| AC Squirrel Cage Induction Motor Resistor | ||
Commonly known as a "reduced -voltage" or "ballast" resistor, this resistor acts as a voltage divider for soft starting of the motor. Initial information needed for sizing your motor and crane control resistor:

| AC Wound Rotor Induction Motor (Slip Ring Motor) | ||
The resistor is wired into the motor secondary slip rings, where it dissipates torque energy in the form of heat. It also provides "soft starting" as resistance is removed in steps. Initial information needed for sizing your motor and crane control resistor:

| Wye-Delta Closed-Transition Starting | ||
Wye-delta is a reduced-inrush starting method in which 3 phase motor stator coils are initially connected in a wye configuration and switched to delta as the motor's speed increases. The resistor works as a reduced voltage starting resistor by starting a motor at 58% reduced voltage.
