The IM483H/IM805H is a high performance, yet low cost microstepping driver
that utilizes advanced hybrid technology to greatly reduce size without sacrific-
ing features. The IM483H/IM805H is exceptionally small, easy to interface and
use, yet powerful enough to handle the most demanding applications.
The IM483H/IM805H has 14 built-in microstep resolutions (both binary and
decimal). The resolution can be changed at any time without the need to reset
the driver. This feature allows the user to rapidly move long distances, yet
precisely position the motor at the end of travel without the expense of high
performance controllers.
With the development of proprietary and patented circuits, ripple current has
been minimized to reduce motor heating common with other designs, allow-
ing the use of low inductance motors to improve high speed performance and
system efficiency.
The IM483H/IM805H, because of its ultra small size and low cost, can be used
to increase accuracy and smoothness in systems using higher step angle motors.
In many instances mechanical gearing can be replaced with microstepping,
reducing cost and eliminating potential maintenance.
Available as options for the IM483H/IM805H are the HFC-22 Heat Sink/Fan/Clip as-
sembly and the PR-22 Pin Receptacle carrier. The HFC-22 provides a unique cooling
solution and was designed specifically for the IM483H and IM805H Hybrid Micro-
stepping Drivers. The HFC-22 will easily maintain a reliable rear plate temperature
without using large heat sinks and cumbersome mounting hardware. The heat sink
and fan are easily mounted to the driver by means of a removeable clip developed by
IMS. The HFC-22 fully assembled with the IM483H or IM805H takes up only 6.8 in
of space! For applications where ease of removal is required, the PR-22 provides reli-
able, high quality receptacle set which comes attached to a high temperature plastic
throwaway carrier that allows for ease of placement for wave or hand soldering.
The IM483H/IM805H was developed to provide designers with affordable, state-of-
the-art technology for the competitive edge needed in today's market.
