  1. Motorized Pulley Presentation

  2. Introduction to Motorized Pulleys

  3. Motorized Pulley Range • Diameter: 8.50”f to31.50”f • Power: fractional HP to 180 HP • Belt Speed: 24 to 1,000 fpm • Voltage: 115v/230v/380v/460v/575v • Phase: single and three phase • Frequency: 50 & 60 Hz; VFD compatible

  4. Stationary external shaft Permanently oil Filledfor cooling and lubrication Gear box Rotating drum Electric AC Motor Terminal box Motorized Pulley Concept Motorized pulley an alternative to the exposed drive

  5. Motorized Pulley Cross Section Tube “Drip Lip” Stator Rotor Gearbox Oil Terminal Box

  6. Compact! • Hermetically Sealed • Aesthetic design • Space saving compact design • Light weight • Safer than conventional drives

  7. Hermetically Sealed – IP67 RULMECA Motorized Pulleys - the perfect drive unit for corrosive chemicals and abrasive bulk materials: • Copper & steel • Coal • Limestone • Potash • etc.

  8. Easy to Maintain RULMECA Motorized Pulleys – Low Maintenance Requirements (change oil every 10,000 operating hours): • Remove magnetic oil plugs • Wipe off sludge • Drain oil • Refill

  9. High Efficiency The pulley is driven directly by the internal gearbox, giving the Motorized Pulley an efficiency of: 95% Therefore, less energy is required. This makes Rulmeca Motorized Pulleys to one of the most economical conveyor drives.

  10. Extra Thermal Protection All RULMECA Motorized Pulleys have 3 built-in thermal protection switches: • Connect to normally closed control circuit • Designed to provide back up to plant current overload protection

  11. Rubber and ceramic lagging options Full rubber diamond Partial rubber diamond Partial rubber smooth Full ceramic diamond

  12. “Holdback” Options • Mechanical Backstops • Internal Brakes • External Brake Shafts

  13. “Holdback” Options Mechanical Backstop • Fastens to Motor Rotor • Mechanical Advantage (up to 100:1 gear ratio) • Protected Environment (hermetically sealed)

  14. “Holdback” Options Internal Brake • Fastens to Motor Rotor • Mechanical Advantage (up to 100:1 gear ratio) • Protected Environment (hermetically sealed)

  15. “Holdback” Options External Brake Shaft Hydraulic shoe brake (by others) installed on 800H Motorized Pulley External brake shaft extends rotor shaft through pulley main shaft
