Flywheel-type motor for diesel engine

Abstract

The invention proposes a flywheel-type motor for a diesel engine. The flywheel-type motor comprises a crank shaft, excitation windings, a stator iron core, armature windings and a rotor iron core, wherein 2N rotor poles with circular fan-shaped bulges are arranged on the inner side end surface of a round disc of the rotor iron core, 3N stator poles with circular fan-shaped bulges are uniformly arranged on the end surface, opposite to the end surface of each stator pole, of the stator iron core, the stator iron core is provided with a groove among each three stator poles, the excitation coil is wound in the groove and wound around the three stator poles, the winding directions of adjacent excitation coils are opposite, each stator pole is provided with the one of the armature coils wound around an axial direction, an armature winding is divided into three phases, and each phase of the armature coil comprises the same-phase armature coil. By the flywheel-type motor, the size of a gap magnetic field is adjusted by adjusting the size of an excitation current, and thus, stable output voltage can be maintained on the condition of variable load and variable rotational speed of the motor.

Description

technical field [0001] The invention relates to a flywheel motor for a diesel engine, which belongs to the field of special motors. Background technique [0002] Micromachines have the characteristics of good mobility, convenient use and transfer. As a green engine, the diesel engine has the disadvantages of large volume and heavy weight, which restrict its application in many places. Therefore, the miniaturization of diesel engines has attracted widespread attention. With the development of motor technology, compact flywheel motors are applied to various engines. [0003] The flywheel motor can be installed directly on the crankshaft between the engine and the gearbox, or directly in the flywheel of the diesel engine. The volume of the engine can be significantly reduced through this compact installation method. Therefore, in the present invention, the flywheel motor is applied to the diesel engine, and at the same time, the flywheel motor in the present invention can b...
