Behind every smooth bend and efficient cycle is a main motor that delivers the required energy to your press brake’s hydraulic or servo system. While traditional motors are still widely used, servo motors have taken center stage in modern bending environments.
⚙️ Traditional AC Motors
These are asynchronous induction motors that run at a constant speed when energized.
Common in older hydraulic press brakes
Simple design, easy to maintain
Always running when the machine is powered on
Limitations:
High idle energy consumption
Slower response for dynamic operations
Can lead to unnecessary noise and heat buildup
⚡ Servo Motors
Servo motors respond to digital signals from the CNC controller and adjust speed, torque, and position instantly.
Used in hybrid and electric press brakes
Only run during operation → energy saving
Excellent for high-speed or robotic lines
🔋 Key Comparisons
| Feature | Traditional Motor | Servo Motor |
|---|---|---|
| Energy Use | Always running | On-demand only |
| Noise | Constant | Quiet in idle |
| Accuracy | Limited | Precise torque control |
| Maintenance | Simple | Requires servo expertise |
🧠 Application Insight
In production environments with frequent bends, servo motors can save up to 30–50% energy, reduce oil temperature, and enable faster return speeds.
At Machnist, we offer both motor options across our product line. As an adaptive Machnist manufacturer, our Eco and Pro series use traditional motors for economy, while our Max and Ultra series integrate servo motors for performance and sustainability.
