TORQUE COMPARISON
As a simple 2 Amp driver, the R208 outperforms all
of its competitors in its class in maximizing the torque
output of a step motor. In the test below you can see
that it even outperforms the IMS IM483, a driver that
costs over twice as much. Using a standard 1.8° step
motor at 8x microstepping, you can see how the R208
outperforms the competition on the torque/speed
curve below. The R208 gets over 10% more torque out
of the motor at the various speeds compared to the
lowest performer.
TEMPERATURE COMPARISON
The R208 directly competes with the IMS IB462. They
are both 2 Amp peak drivers. Both feature full and
half step, while the R208 is also capable of 4x and 8x
microstepping. Using a standard 1.8° Step motor, 24
VDC, 2 Amps/phase, half-stepping, and 20 revolutions
per second, you can see that the R208 runs much
cooler than the IB462. After running both for 120
minutes the R208 is at 129° F (53.8° C), while
the IB462 is at 138° F (58.8° C). If overall system
temperature is important in your application, the R208
has a clear advantage running 9° F (5° C) cooler.
