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.

Multi-functional electric stepper motor assembly having increased motor torque

An electric stepper motor includes a thru-hole, a rotor and a stator. The rotor consists of a pair of hollow magnetic metal flange-shaped laminations arranged within a hollow magnetic sleeve. The motor can be field-converted from rotary to lineal translation by attachment of a threaded nut to the motor shaft mounting face. The thru-hole allows use with a chamber and provides transport of hardware and elements into the chamber.
