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.

Motor Load, Torque, and Power Quality Requirement

An electric motor is a gadget that changes electrical energy into mechanical energy over to follow up on a mechanical burden. The weight set on the motor because of this mechanical movement is known as motor load. Appropriately matching the motor burden to the engine is vital to forestall harm to the engine or wasteful and unnecessary expensive activity. Engines perform such undertakings as moving a thing starting with one spot then onto the next, cutting it, changing its shape, etc. The motors might be evaluated as far as a few variables including power yield, voltage, current, and temperature. Harm to an engine might happen when it is worked under over the top engine load contrasted with its appraised limit.
