A 150 m long train crosses an electric pole in 10 seconds Calculate the speed of the train?
The train travels 150m in 10seconds, Therefore it travels 900m in 1 minute and thus 54000 metres in 1 hour. The train's speed is therefore 54 kph (kilometres per hour)
What is pole pitch?
Suppose we have a N-pole electrical machine, then the angular distance between the consecutive poles when expressed in degrees is POLE PITCH. eg. for a two pole machine (one north and one south pole), the pole pitch is 180 degrees, and for a 4-pole machine: it is 90 degrees. Note that this is so when expressed in Mechanical degrees, whereas in Electrical degrees it is always 180 degrees. Therefore: POLE PITCH (mechanical)=180/(n/2): n=no pf poles.
What are the two sides of magnet called?
