🔍 Key Concepts
• Rated conditions of an induction motor (horsepower, speed, frequency, voltage)
• Difference between starting torque, pull-out (breakdown) torque, and full-load torque
• How torque relates to the motor’s normal continuous operating point
💭 Think About
• Which choice describes the torque when the motor is running at its normal, nameplate operating point rather than at start or at extreme overload?
• Look for key words like rated horsepower, rated speed, and rated frequency—which option lines up with a motor’s usual running condition?
• Which options clearly refer to special conditions (startup, acceleration, or heavy overload) instead of normal full-load operation?
✅ Before You Answer
• Be sure the definition you pick matches normal continuous operation at the nameplate rating of the motor, not a temporary or extreme condition.
• Eliminate any choice that refers to starting or instant of voltage application, since that is related to starting torque, not full-load torque.
• Check that the correct choice links torque to rated horsepower, speed, and frequency rather than minimum or maximum torque values.
