As shown in figure "B" of the illustration, what does the M-G set's three-phase drive motor mechanically drive? EL-0101

Correct Answer: Option A — the DC generator armature

In a Ward-Leonard motor-generator set, the AC drive motor is mechanically coupled to the shaft of the DC generator. The AC motor rotates the DC generator armature at a constant speed within its magnetic field, generating adjustable DC voltage to control the main propulsion or winch motor.
