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 plus or minus 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.
