper to drag, promptly the coaxial connection of motor of two equal-wattages or different capacity.When starting, the two-shipper running guarantees to have enough big starting torque, and after changing normal operation, load over to and reducing, a motor stops, and another motor unit turns round.Like this, under appropriate design two-shipper power situation, the load factor of operated motor can be near fully loaded, and efficient and power factor all can greatly improve, thus energy savings.
Two three-phase alternating-current motors of coaxial connection because complexity is installed, require the concentricity height, and axial dimension is big, so specialized designs is manufactured a kind of " whole bi-motor ", promptly in a shell, two cover stators are set, coaxial birotor.
Description of drawings
Fig. 1 is a standard three-phase alternating-current motor structural representation.
Fig. 2 is whole bi-motor structural representation.
1,2 cage rotors, 3 stator cores, 4 casings, 5 coil windings, 6 fan guards, 7 fans, 8 rear end caps, 9 rear bearings, 10 front end housings, 11 fore bearings among the figure.
Embodiment
With reference to Fig. 2.Press common electric machine and make common process, in casing 4, press-fit two cover stator cores 3, coiling two cover coil windings 5 in its wire casing unshakable in one's determination.On axle 1, press-fit two cage rotors 2, hot charging front and back bearings 11 and 9.The axle 1 that will press-fit two cage rotors 2, the good front and back bearings 11 of hot charging and 9 penetrates in the casing 4 that has press-fited stator core 3 and wound coil windings 5.On axle 1 two ends front and back bearings 11 and 9, be pressed into front and rear cover 10 and 8 again,,, axle 1 can be rotated under the support of front and back bearings 11 and 9 with the gap that keeps designing between cage rotor 2 and the stator core 3 simultaneously with casing 4 fastening location.At the tail end of axle 1 fan 7 and fan guard 6 are installed at last, are promptly finished the assembly of whole bi-motor.
Claims (1)
1. whole bi-motor, form by same casing, two cover stators, coaxial birotor, soon two three-phase alternating-current motors design, manufacture as a whole, it is characterized in that, identical with component structurals such as common three-phase alternating-current motor stator, axle, rotors, manufacturing process routinely, difference is for press-fiting two cover stator cores in same casing, coiling two cover coil windings press-fit two cage rotors simultaneously on an axle in its wire casing unshakable in one's determination, are assembled into a whole bi-motor afterwards.
