What this motor is built for
The SH30553P02F1000 is a 55 mm flange servo motor from Schneider Electric's SH3 series, designed for precise motion control in applications that need a holding brake. It carries a smooth shaft and an absolute multiturn SinCos Hiperface encoder, so the drive knows the exact position on power-up — no homing cycle needed after a power loss or emergency stop. The holding brake delivers 0.8 N.m of holding torque, enough to keep a vertical axis from dropping when the drive is disabled. Three-phase supply, but the torque you get depends on the line voltage: 1.13 N.m at 115 V single phase, 1.1 N.m at 230 V single phase, and 0.81 N.m at 400 V or 480 V three phase. The continuous power rating is 680 W, and the nominal speed range runs from 2000 rpm at 115 V up to 8000 rpm at 400 V or 480 V three phase.
Encoder and feedback — what the Hiperface means
The absolute multiturn SinCos Hiperface encoder is the key differentiator here. Unlike an incremental encoder that loses position when power cycles, this one keeps track of the shaft angle across multiple revolutions. That means on a pick-and-place gantry or a rotary table, the controller knows exactly where the load is the instant the drive enables — no reference run, no lost production time after a fault. The SinCos analog track gives high-resolution position feedback for smooth low-speed control, and the Hiperface protocol is a common standard across Schneider's Lexium drives. If you're pairing this motor with a Lexium 28 or 32 drive, the feedback wiring is straightforward — just match the pinout in the drive manual.
Mounting and environmental fit
The motor mounts on an international standard 55 mm flange (2.2 in) with a centring collar diameter of 40 mm and a 2 mm collar depth. Four mounting holes at 5.5 mm diameter — standard bolt pattern for this frame size. IP54 with the shaft bushing without seal ring; IP65 with the seal ring fitted. That means it handles dust and splash in a typical machine environment, but if you're in a washdown zone, you'll want the seal ring option. Cooling is natural convection — no fan, so keep the ambient airflow in mind if you're running near the torque limit continuously.
Sourcing and lifecycle — active and available
We source SH30553P02F1000 through authorized distribution channels. No minimum order quantity beyond what the line allows — single-unit spares or production volumes, both quoted the same way.
