The Omron R88M-1M20030S-BS2 is a 200 W cylindrical servo motor from the 1S Servo System family, spinning at 3000 rpm on a 120 VAC single-phase supply. It carries an absolute encoder and an integrated brake — the brake holds the load at power-off, which matters for vertical-axis applications where a dropped load means a crash or a scrap part.
The 200 W capacity and 3000 rpm top speed place this motor squarely in the small-frame, high-speed class — think pick-and-place, labeling, or small indexing tables where cycle time matters more than torque. The absolute encoder eliminates the need for a home-find sequence on every power-up; the drive knows the shaft position as soon as the bus comes up. That saves a few seconds per cycle on machines that power-cycle between batches. The brake is a holding brake, not a dynamic braking resistor. It holds the load stationary when the drive is disabled, but it is not rated to stop a moving load in an emergency-stop scenario. If your application needs to decelerate a high-inertia load quickly, you still need a dynamic braking resistor on the drive side. Key and tap on the shaft means the motor can transmit torque through a keyway rather than relying on a friction fit. That is standard for most servo applications, but worth confirming if your coupling uses a collet-style clamp that expects a smooth shaft.
