Specifications
The document outlines specifications for various components and materials used in drum motors and related accessories, including FDA and EC1935/2004 approvals for food safety, Shore hardness ratings for materials, and dimensions for lagging and coating applications.

Procedures and Recommendations
Details are provided for cable connections and configurations for both 3-phase and 1-phase asynchronous motors, emphasizing the importance of using shielded cables to reduce EMC emissions. Recommendations include using anti-vibration brackets to reduce noise and vibration, and selecting appropriate cable connectors and protections for specific applications, especially in the food processing sector.

Options and Accessories
The document lists various options and accessories available for the DL series, including anti-vibration brackets, light duty flanged brackets for drum motors and idler pulleys, and idler pulleys with integrated bearings. It also describes the modular design of the DM 0080 drum motor, which allows for customization to meet specific application requirements.

Technical Data
Technical data for the DM 0080 drum motor includes details on motor types, insulation classes, voltage and frequency specifications, and ambient temperature ranges. The document also provides mechanical data for synchronous motors with steel gear, including rated power, torque, and speed ratios.

Design Variants
Various design variants are available for components such as shells, end housings, gear boxes, and electrical connectors, with options in materials like aluminum, mild steel, stainless steel, and technopolymer.

Applications
The DL 0113 model is highlighted for its lightweight and low-noise design, suitable for small to medium belt conveyor applications. It is adaptable for use in dry logistics and food production environments.

Standards and Certifications
The motors comply with IEC standards and are available with cULus safety certificates. Options for static balancing and various accessories are also mentioned.

Drive Options for Conveyors
Head Drive is preferred for non-reversible conveyors due to simplicity and effective torque transfer. Tail Drive is not ideal as it increases tension on the return side, leading to potential belt issues. Center Drive is suitable for long or reversible conveyors, distributing tension evenly and minimizing tracking issues.

Positive Drive Belt Conveyors
Types include modular plastic belts, steel slatted belts, and chain conveyors. Advantages include lower power consumption and less stress on drum motor bearings. Torque transmission is achieved through rubber lagging or sprockets, with floating sprockets to accommodate thermal expansion.

Design Considerations
Belt Tension generally requires no tension, relying on gravity. Velocity Factor affects motor speed; calculated using a specific formula. Drive Positions: Head or center drives are recommended for positive drive belts.

Special Conveyor Types
Inclined Conveyors require more power and tension; backstops prevent rollback. Knife-edge Conveyors reduce transfer gaps but increase friction. Food Processing Conveyors should follow hygienic design rules for easy cleaning.

Control Systems
Options include brakes, backstops, encoders, and frequency inverters. Speed Setting is influenced by load and belt tension; frequency inverters can enhance precision.

Mounting and Adjustment
Horizontal mounting is standard; special designs needed for non-horizontal setups. Belt Adjustment ensures central tracking and prevents misalignment.

Belt Pull Calculation
Considers various forces and includes a safety factor. Additional friction from hoppers, seals, and cleaning devices is not included in basic calculations.

Application Notes and Design Guidelines
Conveyor Forces and Friction Coefficients: The document outlines the forces involved in operating a double slider bed conveyor, including force without load (F0), force to convey goods horizontally (F1), on an incline (F2), and during accumulation (F3). It provides formulas for calculating these forces using parameters like belt weight, product weight, and friction coefficients. The coefficients of friction for various materials are detailed, affecting the conveyor's efficiency.

Belt Tension and Elongation
Guidelines for calculating belt tension and elongation are provided, emphasizing the importance of matching belt tension with drum motor specifications to avoid damage. The document explains how to measure and calculate belt elongation using a simple method involving marking and measuring the belt.

Drum Motor Selection
Recommendations for selecting the appropriate drum motor diameter are given, considering factors like belt type and application parameters. The document warns against using a drum motor diameter that is too small, which can lead to belt slip.

Single Phase Asynchronous Motors
Details on the use of single-phase AC motors are provided, including their principle of operation, starting torque, and noise considerations. The document suggests using 3-phase motors for better efficiency and provides information on capacitors and relays required for single-phase motors.

Material Specifications
The document specifies materials used in drum motors, such as NBR and PU, highlighting their properties and suitability for different applications. It discusses hot and cold vulcanization processes for rubber lagging to increase friction and reduce belt slip.

Certifications and Compliance
Interroll drum motors are certified according to UL and cUL standards and are EHEDG-compliant for the food processing industry. The document lists compatible cleaning products for maintaining hygiene standards.

Legal Notices
The document includes legal disclaimers about the accuracy of the information and intellectual property rights, emphasizing that the content is for informational purposes only.
