WebJan 15, 2024 · In parallel, it may travel from Line, through T1, T4, T5, and T2 back to Line. Both parallel paths contain two series windings. The total resistance therefore will be equal to the resistance of 1 winding alone. For a 240-volt input, each of the windings will drop 120 volts, since there are two windings in series in each path. High Voltage Wiring A Dahlander motor (also known as a pole changing motor, dual- or two speed-motor) is a type of multispeed three-phase induction motor, in which the speed of the motor is varied by altering the number of poles; this is achieved by altering the wiring connections inside the motor. The motor may have fixed or variable torque depending on the stator winding. It is named after its inventor Robert Dahlander (1870–1935). tristian white
