Motor frame and mounting dimensions
The SH31002M11F1000 uses a 100 mm flange with a 95 mm centring collar and 3.5 mm collar depth. Four mounting holes on a 9.0 mm diameter pattern — confirm the mating face on your gearbox or machine frame matches this bolt circle before committing the BOM line. Overall length is 235.5 mm with a 19 mm shaft diameter and 40 mm shaft length terminated in a parallel key with 6 mm key width. The straight connector exits axially — plan cable clearance behind the motor.
Torque and speed across supply voltages
This is a three-phase servo motor whose nominal speed depends on the supply you feed it: 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 holds fairly flat across the range — 49.74 lbf.in (5.62 N.m) at 115 V single-phase down to 46.73 lbf.in (5.28 N.m) at 400/480 V three-phase. Continuous stall torque is 5.8 N.m across the 115-480 V three-phase range, with a peak stall torque of 18.3 N.m available for acceleration transients. The 9.0 A RMS continuous current matches the 3-second peak current rating — the drive sizing should account for the RMS thermal limit, not just the peak.
Encoder and feedback for position loops
The absolute single-turn SinCos Hiperface encoder gives position feedback on power-up without a homing cycle — critical for applications where the axis must know its location immediately after a power loss or emergency stop. The SinCos analog tracks give the drive fine interpolation within one electrical revolution. Back EMF constant is 146 V/krpm at 20 °C; the torque constant is 2.32 N.m/A at 120 °C copper temperature. These two constants let the drive estimate motor temperature from the voltage/current relationship during operation.
Holding brake and mechanical load limits
Maximum radial force Fr is 990 N at 1000 rpm, derating to 620 N at 4000 rpm. Maximum axial force Fa is 160 N. These limits govern belt-drive or direct-coupling selections — overshoot them and the bearing life drops sharply.
Cooling and environmental sealing
Natural convection cooling means no external fan — the motor relies on its own surface area and airflow in the cabinet. The copper hot temperature limit is 130 °C; the stator resistance of 8.6 Ohm and inductance of 24.3 mH set the thermal time constant for overload protection in the drive. IP54 with the shaft bushing without shaft seal ring; IP65 with the shaft bushing. If the motor sits in a washdown zone, specify the IP65 configuration — the seal ring keeps coolant out of the bearing cavity.
Sourcing and lifecycle status
The sizing reference is SH31002M — use this when cross-referencing drive parameters or ordering mating connectors. No official successor or direct replacement part number has been published.
