EWDBInnovative synchronous servomotor

Featuring an integrated drive control unit, this synchronous servomotor combines compact dimensions with space-saving machine design and optimized wiring.
  • The low-voltage power supply (from 24 to 60 Vdc) simplify the connections structure of the axis with simple connectors.
  • 4 IP65 industrial water-resistant metal connectors on the back, 2 on the top for fieldbus communication such as CANOpen or Profinet, and 2 on the bottom for I/O connection and power supply.
  • It can be used in different applications, from simple implementation functions to complex controls.
  • Based on motors with 60 mm flange, stall torque from 0.7 to 1.3 Nm with and without integrated gearbox.
  • No need to downgrade the unite in terms of performance or power delivered to the motor.
  • Thanks to the integrated SinCos feedback, the product has good speed accuracy and position control.
  • Easy commissioning thanks to the complete characterization of the motor.


These are EWD B main features:

  • Feedback: SinCos Encoder or Halls Sensor (mi da conferma Carlo)
  • Fieldbus: CAN DS402 or Profinet IO or ETHERNET IP
  • 4 digital Inputs
  • Protection Level: IP65
  • Easy set-up
