Product Overview
The Omron R88M-1M05030T-S2 is a 1S-series 50 W AC servo motor with a 23-bit battery-free absolute encoder and a 24 VDC electromagnetic brake It is 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.
The motor runs on 230 VAC single-phase and reaches 3000 rpm rated speed with 0.159 Nm rated torque and 0.56 Nm peak torque. The 23-bit encoder is battery-free, so no backup cell is needed.
The M05030H-S2 sibling drops the brake for horizontal axes; the M05030T-BS2 has the brake but a straight, non-keyed shaft. Key specs: Rated Output 50 W (0.05 kW); Rated Speed 3000 r/min; Rated Torque 0.159 Nm; Peak Torque 0.56 Nm; Drive Supply 230 V single-phase; Encoder 23-bit absolute without battery; Brake 24 VDC electromagnetic brake (T); Shaft / Flange 8 mm keyed shaft with tap, oil seal, 40 mm flange (S2).
Key Features
- 1S-series 50 W AC servo motor, 3000 rpm, 0.159 Nm rated torque, 0.56 Nm peak
- 23-bit battery-free absolute encoder, no battery to replace on the machine
- 24 VDC electromagnetic brake for vertical-axis hold, keyed shaft with tap and oil seal
- 40 mm flange, 8 mm shaft, 230 VAC single-phase supply, pairs with R88D-1SN02H-ECT drive
- SKU: R88M-1M05030T-S2
- Series: 1S-series AC servo motor
Best-Fit Applications
- Spare replacement on a legacy 1S line where the original motor failed and the new unit drops onto the same R88D-1SN02H-ECT drive and encoder cable
- Vertical-axis Z stage on a pick-and-place cell where the 24 VDC brake holds the head at power-off and the absolute encoder skips home-return on restart
- Compact labelling head where 50 W covers the label feed and the keyed shaft couples directly to a small gearhead
Buying Checklist
- Choose the R88M-1M05030T-S2 when the 50 W axis is vertical and needs the brake for power-off hold.
- Choose the R88M-1M05030H-S2 instead when the 50 W axis is horizontal and the brake is unnecessary mass.
- Choose the R88M-1M20030T-S2 instead when the same EtherCAT drive covers a larger 200 W axis with brake and keyed shaft.

FAQ for R88M-1M05030T-S2
Does the R88M-1M05030T-S2 have a brake?
Yes. The T suffix marks the 24 VDC electromagnetic brake. The brake needs a separate 24 VDC supply and is wired through the brake leads on the power cable. For a brake-less 50 W motor, pick the R88M-1M05030H-S2 sibling instead.
What drive pairs with the R88M-1M05030T-S2?
The R88D-1SN02H-ECT 1S EtherCAT drive (100 W class). It is the smallest 1S drive and matches this 50 W motor on a 230 VAC single-phase supply. Power cable R88A-CA1A003SFR (3 m) and encoder cable R88A-CR1A003CF-E (3 m) round out the bundle.
Is the encoder on the R88M-1M05030T-S2 absolute?
Yes, 23-bit, battery-free absolute. No backup battery is needed in the machine, which removes a maintenance item and lets the drive read the absolute position on the very first scan after every power-on of the system on startup of the rig.
What does the S2 suffix mean on this motor?
S2 marks the shaft and sealing option: keyed shaft with tap plus oil seal. The shaft-only R88M-1M05030T drops the key and seal entirely; the R88M-1M05030T-BS2 has the brake but a straight, non-keyed shaft for use with a flexible jaw coupling.
