Abstract
The utility model provides a power generator rotor, in which an iron core 2 is pressedly arranged on a rotor axle 1 and which is characterized in that a wiring groove 3 of the iron core 2 has an included angle relative to the axial lead of the rotor axle 1. The output voltage waveform of the utility model is close to sine wave, thereby greatly improving the stability of the output voltage, and is beneficial to prolong the life of electric appliance, furthermore, the structure is simplified and the cost is reduced.
Description
One, technical field:
The utility model relates to a kind of generator amature, in particular for the power consumption equipment of field work and the generator amature of illumination, family expenses and Internet bar's emergency power supply.
Two, background technology:
Existing brushless generator rotor is the straight trough structure, the wiring groove that is the ingot rotor is parallel to generator output shaft axial line, its shortcoming is that generator electricity waveform is very poor, indentation, irregularity of wave form is between 15%～25%, and the component of triple-frequency harmonics and quintuple harmonics is very heavy in the waveform, thereby to consuming device, particularly the impact of capacitive load is very big, causes the damage in advance of consuming device.And to embed two magnet steel excitations of N, S on traditional brushless generator rotor, magnet steel adopts machinery to embed usually and solidifies with bonding agent, because magnet steel is hard, crisp, magnet steel cooperates bad with the rotor punching size or undue force when embedding in telescopiny, magnet steel bursts easily and causes waste, if magnet steel inside bursts or is bonding not firm and be not found, in the process of running up, also can cause magnet steel to fly out owing to action of centrifugal force, the ingot rotor airgap is blocked, thus ingot rotor phase mutual friction and cause generator to damage.
Three, summary of the invention:
The purpose of this utility model provides a kind of generator amature, and it is poor to solve existing brushless generator rotor output voltage waveforms, and because of the technical problem that the excitation magnet steel in use breaks down easily must be installed.
Concrete technical scheme of the present utility model is: a kind of generator amature, iron core are fitted on the armature spindle, it is characterized in that: the wiring groove on the iron core has an angle with respect to the armature spindle axial line.
Wiring groove adopts flume structure in the utility model, when starting working, in the rotor in every conductor and the spindle straight trough conductor be certain current potential angle, rotor is in rotary course, the single conductor two ends form certain potential difference, when potential difference reaches certain value, rectification is carried out in the external diode conducting of rotor, produce a fixed magnetic field cutting spindle auxiliary winding, feed back to rotor through capacitor charge and discharge, the exciting current of rotor is increased, go round and begin again, when rotor excitation current reached balance, the spindle main winding was just exported constant voltage.And desirable demagnetization steel also can excitation, thereby has reduced because of the generator failure that the excitation magnet steel causes must be installed.
The utility model has the advantages that: output voltage waveforms has greatly improved the stability of output voltage near sinusoidal wave, helps the consuming device life-time dilatation, and simplifies the structure, and has reduced cost.
