DC Motor Operation Summary
Starting resistors are necessary for large DC motors to prevent
damage due to high currents while starting the motor.
Starting resistors are placed in the starting circuits for the
controllers that start the motor. When the motor reaches full
speed, the starting resistors are cut out of the circuit.
The four nameplate ratings for a DC motor include:
-
voltage
-
current
-
speed
-
power
