A.c. motor drive for diesel-electric locomotives
Alternator (6) converts mechanical energy supplied from diesel motor (1) shaft to electrical energy. Voltage regulator (7) calculates the difference between the alternator (6) output voltage and reference voltage value; and by changing the current in the single field winding it keeps output voltage...

| description | Alternator (6) converts mechanical energy supplied from diesel motor (1) shaft to electrical energy. Voltage regulator (7) calculates the difference between the alternator (6) output voltage and reference voltage value; and by changing the current in the single field winding it keeps output voltage of alternator constant. In this way, constant voltage with varying frequency is produced, thus at every shaft speed, power is kept constant. At alternator output (6) there are inductors and capacitors which are selected so as not to drive the circuit to the resonance and at the output there are inverters (11 and 12) which have LC filters for suppressing harmonics. Two individual inverters (11 and 12) drive fan and compressor motors (9 and 10) with three phase alternating current according to the commands produced by master control unit (13). |
