Abstract
An electric stepper motor having increased motor torque includes a thru-hole, a rotor and a stator. The thru-hole allows use with a chamber and provides transport of hardware and elements into the chamber. A first and second pair of rotor cups separated by a non-magnetic spacer disc provide increased motor torque.
