Streamlining Motion Efficiency: The Case for Direct-Drive Technology

The Downside of Traditional Powertrain Systems

Traditional servo drive and gearbox combinations have been a mainstay in industrial applications for years. However, in scenarios where rapid, repeated movements are critical, like one requiring a 100-millisecond motion every second, these systems show their limitations.

• Major energy consumption is due to moving the bulky components rather than performing the required work.
• Additional wear and complexity reduce system reliability over time.

Introducing Direct-Drive Rotary Motion Technology

Direct-drive technology, such as the innovative One Motion’s MagDrives (opens in a new tab), is designed to streamline processes by eliminating unnecessary components. By directly connecting the motor to the application, this technology offers several advantages:

“Direct-drive rotary motion systems minimize energy waste by focusing solely on the necessary output, thus enhancing overall efficiency.”

• Reduces the complexity and weight of the assembly.
• Increases energy efficiency, leading to cost savings.
• Decreases mechanical failure risks due to fewer moving parts.

Revolutionizing Rotary Motion: Why Direct Drive Matters

Say goodbye to gearboxes and hello to simplicity. One Motion’s MagDrive direct drive technology is changing the game for rotary motion. Traditional AC motors with gearboxes bring complexity, maintenance, and contamination risks. Our solution delivers:
