The inside-out stepmotor (IOS) construction places the rotor assembly to the outside while the stator remains in the middle. The unconventional design lends itself well to through-hole applications where pipes, wires, and conduits must pass through the centerline of the stepmotor.

The inside-out stepmotor (IOS) construction places the rotor assembly to the outside while the stator remains in the middle. The unconventional design lends itself well to through-hole applications where pipes, wires, and conduits must pass through the centerline of the stepmotor.


A new patented design by Intelligent Motion Systems Inc. is the opposite of conventional hybrid stepmotor orientation. The inside-out stepper, or IOS, places the rotor assembly on the outside of the stator assembly, This orientation makes it possible to hollow out the core of the motor creating a "through hole," Such a feature invites innovative solutions for linear positioning, rotary, and gearbox systems.

The IOS delivers up to 1,200 lb of linear force at speeds <1 rps with repeatable accuracy to ±3 arc-min. In addition, the prime-ratio lamination architecture of the IOS42 augments motor torque and efficiency, reduces low-speed agitation, and significantly enhances smoothness of rotation.

Compared to traditional approaches, IOS motors let designers eliminate components to simplify mechanical designs, shrink footprints, and lower overall cost.
