Background technology

Motor is a kind of conventional power-equipment, and it has a stator and a rotor, and electric energy produces magnetic field during energization, And rotated by magnetic force rotor driven, output torque when rotor rotates.Due to the demand of existing market, some motors need to have The rotation that two motor shafts are rotated and reverse simultaneously, it is real that existing mode can only rely on two independent motors Existing, this mechanism space is also larger, because the requirement in space can not use in many components；In the market also has using two Nested type assembles the motor to be formed inside and outside root motor shaft, and assembling two motor shafts of formation, radial force is larger in the running, electricity Arbor is easily damaged, therefore this reforming mode unreasonable structure.Other existing motor generally uses line in configuration The external mode in road, so as to cause the configuration of motor mixed and disorderly.

Utility model content

The defects of existing for existing motor technology, the utility model aim to provide a kind of rational in infrastructure and space-consuming compared with The rational forward and reverse alternating current generator of double rotating shafts of small and configuration.

Therefore, the utility model uses following technical scheme：A kind of forward and reverse alternating current generator of double rotating shafts, it is characterized in that, bag Include insulating disc and turn to opposite upper motor and lower motor, double rotating shafts that the motor casing of upper motor and lower motor is composed of a fixed connection The integrated motor shell of forward and reverse alternating current generator, the upper and lower ends of integrated motor shell set axis hole, the rotating shaft of the upper motor respectively Lower surface open up circular groove, penetrate the circular groove at the top of the rotating shaft of the lower motor, the rotating shaft of lower motor with it is circular Being separated between groove by bearing and supported, the rotating shaft of upper motor is installed on the upper end axis hole of integrated motor shell by bearings, under The rotating shaft of motor is installed on the lower end axis hole of integrated motor shell by bearings；

The insulating disc is fixedly installed in the integrated motor shell inner chamber and described by setting central through hole to be coated at The rotating shaft of lower motor, the rotating shaft of lower motor, which is stretched out outside integrated motor shell parts, is cased with insulating base, described in the rotating shaft face of lower motor Position all fixed covers of insulating base are equipped with conducting slip ring described in the rotating shaft face of the position of the central through hole of insulating disc and lower motor, The rotating shaft of lower motor is provided with axial wire hole, and the both ends aperture of the wire hole is in the position of suit conducting slip ring, wire hole Install adapter cable, the described conducting slip ring of adapter cable two connection；In the insulating disc set with the upper motor and under The switching electric wire of motor conductive communication, input lead is set on the insulating base, all set on the switching electric wire and input lead Conductive contact is equipped with to contact against with the conducting slip ring；Described upper motor and the input ac power of lower motor and described switching Wire electrodes conversely connect.

As the supplement to above-mentioned technical proposal and perfect, the utility model also includes following technical characteristic.

The insulating disc is separated between the motor casing of motor and lower motor and is fixedly connected with two motor casings.

It can reach following beneficial effect using the utility model：The utility model sets two groups to turn surely in electric machine casing Son, and the direction of rotation of two rotors is realized on the contrary, so as to solve one by the power-up sequence of driver control stator coil The problem of two motor shaft rotating rotations of motor.Two motor shafts of the present utility model are supported by bearing fit and connected, and are carried The high stability of two motor shafts rotations.The utility model is occupied little space, rational in infrastructure, and electrical wiring is located in and turned It is motor reasonable integral structure, clean and tidy in axle axis hole, it is adapted to use in less space.
