Abstract

The invention discloses a brushless direct current reluctance starter generator. The generator comprises a three-phase armature winding, an exciting winding, a winding series-parallel switching switch, a stator iron core, a rotor iron core, a shaft, a position sensor, a bridge converter and a controller, wherein armature coils, wound intensively, are wound on each pole of the stator iron core; excitation coils are wound by crossing three stator poles; and the armature coils in the same phase are in series or parallel connection to form a group. According to the starter generator, a reluctance structure is used; no winding is generated on the rotor; the generator is simple in structure and reliable to operate; excitation current can be adjusted to keep stability of output voltage during generating; when the generator is started, the generator rotates by means of a reluctance torque; the armature coils are connected in series; a large starting torque is achieved; the generator is applicable to operation at a low speed; the excitation winding is used for generating a magnetic field during generating; the armature coils are connected in parallel; small armature reaction is generated; and the generator is applicable to operation in a high speed. The brushless direct current reluctance starter generator is very applicable to transport tools comprising vehicles.

Description

technical field [0001] The invention relates to a brushless DC reluctance starter generator, which belongs to the technical field of automobile motors and electric appliances. Background technique [0002] The starter generator can not only be used as a motor to start the engine, but also can be used as a generator to supply power to electrical equipment. It is a key component of new energy-saving vehicles such as hybrid vehicles and idle stop vehicles. With the development of automobile technology, starter generator technology is more and more used in automobiles. [0003] In order to prolong the service life of the starter generator and reduce the electromagnetic interference of the spark generated by the carbon brush, the starter generator should adopt a brushless structure. At present, the motors that can be applied to automobile starter generators mainly include claw pole AC motors, permanent magnet synchronous motors, switched reluctance motors, etc. The claw pole AC...
