1100 W SH3 servo — supply-voltage-dependent performance
The SH31002M11A2200 is a 1100 W continuous-power servo motor from Schneider Electric's SH3 series, with a 100 mm flange and a parallel-key shaft (0.7 in diameter, 1.6 in length). Its nominal torque and speed are supply-voltage dependent: at 400 V three-phase it delivers 5.28 N·m at 2000 rpm, while at 480 V three-phase the same torque holds at 2400 rpm. On single-phase 230 V, torque drops to 5.5 N·m at 1000 rpm; on 115 V single-phase, it's 5.62 N·m at 500 rpm. The absolute single-turn SinCos Hiperface encoder eliminates the need for a homing sequence on power-up — the drive reads the absolute position immediately. This matters for applications where the machine must resume operation without a reference move after a power cycle.
Torque and overload — continuous vs peak
The 4-pole motor with stator resistance 8.6 Ω and inductance 70.2 mH sets the electrical time constant — expect the current loop to settle within a few milliseconds with a properly tuned servo drive. Maximum radial force derates with speed: 990 N at 1000 rpm, 790 N at 2000 rpm, 690 N at 3000 rpm, 620 N at 4000 rpm — belt or pulley loads must respect this envelope to avoid bearing overload.
Sealing and environmental rating
The motor carries IP65 on the body and shaft bushing, with IP67 on the housing per IEC 60034-5. In practice, the housing seal exceeds the body rating — the connector end is the wet-end barrier. The straight connector and rotatable right-angled connector are both sealed; the rotatable version allows cable exit orientation adjustment during installation without breaking the seal. Natural convection cooling means no fan — the motor relies on its surface area and the mounting flange for heat dissipation, so derate if enclosed in a non-ventilated cavity.
