Product Overview
The Omron R88M-K40030T-S2 is a 400 W Accurax G5 AC servo motor from the R88M-K series, 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 delivers 400 W at 3000 rpm rated speed (6000 rpm max) with 1.3 Nm rated torque and 3.8 Nm peak torque. The 17-bit absolute encoder with battery backup needs no homing routine on power-up. The T suffix means the motor has a brake, an oil seal, a key shaft, and a shaft tap. The flange is 60 mm square and the shaft is 14 mm diameter.
The motor pairs with the R88D-KN04H-ECT-Z (EtherCAT), R88D-KN04H-ML2 (Mechatrolink II), or R88D-KT04H-Z (analog / pulse) G5 servo drive. Use the R88A-CAKA power cable and R88A-CRKA encoder cable. The motor is IP65 and weighs about 1.2 kg. For a no-brake variant with the same 400 W class, pick the R88M-K40030H-S2.
Key Features
- Accurax G5 AC servo motor, 400 W at 200 VAC, 3000 rpm rated
- 17-bit absolute encoder with battery backup, no homing on power-up
- T suffix = brake + oil seal + key shaft + shaft tap
- Pairs with R88D-KN04H-ECT, R88D-KN04H-ML2 or R88D-KT04H drive
- SKU: R88M-K40030T-S2
- Series: Omron Accurax G5-series AC servo motor
- Voltage: 200 VAC
Best-Fit Applications
- Vertical Z-axis on a packaging machine where the brake holds the load at power-off and the absolute encoder drops the homing routine
- Indexing conveyor where the key shaft couples to the gearbox and the oil seal keeps the gearbox oil out of the motor windings
- Spare drop-in for an existing G5 panel where the previous R88M-K40030T motor failed and the cabinet needs to keep the brake + key + oil seal
Buying Checklist
- Pick the R88M-K40030T-S2 for a 400 W G5 motor with brake, oil seal, key shaft and 17-bit absolute encoder.
- Pick the R88M-K40030H-S2 instead when the cabinet does not need the brake.
- Pick the R88M-K40030H-S2-Z instead when the cell needs a smooth shaft with absolute encoder but no brake.

FAQ for R88M-K40030T-S2
What does the T suffix mean on the R88M-K40030T-S2?
T marks the G5 motor as having a brake, an oil seal, a key shaft and a shaft tap. The brake is a 24 VDC spring-set / electromagnetic-release brake used to hold the load when the drive is off.
Which drive pairs with the R88M-K40030T-S2?
Three G5 drives match: the R88D-KN04H-ECT (EtherCAT) for Sysmac NJ / NX control, the R88D-KN04H-ML2 (Mechatrolink II) for CJ2 / CS1 control, and the R88D-KT04H (analog / pulse) for stand-alone or CP1 / CP2E control.
Does the R88M-K40030T-S2 need a homing routine?
No. The 17-bit absolute encoder with battery backup remembers the shaft position across power cycles, so the absolute position is valid at every power-up without a homing move. Replace the encoder battery every 3 years or when the drive reports a low-battery warning.
