Conveying Motorized Driven Roller (DMD Roller)

Product catalog summary

MDR General Information

Product Overview: Motorized Driven Rollers (MDR) are designed for the logistics industry, featuring a diameter of φ50mm and available in steel zinc plating or stainless steel.
Performance Parameters: The rollers operate efficiently within an ambient temperature range of -20 to 45℃ and humidity of 20-90% RH. They offer different speed gears corresponding to varying torques.
Static Load Capacity: The maximum roller length is 1200mm, with load capacities varying by roller length.

MDR Dimension

No Interlocking: Specifications for rollers without interlocking mechanisms.
Transmission Types: Includes O belt-grooved, poly-vee pulley, and double sprocket options.
Taper and Bracket: Details on taper dimensions and bracket usage, with a recommendation against external thread installation.

MDR Product Selection

Drive Force and Torque: Guidelines for selecting the appropriate drive force and starting torque for conveying applications.
Calculation Examples: Provides methods and examples for determining the quantity of interlocking rollers required.

Drive Card

General Function: Overview of the drive card's role in MDR operation.
Rating Parameters: Specifications for matching the drive card with MDR, including dimensions and connection details.

Direct Drive Gearless Feature

Energy Efficiency: Gearless design reduces mechanical energy loss, improving efficiency by at least 10% over traditional MDRs.
Precision Control: Utilizes a 17-bit absolute encoder for high precision servo control.
Temperature Range: Operates effectively in temperatures from -20 to 45℃ without needing different types for high or low temperatures.

Bracket Installation
The document outlines the installation procedure for brackets used with motorized driven rollers (MDR). It emphasizes the importance of using mounting brackets to secure the motor shaft to prevent severe shaking and abnormal noise. The installation involves tightening M5 bolts and nuts first, followed by hex socket screws with specified torque values. The document specifies that conical motorized rollers should only be installed vertically.

Specifications and Dimensions
The document provides detailed dimensions for various components, including M5 nuts, bolts, and hex socket screws. It lists dimensions for different roller diameters and lengths, emphasizing the importance of selecting the correct size for specific applications.

Drive Force and Torque Calculations
Formulas for calculating drive force and starting torque for conveying are provided. The document explains the factors affecting these calculations, such as friction coefficient, weight of goods, and roller diameter. It also discusses the loss factor for interlocking rollers and provides a product selection example based on these calculations.

Drive Card Functions
The drive card supports multiple speed stages, dynamic braking, and RS485 communication. It includes settings for speed, acceleration, and deceleration, with a DIP switch for configuration. Proper grounding is emphasized to prevent static damage.

Installation and Product Selection
The document provides guidelines for installing MDRs in conveyor zones and selecting the appropriate motor type based on torque requirements. It highlights the impact of conveyed surface and roller bed flatness on conveying capacity and suggests a safety factor range of 1.5-3.

General Information
The document concludes with general information about the company's focus on motorized driven rollers and related technologies for the logistics industry, along with contact details.
