The rotor wallboard of the utility model is fixed on a principal axis through a key pin or in the mode of welding. A long countersink screw clamps the stalloy iron cores of the left and the right rotors back to back and the rotors and the wallboard are integrated. The suspended end of each iron core is embedded with an inner and outer gage ring. An enclosure is divided into a left part and a right part, and the peripherical wall bodies of the two parts are integrated through a bolt. The side walls on both ends of the enclosure are arranged on the principal axis through a ball bearing respectively and roll-shaped stator stalloy field yokes are fixed on the side walls on both ends of the enclosure respectively. The head face of the roll-shaped stator stalloy field yoke and the head face of the rotor face to each other with air-gap inbetween and stator windings are wound in the inner hole and on the periphery of the suspended end of the head face of the roll-shaped stator stalloy field yoke.

Description
Technical field
A kind ofly change electric energy the plant equipment of kinetic energy into, belong to electric motors.
Background technology
Existing motor generally is that fixed stator case contains the rotatable rotor main shaft, and induced field each other is the face of cylinder, belongs to radial magnetic field.Its defective is that rotating torque is less relatively, and power consumption is high.
02223297.4 number utility model patent has proposed a kind of " plane inductor motor ", rotating torque is bigger.But this machine has only end face relative a disc rotor and a disk stator, and induced field each other is the plane, belongs to axial magnetic field, and there is an axial magnetic suction in axial magnetic field, has a difficult problem that makes commentaries on classics, stator wiping dish easily.And commentaries on classics, stator diameter are big more, axial magnetic suction is big more, and therefore this planar motor can not be done greatly, can only be small-sized or miniature.
Summary of the invention
The purpose of this utility model provides a kind of birotor coordinated type plane sense induction motor.Accomplish that rotating torque is big, it is low to consume energy, and removes axial magnetic suction, provides possibility for making large-scale combined motor.
Technical scheme is that the rotor wallboard is fixed on the main shaft by key pin or welding method, and the long screw rod of immersing oneself in is clamped the rotor wallboard back-to-back with the silicon sheet core of left and right two rotors and combined as a whole mouse cage ring and outer mouse cage ring in each iron core free end is embedded with; Casing is divided into left and right two parts, two-part periphery wall body and function bolt is fixedly connected, casing two ends sidewall is installed on the main shaft by ball bearing respectively, be fixed with web-like stator silicon steel sheet yoke on it respectively, web-like stator silicon steel sheet yoke end face and rotor end-face face one another and air-gap are arranged, all be wound with stator coil on its free end endoporus and the periphery, the stator coil outlet is connected on the terminal box of the casing outside.
Operation principle is as follows: produce rotating magnetic field respectively after the stator coil energising of two stators, rotating magnetic field is doted on each self-corresponding rotor mouse respectively through air-gap and is induced the rotor rotating magnetic field in the winding, drive two rotors and rotate in the same direction, two rotors form the associating drive main axis rotation of making a concerted effort.
Compared with the prior art, the utility model has following characteristics:
1, eliminate axial magnetic suction, security of operation is steady.
Because two rotors are installed on the rotor wallboard back-to-back, two stators are opposite to axial magnetic suction equal and opposite in direction and the direction that two rotors produce, and cancel each other, and therefore make the rotor steady safety that turns round, and wiping dish accident can not take place.
2, can multi-machine interaction, realize that motor maximizes.
If as one " element ", the rotor wallboard with a plurality of " elements " is fastened on the same main shaft in the key pin mode so, can realize multi-machine interaction, can produce the combined high-power motor with the utility model.
3, rotating torque is big, saves electric energy.
The magnetic field area of existing motor is cylindrical surface area, and cylindrical radius rotates the arm of force exactly.And magnetic field of the present utility model face area is a planar annular, is keeping under the same prerequisite of magnetic field area, and reason human relations radius of the present utility model all is greater than the existing cylindrical radius of motor field.The rotation arm of force of the present utility model be outer shroud, interior ring radius non-linear increment and 1/2, therefore much bigger than the rotation arm of force that has motor now.Onesize electric current will produce the electromagnetic force that equates in identical magnetic field area.Under the condition that electromagnetic force equates, because the rotation arm of force of the present utility model is big, therefore the mechanical rotation moment that produces is bigger than existing motor.Both consumed current are the same, and the utility model has been saved electric energy comparatively speaking.According to theory analysis and derivation, energy-conservation what by the decision of the proportionality coefficient of magnetic field inner and outer rings diameter, the utility model can reach 34% than existing energy saving motor.We once did following test: with the water pump of 9 kilowatts of birotor interlock plane sense induction motors and same 40 meters lifts of 10 kilowatts of common motor driven, result of the test is under the identical condition of electrical current, and water yield of the present utility model is many more than 1/4th.
