High-Torque 216mm Drum Motor - Heavy-Duty Motorized Pulley for Bulk Material Handling | China Suppliers Factory
Product Overview
The DM216 series is purpose-built for industries that transport heavy single-unit items or massive volumes of bulk material. Its extremely rugged construction allows it to withstand significant radial loads and constant high-load cycles. This makes it an essential component for heavy-duty warehouse loading, agricultural transport, and industrial-scale conveyor lines.
Precision Transmission with Low-Noise Operation
Quiet efficiency is a hallmark of the DM series. The DM216 features a gearbox made of high-alloy steel gears that undergo precision grinding. This meticulous manufacturing process ensures that despite its high power and torque output, the motor operates with ultra-low noise levels. This is particularly beneficial for indoor environments such as postal logistics centers and food processing facilities.
Reliable Thermal Management and Safety
Equipped with an oil-immersed cooling system, the DM216 dissipates heat efficiently even during continuous operation. The motor includes a built-in thermal protector and Class F insulation, ensuring longevity and reliability. For uphill or inclined applications, an optional backstop can be integrated without increasing the drum's minimum length, providing an added layer of safety.
Global Compatibility and Standards
Designed for the global market, the DM216 is CE-certified and compatible with universal voltages at 50Hz or 60Hz. It offers an IP67 protection rating, making it completely dust-tight and capable of withstanding immersion in water. This level of protection is vital for agricultural plants and food processing lines that require frequent cleaning.
Customization and Minimal Maintenance
We provide extensive customization to meet specific project needs, including adjustable belt speeds and drum lengths. The DM216 arrives pre-filled with oil, and the specialized design allows for a long service interval of 50,000 operating hours between oil changes. Standard shells are available in galvanized carbon steel or 304 stainless steel with anti-slip threads for maximum belt traction.
