The IB series of miniature high performance stepper motor drives are
designed for today’s quality minded, price sensitive market. The 40 volt
series has a +12 to +40 VDC input voltage, up to 3.5 Amps per phase
drive current and a maximum step frequency of 40kHz. The 80V series
has a +24 to +80 VDC input voltage, up to a powerful 9 Amps per phase
of drive current and a maximum step frequency of 250kHz. All of these
drives feature pin compatibility, optically isolated logic inputs, and a 20
kHz chopping rate to reduce noise. In addition, all these drives are single
supply.

The IB462 packs a powerful 160 Watts into less than 3 cu. in. This drive
operates from +12 to +40VDC and effortlessly outputs 2 Amps per phase.
This high voltage allows for greater speeds at higher torque without having to
resort to expensive drives or larger motors.
The high efficiency of the IB462 chopper drive along with its miniature
size make 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.

The IB463 has an output capability of up to 3.5 Amps per phase and,
while it operates at the same voltage range as the IB462, it can deliver 1.4
times more power. This equates to 230 Watts of power in a package that
only requires 3.6 cubic inches of real estate.
The IB463 is ideal for those applications requiring more power, but where
size and cost are still important factors.

The IB104, 106 and 1010 use MOSFET technology to achieve high power
from a miniature package. These drives are designed to get maximum
performance from larger, higher torque motors. This type of performance
is required for today’s most demanding applications.
