Why Engineers Specify This Model
- High Torque Density – 6.37 N·m continuous torque in a compact 130 mm frame reduces machine footprint without sacrificing performance.
- 17-Bit Encoder Precision – 131,072 counts per revolution enables sub-arc-minute positioning, critical for robotic and CNC applications.
- IP67 Sealing – Full dust-tight and water-immersion protection makes it suitable for washdown environments in food processing and pharmaceutical lines.
- Seamless Delta Ecosystem Integration – Plug-and-play compatibility with ASDA-B2/A2/A3 drives eliminates parameter tuning complexity and reduces commissioning time.
- Low Cogging Torque – Smooth rotation at low speeds ensures consistent surface finish in grinding and polishing applications.
- Wide Speed Range – 1:5000 speed ratio supports both ultra-low creep speeds and full 3000 RPM operation within a single axis.

Application-Specific FAQ
Q: Is the ECMA-E21320SS compatible with the EX160-SDN1A robot arm?
A: Yes. The EX160-SDN1A is a Delta 6-axis industrial robot that uses ECMA-E series servo motors on its primary axes. The ECMA-E21320SS is a documented replacement motor for this platform.
Q: What is the difference between ECMA-E21320SS and ECMA-E21320RS?
A: The suffix “SS” denotes a standard shaft with keyway and IP67 oil seal. “RS” typically indicates a reduced-shaft or application-specific variant. Confirm your robot arm’s motor mount specification before ordering.
Q: Can this motor be used with a non-Delta drive?
A: The ECMA-E21320SS uses Delta’s proprietary 17-bit encoder protocol. While the motor windings are compatible with generic servo drives, full encoder functionality requires a Delta ASDA-series drive or a third-party drive with Delta encoder support (e.g., via SSI or BiSS-C adapter).
Q: What is the lead time for this part?
A: In-stock units ship within 1–3 business days. For bulk orders or units requiring factory-new certification, lead time is 2–4 weeks. Contact us for real-time stock confirmation.
Q: Do you provide a warranty?
A: All units sold by Konmask.com carry a 90-day functional warranty covering encoder failure, winding defects, and bearing noise. Warranty excludes physical damage caused during installation.
