Indexing.
Used to divide the circle of rotation into equal divisions. Say you wanted to make a fluted column with 24 flutes. You would use an indexing plate with 24 holes in its periphery to hold the column while you routed each flute.

Induction motor.
A type of A.C. electric motor which does not have "brushes". Most lathe motors are induction. The speed of the motor is proportional to the frequency of the A.C. supply so electronic speed controllers are complicated and expensive.
