Answer the following statement(s) true (T) or false (F)
1. The electronic controller of a stepper motor provides timing and sequencing of the motor, but it operates electronically to provide circuit closure.
2. Synchronous Servos rely on induction to supply current and therefore magnetic flux to the rotor.
3. Many manufacturing systems and robotic material handling systems use stepper motors to position controls for fast precision movement.
4. During braking, a braking resistor installed across the converter DC bus can be used to dissipate the excess energy by closing the circuit to the resistor.
5. In a selsyn system, the normally stationary rotors of the induction motors are interconnected so that a manual shift in the rotor position of one machine is accompanied by an electrical rotor shift in the other machine in the same direction and of the same angular displacement as the first unit.
1. TRUE
2. FALSE
3. FALSE
4. TRUE
5. TRUE
