Abstract
The invention relates to a motor double-rotor structure device, rotors are fixedly arranged on a spindle, a double-rotor structure is arranged in a casing, and two rotors are respectively arranged and fixed on a rotation axis. The axes of the two rotors are in the same axial line, the two rotors are respectively arranged on both sides of a stator, and a magnet content is fixed on a corresponding surface of the double-rotor and the stator is fixed on the casing. The utility model has no magnetic braking torque caused by a constant magnetic field, and a starting device is not additionally arranged on the motor, therefore, the starting current exerts less influence on the fluctuation of a power system, which enhances the starting load. A brushless direct current motor can reduce the starting working current and an alternating current generator can reduce the starting working energy; therefore, the utility model has the technical effect of energy conservation and improving efficiency. The utility model can be suitable for the synchronous alternating current motors, the brushless direct current motors and at the same time the alternating current generators, which can be popularized and used widely.
Description
Affiliated field: the utility model relates to a kind of electric machine, particularly a kind of double-rotor structural apparatus for motor.
Background technology: synchronous AC motor adopts single rotor structure, on rotor, install permanent magnetic material additional or electric magnet exciting coil is housed, because the magnetic brake torque that permanent magnetic material and the formed stationary magnetic field of electric magnet exciting coil are produced, motor does not almost have the self-starting ability, need install starting device additional, and it is big that starting current influences power network fluctuation, and starting duty is little.DC Brushless Motor adopts single rotor structure, installs permanent magnetic material additional and form magnetic pole on rotor.In order to overcome the magnetic brake torque that the stationary magnetic field produced that magnetic pole forms, need to increase the energy (power) that starts to work.Alternating current generator adopts single rotor structure, installs permanent magnetic material additional or electric magnet exciting coil is housed on rotor, forms magnetic pole.For the magnetic brake torque that the stationary magnetic field produced that will overcome magnetic pole formation need increase the energy that starts to work (power).
Summary of the invention: it is little that the purpose of this utility model provides a kind of starting duty, the double-rotor structural apparatus for motor of energy savings.The purpose of this utility model realizes by following structure: the utility model is a kind of double-rotor structural apparatus for motor, fixedly mounting rotor on the main shaft,: dual-rotor structure is installed in the casing, two rotors are fixed on the rotating shaft respectively, the birotor axle is positioned on the same axial line, birotor places the both sides of stator respectively, is fixing on the two-spool corresponding surface to contain magnet, and stator is fixed on the casing.Between the birotor of the present utility model under the effect in this machine, magnetic field, form the stationary magnetic field, the birotor run-in synchronism under the pining down of stationary magnetic field that divides shaft device, material in birotor intermediate stator, stator yoke is non magnetic, there is not the magnetic brake torque between rotor and the stator, the stationary magnetic field that the rotating magnetic field that stator coils of motor produces directly promoted and affected rotor, and then drive the rotating magnetic field operation of birotor with stator coil, the stationary magnetic field that produces between the birotor magnetic pole on the generator by outer powered rotate, the cutting stator coil generates electricity.The utility model is owing to adopt double-rotor structural apparatus, the magnetic brake torque that does not have the stationary magnetic field and produced adopts double-rotor structural apparatus to make synchronous machine can rely on self-starting, need not to install additional starting device, starting current is little to the influence of power network fluctuation, increases starting duty.Dc brushless motor can reduce starting current.Alternating current generator can reduce the energy that starts to work (power), so the utility model can play the technique effect of energy efficiency.The magnet that contains of the present utility model can adopt permanent magnet, perhaps adopts electric excitation device.The utility model goes for synchronous AC motor, DC Brushless Motor, also is applicable to alternating current generator simultaneously, can extensively promote the use of.
