1. Especially interesting and difficult to understand is the role of cross-field currents . 2. Direct-current motors allow for changes of speed by adjusting the shunt field current . 3. For generators, the field current is smaller than the output current. 4. Each was then controlled by manually adjusting the field current . 5. An automatic voltage control device controls the field current to keep output voltage constant. 6. The wire supplying the field current is often referred to as the " exciter " wire. 7. The LP may field current provisional legislator Ho Sai-chu and Provisional Urban Councillor Tommy Cheung Yu-yan. 8. Doak led the fields current site. 9. The locomotive had six slip control, whilst the thyristor bridge is used to invert the field current polarity. 10. Decoupled torque and field currents can thus be derived from raw stator current inputs for control algorithm development.
