Consult Delta's product documentation or contact their technical support to confirm precise compatibility if using with non-ASDA-B3 drives.

Q7: What is the significance of "medium inertia" for this servo motor?

"Medium inertia" indicates a balance between the motor's resistance to changes in rotational speed and its ability to accelerate quickly. It's a compromise between low inertia motors (faster acceleration but potentially less torque) and high inertia motors (more torque, slower acceleration).

This characteristic makes the ECM-B3M-K21310RS1 versatile for applications that require both rapid movements and steady, controlled operation. It's suitable for many common industrial automation tasks.

For applications demanding extremely fast response, low inertia might be preferred. For high-force, slower applications, high inertia could be more suitable. Medium inertia offers a broad operational range.

Q8: How does the 24-bit encoder resolution benefit the system?

A 24-bit encoder provides a very high resolution for position feedback. This translates to extremely precise positional accuracy and smoother motor control.

High resolution allows the servo system to detect and correct minute deviations, leading to improved repeatability and reduced tracking errors in complex motion profiles.

This level of detail in feedback is essential for applications like precision grinding, laser cutting, or intricate robotic manipulation where micro-level accuracy is paramount.

Q9: What are the power and voltage specifications relevant to the ECM-B3M-K21310RS1?

The motor itself has a 1 kW power output. The compatible ASDA-B3 servo drive typically operates on a 200-230V AC input, often supporting both single-phase and three-phase power.

While the motor's input voltage is listed as 110V, the actual power delivery and control are managed by the servo drive, which handles the main power supply connection.

Always ensure the servo drive's power supply specifications match your facility's electrical infrastructure for safe and efficient operation.

Q10: Does this servo motor include a brake?

The Delta ECM-B3M-K21310RS1 servo motor, as specified by the model number and commonly listed, does not include an electromagnetic brake. This is indicated by the "without brake" designation in its specifications.

Motors without brakes are suitable for applications where external holding mechanisms are used or where the motor will not be subjected to gravitational loads when power is off. The absence of a brake can sometimes reduce the overall length and cost of the motor.

If a holding brake is required for an application (e.g., vertical axis loads), a different model with a brake option should be selected, or an external braking system should be incorporated.
