The counting may be done electronically, usually in clocks with digital displays, or, in analog clocks, the AC may drive a synchronous motor which rotates an exact fraction of a revolution for every cycle of the line voltage, and drives the gear train.
Most linear motors in use are LIM (linear induction motor), or LSM (linear synchronous motor).
The low-acceleration, high speed and high power motors are usually of the linear synchronous motor (LSM) design, with an active winding on one side of the air-gap and an array of alternate-pole magnets on the other side.
The reactive power drawn by the synchronous motor is a function of its field excitation.
