repeatable pulse train source with features designed for the needs of computer controlled
process lines. It may be used for master speed setting or as an extremely accurate ratio
setting device.
to this speed setting device is not necessary to maintain the speed regulation of the
system. The nature of the permanent magnet based Brushless motor and control system
is that it will maintain zero percent speed regulation from no load to full load over its entire
speed range. Closing the speed loop for speed regulation is unnecessary. Speeds

operating conditions. The Brushless motor will run at exactly the speed at which it is told
to run, and the next time that same speed is commanded, it will be repeated exactly.
and it can switch between the two on the fly. This consistent speed control is invaluable
in setting up processes which vary from day to day, but must be duplicated from order
to order.
it is easily accessible to operators, which may be remote from the location of the motor
control. Control inputs and outputs are isolated, for flexibility and immunity to interactions
between units.
