OSTI ID:4296824
An investigation into the use of d-c infection braking on the induction motors used for driving the coarss control arms in DIDO is reported. The application of d-c injection braking is found to improve the response of the coarse control arms by appreciably reducing the amount of overrum encountered in positioning the arms. The d-c infection braking involves the application of d-c to two of the three phase stator windings, the d-c being applied immediately the a-c input is disconnected. Various values of d-c braking current were used and the results are recorded. Phase-reversal braking has also been tried, and although faster acting, it is less attractive because it involves greater complexity. (auth)
