Overview
The ECOSTEP 23S21-0560 is a compact rotary servo motor in the ECOSTEP 23S series, engineered for dynamic motion in NEMA 23 axes. Featuring a 56 mm flange and 87 mm motor length, it delivers 0.5 Nm rated torque at 1000 min⁻¹ and supports speeds up to 3000 min⁻¹.
Standard protection is IP40, with an optional IP65 housing available (shaft gland remains IP40). Extensive mechanical options, including holding brakes, gear stages, and various shaft or flange variants, allow the 23S21-0560 to be precisely matched to the machine mechanics and recommended JAT servo amplifiers.
Advantages
The ECOSTEP 23S21-0560 supports dynamic servo axes in space-constrained machines.
- When high torque at low speed and precise control are required, ECOSTEP motors provide a cost-efficient alternative to traditional servo motors.
- High torque at low speed: With 0.5 Nm rated and 0.99 Nm peak torque, this motor facilitates direct drive concepts, often eliminating the need for a gearbox.
- Dynamic servo behavior: A torque constant of 0.15 Nm/A and low rotor inertia enable efficient current control and accurate positioning.
- Flexible configuration: Options for encoders, brakes, and IP65 housing allow one motor type to cover multiple machine variants.
Where it fits
The ECOSTEP 23S21-0560 fits dynamic rotary axes in compact machines.
- Assembly and handling axes in electronics or small parts production
- Indexing and format adjustment drives in packaging and special machinery
- Rotary stages in laboratory and inspection equipment requiring repeatable positioning
Interfaces
The ECOSTEP 23S21-0560 is designed for straightforward integration into JAT drive systems at a 60 V DC link.
- Feedback interfaces: Incremental ABN, BiSS-B absolute, and SinCos encoders are available to meet different resolution requirements.
- System integration: Designed for ECOVARIO 114(D), ECOMODUL, and ECOMiniDual servo amplifiers. Matching connector sets and cable extensions ensure quick commissioning.
