01 / Overview

750 W 100 V 1S servo motor without brake

The Omron R88M-1M75030T-S2 is a 750 W, 100 VAC, 3000 rpm member of the 1S-series servo motor family, without a brake. The "1M" prefix denotes the 100 V class; "75030" is 750 W at 3000 rpm; "T" is the standard (non-oil-seal) shaft; "-S2" denotes a smooth shaft without brake.

The 1S family is Omron's compact, low-cost servo motor line for the 1S-series drives. It uses a 17-bit incremental serial encoder, and the motor body has a 50 mm or 80 mm square flange depending on the power rating. The 750 W model is in the 80 mm frame.

The no-brake version is intended for horizontal-axis applications where the load does not need to be held when the servo is de-energised — conveyors, rotary indexers, lead-screw-driven linear axes on horizontal travel. For vertical or Z-axis applications, choose the -BS2 brake version.

The 100 V class is common in Japan and on small 100 V control transformers. In Europe and the Americas, the 200 V class is the standard.

Typical Applications

  • Mid-power horizontal-axis motion on packaging lines
  • Conveyor drives and rotary indexers
  • Lead-screw-driven linear axes on horizontal travel
  • Labelling heads and small-format assembly stations
  • Material-handling equipment in light-duty cells

Buying Checklist

  • Match the motor voltage class (100 V) to the drive voltage class — never mix
  • For vertical-axis / Z-axis applications, choose the -BS2 brake version instead
  • For keyed shaft, choose the -S2K variant; for oil seal, add the O-seal suffix
  • Use a flexible coupling rated for the 14 mm shaft and your side-load
  • The matching drive is the R88D-1M75030T-S2 in the 100 V family

03 / FAQ

Frequently Asked Questions

What drive pairs with this motor?

The R88D-1M75030T-S2 (EtherCAT) in the 100 V 750 W family. For MECHATROLINK-II, use the R88D-1M75030T-ML2 (or the current 1S-series ML2 drive if still active in your region).

Why is this version brake-less?

Horizontal-axis duty — conveyors, rotary indexers, lead-screw-driven axes where the load does not need to be held when the servo is off. For vertical / Z-axis applications, use the -BS2 variant, which has a spring-applied 24 VDC brake.

Can I add a brake later?

No — the brake is built into the motor at the factory. If you think you might need a brake, buy the -BS2 version from the start; retrofitting is not possible.
