ECMA Servo Motors

ECMA Servo Motors The ECMA is Delta's general purpose, permanent magnet servo motor series. The ECMA series is plug-n-play with our A2 Intelligent or B2 Economy servo drives.


This series of Servo motor is available from 50W to 15kW. The ECMA servo motor series is a state of the art Servo motor. Its segmented stator results in low flux loss. The case and bearings are designed to withstand 2.5Gs of vibration. Rare earth magnets, Neodymium-Iron-Boron (NeFeB) are used in the rotor for high torque to size ratio. Delta's ECMA motor series is 10 pole design (unlike the more common 6 or 8 pole) and delivers low cogging and smoother motion than other servomotors on the market.

Performance of the ECMA servo motor in combination with Delta's Servo Drives is outstanding.


  • Maximum torque is on the order of 300% of rated.
  • Peak speed is as high as 5000rpm.
  • Multiple Shaft options are available.
  • Both Incremental and Absolute (Multi Turn) encoders.
  • Other options like a holding brake, spring loaded oil seal, and IP67 connectors adds even more value and flexibility to this servo motor series.
