Question

write short note on the following. (1) stepper motor (2) constant voltage transformer​

Answer 1

Answer:

1- A Stepper Motor or a step motor is a brushless, synchronous motor which divides a full rotation into a number of steps. Unlike a brushless DC motor which rotates continuously when a fixed DC voltage is applied to it, a step motor rotates in discrete step angles.

2-

Constant Voltage Transformers don't care about the ambient. Unlike some sensitive electronic stabilisers a CVT works in a very large range of conditions. Standard units can work at permanent temperatures of 40 deg C with 50 deg C not a problem for short periods, alternately a special design can cope with 70 deg C.
