Challenge Problems
Push your limits with challenges.
Question 1
An induction motor requires a starting torque of 150 Nm and operates with a maximum breakdown torque of 300 Nm. What slip values correspond to these torques if the synchronous speed is 1500 RPM?
💡 Hint: Use the torque-slip formula involving breakdown torque values.
Question 2
A motor operates at a breakdown torque of 400 Nm and a starting torque of 200 Nm. If the slip at starting is 1 (100%), determine the performance at a slip of 0.2 (20%).
💡 Hint: Consider how the torque varies with different slips and how it might stabilize.
