9. How does the motor's frame size (130mm) relate to its performance?

The 130mm frame size indicates the motor's physical dimensions, specifically the diameter of the motor's stator. Generally, larger frame sizes denote motors with higher power and torque capabilities due to increased copper windings and magnetic material. The EM3G-13ALA224’s 130mm frame size is appropriate for its 2.2kW power rating.

This frame size ensures sufficient space for robust internal components necessary for high precision and torque. It contributes to the motor's ability to dissipate heat effectively, maintaining performance under load. It’s a key indicator of the motor's power density.

When selecting a servo motor, the frame size is important for mechanical integration into existing machinery. It needs to fit within the available mounting space while providing the required performance.

10. What are the advantages of using an incremental encoder compared to an absolute encoder in this motor?

Incremental encoders, like the one in the EM3G-13ALA224, are cost-effective and offer high resolution for precise speed and position control during operation. They provide detailed feedback on movement, which is ideal for continuous motion applications. Their simplicity often leads to higher reliability in some industrial scenarios.

When power is lost, an incremental encoder loses its position reference and requires a re-homing procedure upon startup. This is achieved using limit switches or index pulses. This process is standard in many automated systems.

For applications where maintaining position across power cycles is critical without re-homing, an absolute encoder would be preferred. However, for many typical industrial automation tasks, the 2500-line incremental encoder offers a superior balance of performance and cost.
