MINIATURE HIGH PERFORMANCE BIPOLAR STEPPING MOTOR DRIVERS
DESCRIPTION
Intelligent Motion Systems contin-
ues to meet the needs of a grow-
ing motion industry with these
powerful, high performance
stepper motor drivers — the
IB104, IB106 and IB1010.
Using MOSFET technology to
achieve high power from a minia-
ture package, these drives have
what it takes to get the maximum
performance from the larger,
higher torque motors. This type of
performance is required for
today’s most demanding applica-
tions. OEM designers will appreci-
ate not only the enhanced capabili-
ties in such a small package, but
the LOW price as well.
These 80 volt drives have ad-
vanced features usually found only
in more expensive drives — single
supply, optically isolated inputs,
half and full step, and a chopping
rate of over 20 kHz that elimi-
nates audible noise.
IMS has preserved pin compat-
ibility with our smaller drives for
an easy upgrade if more power is
needed. In addition, their small
size makes them ideal for PC
board mounting, but they can
also be frame or chassis
mounted and will accept 0.200/
0.196 center connectors or plug
type terminal strips.
THE IB104
The IB104 operates from +24 to
+80 volts at 4 amps/phase for
lower power applications requir-
ing high voltage performance.
The IB104 will run cooler be-
cause it uses the same MOSFET
technology as our larger 80 volt
drives.
THE IB106
Higher performance motors
require more current. The IB106
was designed for applications
requiring increased power.
THE IB1010
The IB1010 has the same high
input voltage (+80V), yet with even
MORE power! A full 9 Amps per
phase for an incredible 1800
watts!
The IB1010 uses the same small
package as the IB106, but with
an output power increase of 50%!
The IB1010 is for those applica-
tions requiring maximum power,
but where size and cost are still
important factors.
