In one sense, they are quite similar. If you are asking about
the Superior Electric steppers vs. their "Slo-Syn" motors,
the only difference is that the Slo-Syn motors usually are wound
for 120 V AC drive, and have very high inductance compared
to similar stepper motors. This limits their top speed.

In a more general sense, the biggest difference is that stepper
motors are optimized for moving in small increments and having
high holding torque, while synchronous motors are optimized
for moving at constant speed, as for clocks and tape recorders.
Otherwise, the stepper motor usually has a lot of poles, and
the synchronous motor usually has from 2 to 8 poles. But, there
are synchronous motors with a high pole count.
