In modern milling systems, roller motors play a crucial role in delivering stable, high-quality grinding performance. A precise and consistent torque ensures uniform particle size, energy efficiency, and extended machine life.
Following the grinding stage, feeder motors control the flow of raw grain into the rollers. A steady and accurate feeding process is essential for maintaining grinding consistency and process stability.

EMF Motor is a global manufacturer of advanced Direct Drive Technology, supporting OEMs and industrial users worldwide.
Our SQM Series is a brushless permanent magnet synchronous motor built on a patented direct drive principle, delivering high torque at low speeds without a gearbox. Ideal for both roller and feeder drives, these motors eliminate the need for mechanical transmissions and water cooling.

ROLLER MOTOR

• Direct Drive Without Water Cooling
Eliminates the need for a long belt drive and does not require additional floor space for the motor.
• Energy Efficiency
Achieves 15% to 70% energy savings compared to conventional systems.
​• Fanless Operation
Available in certain power ranges without the need for an external fan.
• Maintenance-Free Operation
No regular maintenance required, reducing operational costs and downtime.
• Quiet Operation & Reduced Vibration
Absence of mechanical transmissions results in quieter performance and minimized vibration.
• High-Speed Stability
Ensures continuous grinding quality even at high speeds.
• Adjustable Speed & Motor Protection
Allows speed adjustments and prevents motor failures caused by power grid issues when used with its driver system.
• Maximum Reliability
Designed for high durability and long-term performance.
• Advanced Technology Integration
Thanks to permanent magnet technology and driver combination, the system supports easy adaptation, predictive maintenance,
machine communication, and AI integration.


FEEDER MOTOR

​• Direct Drive
Eliminates the need for a gearbox
• Full Torque from 1 rpm to 300 rpm
Delivers maximum torque across the entire speed range without the need for a gearbox.
• Fanless Operation
Operates without an external fan, depending on the power range.
• Energy Efficiency
Achieves up to 50% energy savings compared to conventional systems.
• Maintenance-Free Operation
No gearbox means no lubrication or maintenance, reducing downtime and costs.
• Servo-Class Performance
Offers precise control with a simple driver system.
• Minimal Failure Risk
Fewer mechanical parts mean reduced risk of failure.
• Durability
Long service life by preventing mechanical wear and tear.
• High-Performance Response
Prevents material buildup and clogging in the nozzle, ensuring continuous flow and effciency.
