Motorized Pulley Presentation Slide 2 Motorized Pulley Training Agenda Introduction to Motorized Pulleys Introduction to Rulmeca Motorized Pulley Applications Aftermarket Service Website Visit Conveyor Design Software Slide 3 Introduction to Motorized Pulleys Slide 4 Diameter: 8.50 to 31.50 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 Motorized Pulley Range Slide 5 Stationary external shaft Permanently oil Filled for cooling and lubrication Gear box Terminal box Electric AC Motor Rotating drum Motorized Pulley Concept Motorized pulley an alternative to the exposed drive Slide 6 Stator Rotor Tube OilGearbox Terminal Box Drip Lip Motorized Pulley Cross Section Slide 7 o Hermetically Sealed o Aesthetic design o Space saving compact design o Light weight o Safer than conventional drives Compact! Slide 8 RULMECA Motorized Pulleys - the perfect drive unit for corrosive chemicals and abrasive bulk materials: n Copper & steel n Coal n Limestone n Potash n etc. Hermetically Sealed IP67 Slide 9 Easy to Maintain RULMECA Motorized Pulleys Low Maintenance Requirements (change oil every 10,000 operating hours): n Remove magnetic oil plugs n Wipe off sludge n Drain oil n Refill Slide 10 The pulley is driven directly by the internal gearbox, giving the Motorized Pulley an efficiency of: Therefore, less energy is required. This makes Rulmeca Motorized Pulleys to one of the most economical conveyor drives. 95% High Efficiency Slide 11 Extra Thermal Protection All RULMECA Motorized Pulleys have 3 built-in thermal protection switches: n Connect to normally closed control circuit n Designed to provide back up to plant current overload protection Slide 12 Rubber and ceramic lagging options Full rubber diamond Partial rubber smooth Partial rubber diamond Full ceramic diamond Slide 13 Holdback Options n Mechanical Backstops n Internal Brakes n External Brake Shafts Slide 14 Holdback Options Mechanical Backstop Fastens to Motor Rotor Mechanical Advantage (up to 100:1 gear ratio) Protected Environment (hermetically sealed) Slide 15 Holdback Options Internal Brake Fastens to Motor Rotor Mechanical Advantage (up to 100:1 gear ratio) Protected Environment (hermetically sealed) Slide 16 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
