The new inside out stepper (IOS) motor was designed by IMS to bring versatil-
ity to stepper motors using a unique multi-functional, hollow core design.
This versatile new motor can be converted to a ball screw linear actuator by
mounting a miniature ball screw to the front shaft face. Ball screw linear actua-
tors offer long life, high efficiency, and can be field retrofitted. There is no need
to throw the motor away due to wear of the nut or screw.
The IOS motors offer the following features:
n
The shaft face diameter offers a wide choice of threaded
hole patterns for coupling.
n
The IOS motor can be direct coupled in applications within
the torque range of the motor, eliminating couplings and
increasing system efficiency.
n
The IOS motor can replace gearboxes in applications where
gearboxes are used for inertia dampening between the mo-
tor and the load. The induced backlash from the gearbox
is eliminated providing improved bi-directional position ac-
curacy.
n
Electrical or pnuematic lines can be directed through the
center of the motor enabling the 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.
n
Light beams can be directed through the motor for refraction
by a mirror or filter wheel mounted on the shaft mounting
face.
n
The IOS motor 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.
n
The motor is compatible with IMS bipolar drivers, keeping
the system cost low.
n
The IOS motor can operate up to 3000 rpm’s.
The IOS motor is available in the following frames:
