Introduction to Motorized Pulleys

Motorized Pulley Range Diameter: 8.50”f to 31.50”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

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

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

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

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

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.

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
