Product Overview
The Omron R88M-1M40030T-S2 is the 400 W low-inertia AC servo motor in the 1S-series (R88M-1M family). 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.
It runs at 3000 rpm rated speed with a 60 mm square flange, carries an incremental 23-bit encoder, and ships with a straight connector and oil seal. The rotor inertia is 0.0384 x 10-4 kg.m^2, so the motor accelerates and decelerates quickly - the right pick for point-to-point positioning and high-throughput conveyor indexing.
For 200 V applications where the motor must run at higher peak torque, the R88M-1M75030T-S2 carries the same frame with 750 W rated. Key specs: Model R88M-1M40030T-S2; Rated Power 400 W; Rated Speed 3000 rpm; Flange Size 60 mm square; Rotor Inertia 0.0384 x 10-4 kg.m^2 (low inertia); Encoder Incremental 23-bit; Shaft End Straight with key, oil seal; Compatible Drive R88D-1SN04H-ECT (EtherCAT, 200 V).
Key Features
- R88M 1S-series 400 W low-inertia AC servo motor, 3000 rpm rated
- 60 mm square flange, 0.0384 x 10-4 kg.m^2 rotor inertia
- Incremental 23-bit encoder, oil seal, straight connector with key
- Pairs with R88D-1SN04H-ECT EtherCAT drive; same 60 mm flange as 200 W / 750 W siblings
- SKU: R88M-1M40030T-S2
- Series: R88M 1S-series AC servo motor (1M low-inertia family)
Best-Fit Applications
- Point-to-point pick-and-place on a packaging line where 400 W at 3000 rpm drives the indexing conveyor.
- OEM machine retrofit where the 1S-series drive replaces a legacy Sigma-II drive on the same motor frame.
- Filling-line capper spindle where the low-inertia motor matches the cap-feeding cam.
Buying Checklist
- Choose R88M-1M40030T-S2 when 400 W at 3000 rpm is the right size for the load inertia.
- Choose R88M-1M20030T-S2 (200 W) for the same 60 mm flange with lower power.
- Choose R88M-1M75030T-S2 (750 W) for higher torque on the same flange.

FAQ for R88M-1M40030T-S2
What is the difference between R88M-1M40030T-S2 and R88M-1M40030T-BS2?
The -S2 is the straight connector with key. The -BS1 / -BS2 variants add an electromagnetic holding brake (24 VDC). The -B in BS means brake; the trailing number 1 or 2 marks the connector style. Pick the BS variant when the load must hold position when the servo is de-energised (vertical axis, suspended load).
What drive pairs with the R88M-1M40030T-S2?
The R88D-1SN04H-ECT EtherCAT drive on a single-phase or three-phase 200 V supply. The drive reads the motor ID at power-on and sets the encoder resolution and motor parameters automatically - no manual commissioning needed in Sysmac Studio. The export tool converts screens, alarms, and tags - some advanced scripting elements may need manual adjustment after the conversion.
What is the rotor inertia of the R88M-1M40030T-S2?
0.0384 x 10-4 kg.m^2 (low-inertia 1M family). The rule of thumb is load inertia should be 1 to 3 times motor inertia; for 400 W applications that gives roughly 0.04 to 0.12 x 10-4 kg.m^2 of acceptable load inertia.
Can the R88M-1M40030T-S2 run on a Sigma-II drive?
No. The 1S-series motor uses a 23-bit incremental encoder with a different protocol than the legacy Sigma-II 17-bit absolute encoder. Pair it with the R88D-1SN-ECT or R88D-KN-ECT drive for EtherCAT motion. Industrial CF cards include wear-levelling and extended-temperature ratings that consumer cards lack for cabinet duty.
