Size 17 frame inside-out stepper motor

The innovative 17 frame IOS motor from Intelligent Motion Systems Incorporated, Marlborough, CT, is designed to give versatility to small robotic style motors using a multi-functional, inside-out hollow-core design, allowing users to reduce inventory and save cost. This motor can be converted to a ball screw actuator by mounting a miniature ball screw to the front shaft face. (Ball screw linear actuators offer long-life, high-efficiency, and can be field retrofitted, so there is no need to throw the motor away due to wear of the nut or screw.) The shaft face diameter offers a wide choice of threaded hole patterns for coupling. The IOS motor can be direct coupled in applications within the torque range of the motor eliminating couplings and increasing system efficiency.

The hollow shaft allows electrical or pneumatic lines to be directed through the center of the motor, enabling motors to be stacked end-to-end or applied in robotic end effector applications. The through-hole is stationary, preventing cables from being chaffed by a moving hollow shaft. In addition, light beams can be directed through the motor for refraction by a mirror or filter wheel mounted on the shaft mounting face. The IOS is adaptable to valves, enabling the valve stem to protrude above the motor frame. The stem can be retrofitted with a dial indicator showing valve position.

The IOS motor can replace gearboxes in applications where they are used for inertia dampening between the motor and load. The induced backlash from the gearbox is eliminated providing improved bi-directional position accuracy. The IOS motor can operate up to 3000 rpms and is compatible with off-the-shelf bipolar chopper microstepping drivers keeping the system cost low.
