Excellence in Motion


The Microstepping MForce PowerDrive
is a high performance, low cost micro-
stepping driver that delivers unsurpassed
smoothness and performance achieved
through IMS’s advanced 2nd generation
current control. By applying innova-
tive techniques to control current fl ow
through the motor, resonance is signifi -
cantly dampened over the entire speed
range and audible noise is reduced.

Microstepping MForce PowerDrives ac-
cept a broad input voltage range from
+12 to +75 VDC, delivering enhanced
performance and speed. Oversized input
capacitors are used to minimize power
line surges, reducing problems that
can occur with long runs and multiple
drive systems. An extended operating
range of –40° to +85°C provides long
life, trouble free service in demanding

The high, per phase output current of up
to 5 Amps RMS, 7 Amps Peak, allows
the extremely compact MForce Power-
Drive to control a broad array of motors
from size 23 to size 42.

The microstepping drive accepts up to 20
resolution settings from full to 256 mic-
rosteps per full step, including: degrees,
metric and arc minutes. These settings
may be changed on-the-fl y or downloaded
and stored in nonvolatile memory with the
use of a simple GUI which is provided.
This eliminates the need for external
