The torque–speed curve of a particular 10-pole induction motor is approximately linear for low values of slip either side of its synchronous speed. When used as a motor on a 50 Hz supply, its efficiency is 90% and it produces a mechanical output power of 25 kW at a speed of 550 rev/min. Estimate the power produced when the machine is connected to the same 50 Hz mains and driven by a wind turbine at 650 rev/min.
