A new stepmotor design boosts efficiency and reduces noise and vibration.
The inside-out prime-ratio stepper
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.
