Abstract
The utility model relates to a stepless speed regulating induction motor, which is composed of a machine base and a compound rotor. The utility model is characterized in that a stator can move in the machine base along the axial direction, a rotary rotor is fixed along the axial direction, so that the relative position of the stator and the rotor along the axial direction can be changed to change the electromagnetic moment of the motor, and thus the stepless speed regulation is achieved. The motor can achieve stepless speed regulation without additional equipment. The utility model has the advantages of simple structure, reliable running, large speed regulating range, no distortion of the wave shapes of the electric voltage and electric current, etc. The utility model is suitable for blowers and water pumps with the power of under 100KW.
Description
The utility model relates to a kind of stepless speed regulation induction motor.
Pump machines equipment such as blower fan water pump occupy critical role in industrial and agricultural production, its total power consumption accounts for about 31% of national commercial power total amount, its year, power consumption accounted for national gross generation about 40%, and therefore implementation is energy-conservation, significant on blower fan, mechanical water pump equipment.The drive motors of blower fan water pump generally can not speed governing at present.General motor has only a small amount of blower fan water pump to adopt governor controlled motor.Successful mode of speed regulation has variable voltage control, pole changing, frequency control, chopping regulating speed, tandem control and electromagnetic speed-adjusting.It is by changing internal structure of motor, reach the speed governing purpose, yet pole changing is step speed regulation that pole changing is only arranged in these modes of speed regulation, and rotating speed can not continuous control, thereby the scope of application is restricted.And alternate manner all will add other device and carries out speed governing, and the price of these speed regulating device also all is with capacity motor 3-10 doubly, and their reliability depends on the reliability of these devices to a great extent.
It is a kind of simple in structure, reliable that the purpose of this utility model is to provide, and need not additional miscellaneous equipment and carry out the stepless speed regulation induction motor.
The utility model is realized as follows, as shown in drawings, the architectural feature of this asynchronous machine is by mechanical driving device stator to be moved vertically, rotor rotated is motionless vertically, the relative axial position of stator and rotor is changed, change the electromagnetic torque of motor like this, realized the purpose of speed governing.Primary structure is as follows: by stator ［ 3 ］, and composite rotors ［ 1,2 ］, rotating shaft ［ 11 ］, stator core lining ［ 4 ］, support ［ 5 ］ and mechanical driving device ［ 6,7,8,10 ］ are formed.Composite rotors is made up of a main rotor ［ 2 ］ and a pair rotor ［ 1 ］, and main rotor ［ 2 ］ is cage rotor or wound rotor, pays rotor ［ 1 ］ by the mechanical property design.Stator core lining ［ 4 ］ connects together with interference fit with stator core ［ 3 ］, and stator winding ［ 9 ］ constitutes stator with stator core.Stator core lining ［ 4 ］ is slidingly matched vertically with support ［ 5 ］.Slide block ［ 7 ］ uses screw and key and stator core lining ［ 4 ］ to form one, and slide block ［ 7 ］ has screw thread to cooperate with leading screw ［ 8 ］.Leading screw ［ 8 ］ cooperates for rolling with support ［ 10 ］.Support ［ 10 ］ forms one with screw and support ［ 5 ］.Handle control leading screw ［ 8 ］ rotates, by the threaded engagement relation slide block ［ 7 ］ is moved vertically, and then it is mobile vertically to drive stator ［ 3 ］, cause the stator ［ 3 ］ and the coupling unit of main rotor ［ 2 ］ to change, the magnetic flux size that promptly enters main rotor ［ 2 ］ changes, the electromagnetic torque of motor is changed, realize stepless speed regulation.
The mobile stator motor with stepless speed regulation that the utility model provides is simple in structure, processing and manufacturing, and convenient operating maintenance, reliable.Its cost is all lower than existing other stepless speed-regulating device, only is about 1.5 times with capacity motor price, when being used to drive the following energy saving in fans and pumps operation of 100KW, and small investment, instant effect.This motor speed adjusting scope is big, and being used for its rotating speed of blower fan water pump load can down regulate arbitrarily from rated speed.The voltage of this motor, electric current are sinusoidal wave, undistorted, and be pollution-free to electrical network.Be specially adapted to the following blower fan of 100KW, pump-type load needs the occasion of variable speed energy saving.
