1.
Start By Determining The Torque Required To Start And Run Your
Machine.
This may be the most important step in selecting the best drive
model for your application. All Zero-Max Drives are rated for
constant torque and variable horsepower throughout the speed
range.
Be sure
to apply the proper Service Factor and consider the Type
of Application.
2. Determine
Speed Range Required For Your Machine Processes.
The Zero-Max Drive speed range of 0-400 RPM is given assuming
an input speed of 1800 RPM and full load on the output shaft.
The selection
of input speed and direction of input have a bearing on final
output speed. Lower input speeds reduce the speed range proportionately.
Running
the input in the non-preferred direction substantially increases
the speed range but may result in shorter life. For best results,
run the Zero-Max in the preferred direction and match its speed
range to your machine requirement.
Take as
much reduction as possible, from the output shaft to the load,
to provide adequate torque and to maximize accuracy of speed
control.
