Product Overview

The Omron R88M-K20030H-S2-Z is a 200 W AC servo motor in the Accurax G5 family, manufactured by Omron Corporation. Hengyixin Automation ships this drive from Xiamen with the matching motor or PSU pairing recommended in the related products row below.

Rated output is 200 W at 3000 rpm with 0.64 Nm rated torque and 1.91 Nm peak (300 percent of rated) for fast acceleration. The encoder is 20-bit incremental (1,048,576 pulses per revolution). The shaft is straight with a keyway (S2), no brake, and an oil seal (Z) for oily gearbox mounting.

The flange is 60 x 60 mm and the shaft is 11 mm. Weight is around 820 g. Drive supply is 230 V single phase. Operating temperature is 0 to 40 degC. Pair with an R88D-KN02H-ECT (EtherCAT) or R88D-KT02H G5 servo drive. For the same 200 W without oil seal, pick the R88M-K20030H-S2. For 400 W with oil seal, pick the R88M-K40030H-S2-Z. For 2 kW with oil seal, pick the R88M-K2K030H-S2-Z.

Key Features

  • Accurax G5 200 W servo motor at 3000 rpm, 0.64 Nm rated and 1.91 Nm peak torque
  • 20-bit incremental encoder (1,048,576 pulses per revolution), straight keyed shaft
  • Oil seal fitted (Z suffix) for gearbox mounting; no brake; 60 x 60 mm flange, 11 mm shaft
  • 230 V single-phase drive supply, 0 to 40 degC operating, 820 g, pairs with R88D-KN02H-ECT or R88D-KT02H
  • SKU: R88M-K20030H-S2-Z
  • Series: Omron Accurax G5 servo motor (R88M-K line)

Best-Fit Applications

  • Conveyor-tracking axis on a small-format packaging line driven by an R88D-KN02H-ECT over EtherCAT from an NJ101 controller
  • Index drum on a labelling machine where the gearbox sits in an oil-mist environment and the oil seal on the motor matters
  • Spare drop-in for an existing G5 200 W axis where the previous motor failed and the cabinet already has the matching R88D-KT02H analog drive

Buying Checklist

  • Pick the R88M-K20030H-S2-Z for a 200 W Accurax G5 servo motor with a 20-bit incremental encoder and an oil seal.
  • Pick the R88M-K20030H-S2 instead when the gearbox is dry and the oil seal is not needed.
  • Pick the R88M-K40030H-S2-Z instead when the load needs 400 W and the same oil-seal mounting arrangement.

FAQ for R88M-K20030H-S2-Z

What does the Z suffix mean on the R88M-K20030H-S2-Z?
Oil seal. The Z adds a lip seal on the shaft end so oil mist from a gearbox does not migrate into the motor bearing. It does not change the rating or the encoder.
Which servo drive pairs with the R88M-K20030H-S2-Z?
R88D-KN02H-ECT (EtherCAT), R88D-KN02H-ML2 (MECHATROLINK II), or R88D-KT02H (analog / pulse). All three are 200 V / 200 W class G5 drives from the same family.
Does the R88M-K20030H-S2-Z hold position after a power cycle?
No. The H suffix means 20-bit incremental encoder, so the absolute position is lost on power-down and the axis must home on every restart. For position retention without homing, pick the -T suffix (R88M-K20030T-S2-Z) with 17-bit absolute encoder and battery backup.
Is the R88M-K20030H-S2-Z a 2 kW motor?
No. The K20030 part of the SKU means 200 W, not 2 kW. The 2 kW sibling in the same family is the R88M-K2K030H-S2-Z, which uses the 100 x 100 mm flange and a 19 mm shaft instead of 60 x 60 mm and 11 mm.
