Overview
The ECOSTEP 23S16-0560 is a high-performance rotary servo motor in the ECOSTEP 23S series, designed for dynamic motion with a compact NEMA 23 (56 mm) flange. With a motor length of 73 mm and a mass of approximately 0.9 kg, it delivers high torque density for this performance class.
Operating at a 60 V DC link, the 23S16-0560 provides 0.36 Nm rated torque at 1500 min⁻¹ and approximately 57 W rated power. This performance supports demanding motion profiles within the operating range. Standard protection is IP40, with an optional IP65 housing available for environments requiring higher protection (shaft gland remains IP40). Mechanical options, including shaft and flange variants, encoder systems, and connector configurations, allow precise adaptation to the application and the JAT servo amplifiers used in the axis.
Advantages
The ECOSTEP 23S16-0560 delivers NEMA 23 servo performance in a space-saving format.
- When high torque at low speed and precise control are required, ECOSTEP motors provide a cost-efficient alternative to traditional servo motors.
- Compact power density: High torque relative to the 56 mm flange and 73 mm length saves installation space.
- Direct drive capable:0.5 Nm peak and 0.36 Nm rated torque enable direct drive concepts, eliminating the need for a gearbox in many use cases.
- High dynamics: Genuine servo operation supports fast start-stop motion and precise positioning.
- Adaptable configuration: Multiple mechanical options, shaft and flange variants, and encoder choices allow the motor to match specific mechanics and control setups.
Where it fits
Use this compact rotary servo motor when installation space is limited and NEMA 23 torque and dynamics are required.
- Highly dynamic axes in assembly and handling systems
- Packaging and indexing applications with fast, repeatable positioning
- Medium-sized pick-and-place units or format adjustment axes in automation equipment
- Rotary actuators in laboratory, analysis, or inspection devices
- Compact servo axes in special machinery where high torque is required in a manageable footprint
These are application examples and do not imply specific industry approvals.
Interfaces
The ECOSTEP 23S16-0560 supports 24 to 60 V DC link operation and is optimised for use in JAT drive systems.
- Feedback systems: Incremental encoder as standard with 8,000 to 160,000 increments per revolution. Absolute and SinCos encoder options allow individual resolutions up to 256,000 inc/rev and up to 19-bit single turn.
- Options: Optional holding brake or gearbox, shaft and flange variants, and an IP65 housing option (shaft gland remains IP40).
- System integration: Recommended servo amplifiers include ECOVARIO 114D, ECOMODUL, and ECOMiniDual. Matching connector sets and pre-assembled cable extensions support reliable wiring and quick commissioning.
