Zero-Max drives are mechanical adjustable speed drives. Five sizes provide
constant torque of 1.3Nm to 22.5Nm (12“lbs to 200”lbs) throughout the
speed range. The speed range is infinitely adjustable from 0 to 1/4 of
the input speed under full rated load . This is generally stated as
0-320 RPM under full rated load assuming an input of 1440 RPM.
For lower speed/higher torque applications, some Zero-Max Drives are
available with in-line or right angle gearheads. They may be connected
to any rotating power source up to 2000 RPM.
Speed adjustments are easily made by moving a lever control through an
arc or turning the handwheel of a screw type control. In either case,
precise speed control settings are possible.
