Specifications:

  • 7 sizes from fractional to 10 HP capacity
  • Torque ranges from 0.8 to 110 Nm (up to 14,000 Nm with integral speed reducer).

Features:

  • Overload protection assured
  • Infinite variability from 41% motor speed to zero RPM
  • NEMA and IEC motor mounts
  • Handwheel or motor control
  • Speed, temperature, and torque monitoring optional
  • Integrated gearboxes for high torque applications
  • Remote control capability
  • Optional axial load bearing boxes

Benefits Over Friction Drives:

  • No possibility of slip through
  • Wider speed range to zero RPM
  • No downtime due to overload damage
  • Longer life
  • Explosion proof

Benefits Over Frequency Inverters:

  • Maximum output torque available at zero to full speed
  • Higher power density
  • Less costly explosion proof solution

Control System Options:

  • Variable Speed Adjustment - Standard hand wheel or gauged handwheel for precise repeatable adjustment. Electric remote control is also available.
  • Plarotronic Electronic Speed Control - Provides automated speed monitoring and control. The programmable controller can vary or maintain speed and display parameters.
  • Plarotorque Electronic Torque Meter - Monitors, calculates, and displays actual torque for process control. Provides precise information on efficiency, power demand, temperature, and torque utilization.
