Synchronous motor - Wikipedia

A synchronous electric motor is an AC motor in which, at steady state, the rotation of the shaft is synchronized with the frequency of the supply current; the rotation period is exactly equal to an integral number of AC cycles. Synchronous motors contain multiphase AC electromagnets on the stator of the motor that create a magnetic field which rotates in time with the oscillations of the line ...

Induction vs Synchronous Machines • Engineering Scribbles

Synchronous Machines (Motor) Operation Principle. We already know that in the stator there is a rotating magnetic field. So, in the case of synchronous motors, instead of generating a Lorentz Force, we lock the poles of the stator's DC electro-magnet with the rotating 3-phase's field. This means for example the North pole of the ...

The Capstan Motor is of the Hysteresis-Synchronous type, incorporating a special design feature to prevent hunting. By switching to either the 6 or 12 pole stator winding, the tape speed of 7 1/2 or 3 3/4 ips may be selected. The capstan drive, the pinch roller assembly and the headblock with the tape guides are carried on one die-cast frame.

Belts and Pulleys - Motion Control Tips

Minimum wrap angle is a measure of how much the belt wraps around the smallest pulley. Belt length is how long the belt would be if cut and laid flat. Finally, in the case of toothed belts (also called synchronous belts) the pitch is the number of teeth per some length—so a 3-mm pitch means that the belt has one tooth every 3 mm, for example.
