Dual rotors mixed power composite magnetoelectric machine

Abstract

The invention discloses a birotor combination power magneto inductor comprising inner and outer magneto inductors of radial magnetic structure, which comprise inner motor components formed by a input shaft, a inner rotor armature winding, a iron core of inner rotor, a iron core of outer rotor and a magnet steel of outer rotor; a outer motor components formed by a stator winding, a iron core of stator, a iron core of outer rotor, and a magnet steel of outer rotor. Wherein, the iron core of inner rotor is mounted and rotated on the input shaft; the iron core of stator is mounted on the housing; the iron core and magnet steel of outer rotor have rigid connection and rotate with the output shaft, while they are used by both inner and outer motor to via the coolant enter the cooling channel between the iron core of inner rotor and the input shaft, for cooling the iron core of inner rotor. The invention has lower cost, lower weight, tight structure, and better cooling effect.

Description

technical field [0001] The invention relates to a motor, in particular to a dual-rotor hybrid composite permanent magnet motor. Background technique [0002] There are three types of hybrid powertrains: series, parallel and hybrid. In the series system, the generator converts all the energy from the engine into electrical energy, and then the electric motor converts the electrical energy into mechanical energy to drive the wheels. The advantage is that there is no direct mechanical connection between the engine and the wheels, and the engine can be adjusted to work at a high efficiency point; but After two energy conversions, the actual energy utilization rate is low. The parallel system is based on the traditional transmission structure, plus an electric drive system, which is used for acceleration or assisting when climbing. Its advantage is less energy conversion, but the direct mechanical connection between the engine and the wheels, the engine cannot always be on Work...

Problems solved by technology

The parallel system is based on the traditional transmission structure, plus an electric drive system, which is used for acceleration or assisting when climbing. Its advantage is less energy conversion, but the direct mechanical connection between the engine and the wheels, the engine cannot always be on work efficiently

The ordinary hybrid system divides the power from the engine into two paths of mechanical and electric through a special power distribution device, which can take advantage of the advantages of series and parallel, but the structure is complicated and the cost is high. At the same time, too many gear transmissions will reduce efficiency
