Turntables are responsible for turning vinyl records at specific speeds. Most have a motor and belt drive system to make this work. Some use variable speed motors make the records spin at the standard 3 speeds of 78, 33 1/3, and 45 revolutions per minute. Others use a single speed motor that employ gears to make the necessary rpm’s. A needle is placed on top of the vinyl as it spins to read the grooves on the record and translates this into the sound you hear.
