The new inside out stepper (IOS) motor was designed by IMS to bring
versatility to stepper motors using a unique multi-functional, hollow core
design.
This versatile new motor can be converted to a ball screw linear actua-
tor by mounting a miniature ball screw to the front shaft face. Ball screw
linear actuators offer long life, high efficiency, and can be field retrofit-
ted. 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 damping between the motor
and the load. The induced backlash from the gearbox is
eliminated providing improved bi-directional position accu-
racy.
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:
