Bulk Handling

The Rulmeca Motorized Pulley is a highly efficient geared motor drive, which is hermetically sealed in a steel cylindrical shell. The shell, which is normally crowned to ensure belt tracking, is fitted with bearing housings incorporating precision bearings, double lipped oils seals and rotates on a pair of shafts. The motor stator is fixed to the shafts and the motor winding cables passes through one of the shafts, eliminating the need for slip rings and brushes. General description The squirrel cage induction motor, manufactured in steel laminate, is machined concentric to high tolerances and designed to give 200 % starting torque for 3 phase versions. The rotor pinion is coupled directly to the gearbox. The gearbox transmits torque to the shell through a geared rim and provides a highly efficient motor, with very little frictional losses. The Motorized Pulley is oil filled, which acts as a lubricant and coolant. Heat is dissipated through the shell and conveyor belt. All vital parts are CNC machined!
