Motorized Roller Conveyor (MDR)

Introduction

Motorized Roller Conveyors—also known as Motorized Drive Roller (MDR) conveyors—feature built-in motors within selected rollers, enabling controlled, energy-efficient, and modular material handling. Unlike traditional roller conveyors, MDR systems offer zone-level control, smooth accumulation, quiet operation, and simplified wiring—ideal for modern warehouses, distribution centers, and assembly lines.

Specifications

• Drive Technology: 24 V DC brushless MDR with chain/belt drive to adjacent rollers
• Roller Diameters: 50 mm–100 mm and specialty sizes (e.g. 60, 80 mm)
• Roller Centers: 75 mm–120 mm pitch, custom center spacing
• Load Capacity: ~35 kg per roller; complete system handles pallets and totes up to 1,800 kg
• Speed Range: 5–90 m/min, adjustable via VFD or drive cards
• Power & Voltage: 24 V DC roller drive; AC 230–415 V, 50/60 Hz supply to controllers
• Frame Materials: Powder-coated steel, CRC sheet C-channel; SS frame optional
• Environmental Rating: IP54-IP65; suitable for –10 °C to +40 °C ambient; washdown options available

Ideal Industries & Applications

• E-commerce & Distribution: Modular accumulation with package sorting capabilities
• Warehousing: Carton, tote, and pallet transport with zone control
• Manufacturing & Assembly: Part transport, staging, and transfer lines
• Food & Pharma: Clean-room compatible, washdown-ready stainless finishes
• Airport & Parcel Handling: Quiet, safe belt-free accumulation systems

Key Features & Benefits

• Zone-Level Control & ZPA: Motorized rollers support zero-pressure accumulation for smoother staging
• Energy-Efficient & Low Noise: Run-on-demand avoids idle energy use; MDRs are significantly quieter
• Plug-and-Play Installation: Built-in rollers require no external motors or gearboxes
• Customizable Zones: Easily add/remove sections as needed, drive and control via PLC/VFD
• Scalable & Flexible Layouts: Supports straight, curved, incline, and merge/divert configurations
• Integrated Safety: Jam/overload detection, emergency stop functionality, and compliant mechanical design

Parab Conveyor Systems' MDR Solutions
