The Van der Graaf Drum Motor is a one component conveyor drive which houses all components internally, eliminating the need for external components like motor, gearbox, sprockets, chain, chain guard and pillow block bearings. This reduces operating and maintenance costs, improves safety conditions, and because it is completely sealed our drum motors can operate in extreme environmental conditions. The rugged design of the Van der Graaf drum motor provides the end user with a quieter environment, space savings, efficiency and reliability with virtually no maintenance. The drum motor offers a...

STANDARD FEATURES CAST IRON COMPONENTS Every Van der Graaf Drum Motor utilizes cast-iron gear housing and motor flanges. By choosing cast-iron over lighter cast-aluminum components, the Van der Graaf Drum Motor is able to withstand greater levels of belt tension over typical motorized pulley designs. HUB DESIGN: Design A: Bearing hubs exend beyond the shell CONSTRUCTION MATERIAL Drum motors are available in all mild steel and optional all stainless steel construction (see Drum Motors Options). COOLING The drum motor is designed with all vital components, such as motor and gear reducer...

OPTIONS ALL STAINLESS STEEL All units are available in all stainless steel construction, including end caps, shell, shafts and junction box. NON-STANDARD LENGTH / EXTRA LONG FACE WIDTH Please contact your Van der Graaf technical representative for details. GV THERMAL (GVTHERM) OVERLOAD PROTECTION Thermal overload protectors are devices, embedded into the motor windings (one per phase) and are available for both Class F and H insulation. These are bi-metal type devices, maintaining continuity under normal temperature conditions. When temperature within the motor rises above 135˚C for Class F...

OPTIONS ELECTROMAGNETIC BRAKE (RTM) The drum motor with an all-internal electromagnetic brake provides accurate and positive stopping engagement. The motor and all rotating components come to a complete stop when power is disengaged. When power is engaged, the brake releases, allowing the motor to operate as designed. The RTM drum motor is bi-directional and ideal for cycles up to 40 starts and stops per minute. Typical applications include baggage handling, manufacturing and assembly lines, palletizing and package operations, among others. CLUTCH BRAKE (CBTM) The patented Clutch Brake Drum...
