A 200 V d.c. shunt motor takes 4 A at no-load when running at 700 rpm. The field resistance is 100 Ω. The armature resistance at standstill gives a drop of 6 V across armature terminals when 10 A were passed through it. Calculate (i) the speed full-load, (ii) the armature torque, (iii) efficiency. The normal input of motor is 8 kW

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.
