Title: Hybrid alternator with voltage regulator
Inventor: CURTISS WILLIAM P
IPC: H02K1/22
Filed: 1994-06-11
Granted: 2001-05-16
Abstract: A hybrid alternator includes a stator and a rotor, with the rotor having longitudinally separate wound field and permanent magnet rotor portions. A rotor excitation circuit applies a forward polarity to the wound field rotor portion to increase output in a boosting mode at low RPMs and a reverse polarity to decrease output at high RPMs in a bucking mode to maintain a constant voltage output. Alternative embodiments combine a magnetic flux concentrating design for efficient low speed operation with integral strength for high speed capability. Dual voltage output is provided either through dual stator windings or through a voltage converter circuit. Single voltage output is provided using only one stator winding. A three state voltage regulator allows voltage regulation without inducing reverse currents onto the power bus in the lightly loaded or no battery conditions. The regulator has automatic interlocking to automatically turn on and off without risking.

Measure and straightening mechanism, is connected with back side of material-receiving frame, in which, the measure mechanism includes bias and angle measure device, and by matching both to search the bias value and angle of shaft located on material-receiving frame. Then, through computer to record and analyze, to get highest bias value and angle. The straightening mechanism is located on top of fixing position of shaft by vertical way to proceed rectifying, then through software to analyze and judge the straightening amount, to drive servo motor to proceed rectifying. Material-collecting mechanism, is located at back side of measure and straightening mechanism, and has separation mechanism to knock out shaft to material-receiving frame after measuring and straightening, and separately put good and defect product into different material-receiving tanks. Self-learning module function, the software can divide bias amount of shaft into several steps. Each step must give an initial straightening amount. Then, based on the bias amount of pre-straightening shaft, straightening amount of straightening mechanism and bias amount of pro-straightening shaft, to continuously rectify the straightening amount. Which enable the shaft to get real straightness through one measuring and rectifying, to promote the straightening rate and quality. By combining above automatic system, this invention can use to straighten the shaft of general motor, oil-gas pressure cylinder and machine, to effectively short the straightening time and decrease manpower.
