An induction motor has input power of 40 kW. If the stator, core, and mechanical losses are 1000 W, 600 W, and 300 W respectively, calculate the overall efficiency and loss fractions.
💡 Hint: Use the input power to find Pag and then break down losses.
A motor running at 1500 RPM has an input power of 30 kW. If its efficiency is recorded as 85%, calculate the output mechanical power and analyze the energy loss.
💡 Hint: Efficiency is key in determining the performance of the motor.
