Answer the following statement(s) true (T) or false (F)
1. The winding of a three-phase, squirrel-cage induction motor is made of formed coils that are connected to give three single-phase windings spaced 60 electrical degrees apart. 2. Some types of squirrel-cage induction motors are smaller than others and have aluminum end rings that are cast in one piece. 3. At start-up, all of the resistance of the wye-connected speed controller is inserted in the rotor circuit. 4. The stator leads of a three-phase, wound-rotor induction motor are marked M1, M2, and M3. 5. The wound-rotor motor and the squirrel-cage motor have the same percent efficiency, power factor, percent slip, speed, and torque characteristics.
