The ECMA-K11315SS (ECMA-K11315SS) is a high-performance AC servo motor from Delta’s ECMA series, designed for industrial motion control applications requiring high torque and precise positioning. With a rated output of 1.5 kW and a rated speed of 2,000 r/min, this 130 mm frame motor is engineered for reliability in demanding environments such as automated manufacturing lines, high-speed indexing, and precision machinery. The "SS" shaft configuration—featuring a keyway, integrated electromagnetic brake, and oil seal—ensures secure mechanical coupling and protection against environmental contaminants.
This motor is built for 400 V industrial power systems and utilizes a 20-bit incremental encoder, providing high-resolution feedback (1,048,576 pulses/rev) necessary for sophisticated motion profiles. The inclusion of an integrated brake is a critical safety and operational feature, enabling the motor to hold position effectively when power is removed or during emergency stops. The robust 130 mm frame and oil-sealed shaft allow this unit to perform consistently in diverse factory floor settings, from clean-room assembly to more robust mechanical environments.

What is the advantage of the 20-bit incremental encoder?
The 20-bit encoder provides over 1 million pulses per revolution. This high resolution significantly improves the motor’s ability to perform precise speed regulation and fine-positioning tasks, reducing jitter and enhancing overall system smoothness.
Why is the electromagnetic brake included in this model?
The integrated brake is essential for vertical axis applications or systems where holding torque is required when the motor is de-energized. It prevents mechanical load drops during power-off states and ensures the system remains in a safe, locked position during stop cycles.
How does the oil seal benefit industrial applications?
The oil seal provides a vital barrier that prevents lubricants, dust, and moisture from entering the motor’s internal bearings. This is crucial for extending the motor’s service life in environments involving machining fluids or airborne particulates.
Mechanical Coupling: When mounting the motor to your mechanical load, ensure the drive shaft is perfectly aligned. For the keyway shaft, use a high-quality coupling to absorb minor misalignment and prevent excessive radial force on the bearings.
Wiring and Grounding: Always use Delta-specified motor power and encoder cables. The motor casing must be bonded to the servo drive’s grounding terminal using a dedicated ground wire to prevent electrical noise from interfering with the high-resolution encoder signals.
Brake Control: Ensure the servo drive is properly configured to control the internal brake. The brake is intended for holding, not for dynamic deceleration (braking the load while in motion), as this can cause premature wear on the friction surfaces.
