Problems solved by technology

[0002] At present, the tachometer generators in the prior art generally adopt a combined structure, that is, a brushless motor and a brushed tachometer generator are generally combined to form a tachometer generator set, or a brushless motor and an alternator are combined to form a tachometer generator set. The tachogenerator set with a combined structure has the disadvantages of short service life and sparks and interference because the former uses a brushed tachogenerator; while the latter because the output voltage of its alternator cannot reflect the direction of rotation, It is necessary to add an additional turn signal, so there is a defect that the structure is more complicated, and the working performance is not stable.
[0003] point; in addition, the existing combined structure tachogenerator sets still have the problems of large volume and high production cost

Embodiment Construction

[0017] Embodiments of the present invention: the integrated brushless DC tachogenerator can be made by embedding the motor winding and the tachogenerator winding in the stator core slot of the brushless DC motor, so that the brushless DC motor and the brushless DC Both tachogenerators share the same stator core, the same rotor and the same main pole excitation magnet steel.

[0018] When adopting the method of the present invention to make an integrated brushless DC tachogenerator, an existing brushless DC motor provided with a stator core 5 and a rotor 6 can be used to make it, and its brushless DC motor can adopt 4 pairs of poles, 24 groove structure, making

[0019] At the same time, install the main pole magnetic steel 7 on the rotor 6 according to the traditional method, and then put the motor winding 1 and the tachogenerator winding 3 in the slot of the stator core 5 of the brushless DC motor. When the motor winding 1 and the tachogenerator winding 3 are embedded in the...
