Where a standard stepping motor needs a gearbox to present the proper inertia to a load, the same size or smaller IOS motor can drive the load without a gearbox, reducing footprint and cost. IOS motors are available in 17,23,24,42 frame sizes.
Designed for linear actuator, linear slide, and rotary table applications, this patented IOS stepping motor eliminates gearbox, couplings, belts, and pulleys. Its non-rotating through hole accommodates signal wires, communication cables, linear actuator shafts, or vacuum lines.
To use as a linear actuator, attach a ball screw to the motor's rotating mounting face. When compared to traditional linear slide applications with a rotating ball screw, a fixed-screw IOS system will move a carriage faster and over longer distances. For rotary tables, the IOS eliminates induced backlash from the gearbox for higher speed and improved non-cumulative positional accuracy within ±3 arc-minutes.
Unlike conventional stepper motors, the IOS magnet surrounds the rotor cups. This simple difference permits higher load-carrying bearings. The motor can also be tightly preloaded because of the larger Belleville washers used for preloading.
