Question 1 of 270705eccefa4bacbc34ba4d48218

Low horsepower, polyphase, induction motors can be started with full voltage by means of which kind of starter?

Question 1 of 27070

Low horsepower, polyphase, induction motors can be started with full voltage by means of which kind of starter?

🔍 Key Concepts

• Full-voltage starting of induction motors • Differences between reduced-voltage starters (compensator, auto-transformer, primary-resistor) and direct-on-line methods • Effect of motor horsepower on the choice of starter type

💭 Think About

• Which starter type applies line voltage directly to the motor terminals without intentionally reducing it at start? • Why might low-horsepower motors be allowed a simpler starting method than large motors, in terms of inrush current and system impact? • Among the listed starter types, which ones are specifically designed to reduce starting voltage or current?

✅ Before You Answer

• Identify which starters are reduced-voltage devices by design. • Check which option corresponds to applying full line voltage directly to the motor from rest. • Confirm that low horsepower motors generally can tolerate high inrush current without needing a complex starter.
