... In practice this is impossible. Motor has to supply mechanical losses and iron losses alongwith small copper losses. Let us see how it can be explained in case of synchronous motor. 1.2 Synchronous Motor on No Load (With Losses) We have seen that Ebph and Vph are magnitudewise same, which is adjust ...

... A magnetic field B between the pole faces of an electromagnet is nearly uniform at any instant over a circular area of radius r0. The current in the windings of the electromagnet is increasing in time so that B changes in time at a constant rate dB/dt B at each point. Beyond the circular region (r > ...

Sensorless control of induction motor drives equipped with inverter
... inverter consists of sharp-edged voltage pulses, which cause unwanted effects in the motor drive. Sudden alterations of the voltage produce high voltage stresses in motor insulations and may cause bearing currents [1], [2]. Harmonics at the switching frequency and its multiples give rise to addition ...

... When a single wire is bent into a loop and rotated through a permanent magnetic field, we have the basis for a generator. If the loop or armature is turned by some mechanical means (hand crank, pedals, crankshaft of an engine, or a turbine using steam, wind or water) we can generate electric power. ...
