As it turns out, "going small" is an effort that traces back to the first steppers ever manufactured. Released in 1952, the Sigma "Cyclonome 9" series, one of the first steppers ever designed, was the first standard offering of its kind. Motors had a frame size of 1 3/16 inches, roughly the size of a modern day NEMA 11 motor. With a torque range of 1 - 12 oz-in, common applications at the time included printers, tape readers, and chart drive and display controls. Just like today, the small form factor of these motors allowed OEMs to reduce the overall size and footprint of their machines.
