Model Naming (EPS-RH Series Naming Conventions)

Naming example shown: EPS - RH - 17 - 100 - E - B - D

  • EPS: Brand Name (E = Efficiency, P = Precision, S = Smart)
  • RH: Series Name (Harmonic Actuator)
  • 17: Harmonic Model (e.g. 14/17/20/25/32 etc)
  • 100: Reduction ratio 100:1
  • E: Communication (E: CAN BUS & EtherCAT)
  • B / N: Brake option (N: Without Brake, B: With Brake)
  • D / S: Encoder option (D: Dual Encoder, S: Single Encoder)

Example model shown: EPS-RH-20-100-E-N-D
