🔍 Key Concepts

• Typical starting methods for small three-phase induction motors • Relative cost and complexity of different motor starters • Effect of different starters on starting current and torque

💭 Think About

• Which type of starter is simple and commonly used when motors are small (around 5 HP or less) and the inrush current is usually acceptable? • Which options are more often used when it is necessary to limit starting current for larger motors or weak power systems? • Think about which type of starter requires extra components like resistors, reactors, or special transformers, and whether that is likely for small motors.

✅ Before You Answer

• Identify which choice represents the simplest and least expensive method of starting a small motor. • Eliminate any starters that are primarily used for reducing starting current in larger motors. • Confirm which method connects the motor directly to full line voltage without added series components.
