What is the purpose of a motor starter in an elevator system?

• A. To maintain constant voltage
• B. To protect the motor from overloads
• C. To supply electrical power to the elevator
• D. To facilitate remote operation of the elevator

Answer: (B)

The purpose of a motor starter in an elevator system is to protect the motor from overloads. Motor starters serve as an essential component that enables the controlled initiation and stoppage of motor operations, helping to prevent damage that could occur from excessive current draws during startup or operational forces. The starter typically includes protective devices such as overload relays, which monitor the motor's current and will disconnect the motor from the power supply if the current exceeds safe levels for a prolonged period. This protective feature helps to extend the life of the motor by preventing overheating and mechanical failure that could arise from such conditions. While maintaining constant voltage, supplying electrical power, or facilitating remote operation are important functions in an elevator system, they are not the primary function of a motor starter. The motor starter’s main focus is ensuring motor safety and reliability during its operation in various conditions.
