A Stall Torque Motor Operated Cable Reeling Drum is a specialized motorized drum system used to automatically wind and unwind cables in various industrial applications. This type of drum is driven by a stall torque motor, which provides a constant torque even at zero or very low speeds. The design ensures consistent cable tension and controlled winding without complex controls or feedback systems.

These types of cable reeling drums are normally used for cables of size 4C X 25 sq mm (max) and cable lengths up to 20 Mtrs. However, these drums can be used even up to 150 Mtrs if the cable diameter is small (say 4C X 2.5 sq. mm )

In case of stall torque motorized cable reeling drum, the stall torque motor remains energized in both winding and unwinding operation of cable. In case you want to save power during long stoppages of machine, then a contactor and timer circuit can be installed in your panel. However, this is only an optional feature and is not a mandatory requirement. Since the stall torque motors are continuously on during both winding and unwinding direction.

Advantages of Stall Torque Motor Operated Cable Reeling Drum :

Constant Torque Output provides consistent torque irrespective of cable length or winding position, ensuring smooth and uniform cable retraction. Simplified Control System eliminates the need for complex control electronics since the stall torque motor inherently limits torque, making it more reliable and easier to maintain.

Safe Cable Handling reduces the risk of cable damage due to over-tensioning, as the motor stalls at a preset torque limit, protecting both the cable and connected equipment. Operates efficiently during stall conditions without excessive power consumption, especially suitable for intermittent or infrequent operation.

Smooth Operation ensures jerk-free winding/unwinding of cables, enhancing the lifespan of both the cable and drum mechanism. Compact and Robust Design is suitable for harsh industrial environments with a design that requires minimal space and can withstand tough conditions.

It is ideal for Variable Cable loads and performs reliably with varying cable lengths or changing tension requirements, making it adaptable for different applications. Fewer mechanical components and simpler design reduce wear and tear, leading to lower maintenance needs and costs.

Long service life and low operational complexity make it a cost-efficient choice for continuous cable reeling operations.

Stall Torque Motor Operated Cable Reeling Drum application industries :

Stall Torque Motor Operated Cable Reeling Drums are widely used in industries where cables must be automatically wound and unwound under constant tension, especially in moving machinery. These drums provide reliable performance in demanding conditions due to their ability to maintain torque even when stalled (not rotating).
