What is the specific name for the torque produced by a motor at the instant of startup when voltage is applied to the motor?

🔍 Key Concepts

• Starting conditions of an electric motor and what happens before the rotor begins to turn • Difference between torque at standstill vs torque under normal running load • How motor torque terms like locked-rotor, pullout, and breakdown are typically used in electrical/mechanical contexts

💭 Think About

• At the instant voltage is applied and the shaft has not yet begun to rotate, what condition is the rotor in? • Which of these torque terms is associated with the maximum load before stalling, and which is associated with initial, standstill conditions? • Think about which terms describe a limit during operation versus a characteristic only at the moment of starting

✅ Before You Answer

• Match the term that explicitly refers to the rotor being unable to turn at the first instant of energizing • Eliminate any terms that deal with torque when the motor is already running under load and approaching stall • Verify which listed torques are commonly found on a motor nameplate as starting torque or standstill rating
