1100 W continuous, 9 N·m holding brake — SH31002M12F1000 servo motor
The SH31002M12F1000 is a Schneider Electric SH3 series servo motor with an integrated holding brake, rated for 1100 W continuous power. The brake delivers 9 N·m holding torque, which means the motor holds its position on a vertical axis without a separate mechanical lock — the brake is sized for the full rated load. Nominal speed depends on the supply voltage: 500 rpm on 115 V single-phase, 1000 rpm on 230 V single-phase, 2000 rpm on 400 V three-phase, and 2400 rpm on 480 V three-phase. The nominal torque also shifts with voltage — 5.62 N·m at 115 V single-phase, 5.28 N·m at 400 V three-phase — so the application voltage directly sets the usable torque-speed envelope. Peak stall torque reaches 18.3 N·m across the 115...480 V three-phase range, giving headroom for acceleration transients. Continuous stall torque is 5.8 N·m over the same voltage band, which defines the thermal limit for sustained positioning or tensioning applications.
Absolute multiturn Hiperface encoder — no homing cycle needed
The motor carries an Absolute multiturn SinCos Hiperface encoder. This encoder type reports absolute position over multiple shaft revolutions, so the drive knows the rotor angle at power-up without a homing sequence — critical for applications where the machine must resume operation after a power cycle without re-referencing. The encoder signal is SinCos (analog sine/cosine) with Hiperface protocol, compatible with Schneider Electric Lexium drives and third-party drives that support the Hiperface interface. The multiturn resolution is set by the encoder manufacturer; typical values are 4096 revolutions with 1024 sine/cosine periods per revolution.
IP65 motor body, natural convection cooling
The motor achieves IP65 protection when the shaft bushing includes the shaft seal ring, per IEC 60034-5. Without the seal ring, the shaft bushing is IP54. This means the motor body withstands washdown environments — suitable for food processing or wet machining lines — but the shaft seal must be verified for the specific installation. Cooling is by natural convection — no external fan or forced air. The continuous torque rating assumes free airflow around the motor body; derating applies if the motor is enclosed or mounted in a confined space with restricted convection.
The motor is part of the SH3 series, which shares the same flange size (100 mm) and centring collar diameter (95 mm) across the family. If a different power or speed variant is needed, the SH31002M sizing reference indicates the mechanical footprint is consistent — the mounting holes and shaft dimensions (19 mm diameter, 40 mm length with parallel key) are common across the series.
