EI7., EI8. built-in encoder

The built-in encoders from SEW‑EURODRIVE are completely integrated into the motor. This means the overall length of the drive remains unchanged. The components of the built-in encoder do not protrude beyond the contour of the drive, which means they are particularly well protected from environmental effects and damage. Built-in encoders enable a particularly compact motor design.

Areas of application

EI7. built-in encoders are suitable for the following applications:

  • Simple positioning with up to 96 increments per revolution
  • Speed monitoring
  • Direction of rotation monitoring
  • The EI7C encoder is also available as an EI7C FS safety encoder (not on size DR.63..).

EI8. built-in encoders are suitable for the following applications:

  • The EI8Z built-in encoder allows for a motor without additional length due to the encoder in combination with single-cable technology and the fully digital MOVILINK® DDI interface.
  • Speed monitoring
  • Direction of rotation monitoring
  • Positioning/position control up to a resolution of 12 bits (4096 increments/revolution)
  • Speed control
  • Torque control
