A typical nonservo electric slide uses a reversible motor starter with a thermal overload to protect the motor if the clutch is misadjusted or faulty.

• A. False
• B. True
• C. Not Applicable
• D. Unknown

Answer: (B)

A reversible motor starter with a thermal overload provides both direction control and protection for a nonservo electric slide. When the clutch is misadjusted or faulty, the slide can stall or draw excessive current as the motor tries to move or hold position. That overcurrent heats the motor windings, so the thermal overload trips and disconnects power to prevent damage. This protection is essential in a simple nonservo setup, where there isn’t servo feedback to detect faults, making the overload the key safeguard. So the statement is correct: the thermal overload protects the motor in case the clutch issues cause a jam or stall.
