Black Max® Vector Duty
1000:1 Constant Torque Motors
Black Max® TENV motors are used in any high performance application, utilizing
Closed- or Open-Loop Vector controls or Volts/Hertz drives, for countless machinery
applications, where full torque at zero speed is required. The low inertia design
provides extremely quick response to accel and decel commands, as well as changes
in direction. Uses include machine tool, conveyors, palletizers, crane & hoist systems,
accumulators, packaging equipment, extruders, converting equipment and numerous
other motion control applications.
