IB462 • IB463
MINIATURE HIGH PERFORMANCE BIPOLAR STEPPING MOTOR DRIVES
THE IB463
With an output capability of up to
3.5 amps per phase, the IB463,
which is only slightly larger than
the IB462, can deliver 1.4 times
more power.
Although the IB463 circuit fits into
an area of less than 10.7 cubic
inches, it is capable of delivering a
powerful 230 watts!
The IB463 is ideal for those
applications requiring more power,
but where size and cost are still
important factors.
DESCRIPTION
Intelligent Motion Systems has
succeeded in developing a line of
miniature high performance
stepper motor drivers for today’s
quality minded, price sensitive
market. Recognizing the wide
variety of needs in a rapidly grow-
ing motion market, IMS has
responded with some of the
smallest, low cost stepper drives
available today.
IMS has included features usually
found only in the larger, more
expensive drives – single supply,
optically isolated inputs, half and
full step, and a chopping rate of
over 20 kHz that eliminates
audible noise.
Their small size make the IB462
and IB463 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 IB462 and IB463 are just two
in our growing line of high perfor-
mance, cost effective drives.
THE IB462
The IB462, our smallest and
lowest priced drive, packs a
powerful 160 watts into less than
8.6 cubic inches.
IB462 will effortlessly output up to
2 Amps per phase.
The IB462 operates from 12 to
40 Volts. This high voltage allows
for greater speeds at higher
torque without resorting to expen-
sive drives or larger motors.
The high efficiency of the IB462
chopper drive, along with its
miniature size, makes it ideally
suited to replace the less efficient
L/R drives. In addition, the low
cost and off-the-shelf availability of
the IB462 permits an immediate,
cost effective solution to an in-
house design.
