Plaromaster Elastohydrodynamic Variable Speed Drives

Planetroll’s patented design offers several significant advantages over traditional friction drives and frequency inverters in applications requiring high torque at startup, explosion proof operation, infinite variable speed to zero RPM, and reliable overload protection.

  • 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
  • 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)

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
