Abstract
The invention relates to an electric motor with variable rated power. The electric motor can keep functioning with the rated power under different working conditions so as to be improved in efficiency. The electric motor with the variable rated power comprises a stator core, a stator coil, a rotor core, a rotor coil, a rotor armature, an electric brush, and a position or magnetic flow signal sensor, and is characterized in that a magnetic field generated by electrifying the stator coil interacts with a magnetic field generated by electrifying the rotor coil to realize the rotation of the electric motor. The electric motor can be adjusted in rotating speed and rotating direction through adjustment of the size and direction of input current.
Description
Technical field
The present invention relates to variable rated power motor.
Background technology
Under different applying working conditions, conventional motors only has a rated power, thus makes motor run under different operating mode cannot to maintain the electric efficiency that higher.The variable rated power motor that the present invention relates to keeps rated power operation when motor can be made to use always, thus improves electric efficiency.
Summary of the invention
The object of the invention is to be that motor runs and the moment can keep rated power under any operating mode.
Realizing method of the present invention is, motor stator adopts three-phase coil winding, and carries out wiring according to certain method, and rotor adopts coil windings, and it carries out coiling according to certain method and is connected on armature.
Accompanying drawing illustrates:
Fig. 1 is the variable rated power motor schematic diagram that the present invention relates to.
It is 1. stator core in figure; 2. be stator coil; 3. be rotor core; 4. be rotor coil; 5. be armature rotor; 6. be brush; 7. be motor housing; 8. be axle head signal transducer.
For simplified illustration, eliminate in figure and describe the irrelevant miscellaneous part such as binding post, controller with content of the present invention.
In conjunction with Figure of description, further describe implementation method of the present invention:
2. the three-phase current (three-phase sine-wave electric current or three-phase square wave electric current can be inputted) of suitable size and frequency is inputted to stator coil.2. stator coil can produce the rotating magnetic field with magnetic pole logarithm.
6. 5. inputted the direct current of suitable size to armature rotor by brush, 4. rotor coil can produce the Motionless electromagnetic field (this field pole logarithm is the same with the magnetic pole logarithm of the rotating magnetic field that 2. stator coil produces) with magnetic pole logarithm.
Axle head signal transducer is moment detection rotor coil field pole position 4. 8., and control stator coil input current sequential 2. and frequency by controller, make rotating magnetic field and fixed magnetic field produce electromagnetic force, and promote fixed magnetic field and move in a circle, thus make electric machine rotation.
Realize becoming rated power method: 4. input the electric current varied in size to rotor coil, 4. rotor coil can produce the magnetic field intensity varied in size, now, 2. corresponding current strength is inputted to stator coil, the magnetic field intensity of the rotating magnetic field making it produce and the magnetic field intensity of fixed magnetic field match, thus realize rated power output; When needs strengthen or reduce rated power, only 4. need 5. input to rotor coil the current strength and frequency (power frequency of input stator coil) that match with stator coil, motor can be made to export different rated power.
4. electric motor starting method a. rotor coil inputs a fixed current, by axle head signal transducer 8. detection rotor field pole position, and 2. inputted the size of current and power frequency that match to stator coil by controller, stator coil is made 2. to produce rotating magnetic field, thus rotating magnetic field drive rotor magnetic field is moved in a circle, make electric motor starting.
2. electric motor starting method b. stator coil inputs the direct current of a fixed size, and now, 2. stator coil produces the steady electromagnetic field that has magnetic pole logarithm, and rotor coil 4. also input dc power, produces a rotor field; This rotor field and stator field produce electromagnetic torque, thus make electric motor starting.
