Motor specs that decide the fit
The SH31004P1BA4100: Rated 2.5 kW continuous power, this SH3-series servo delivers 9.5 Nm nominal torque at 400 V three-phase, with a nominal speed of 3000 rpm — the torque drops to 7.9 Nm at 480 V and 6.9 Nm at 230 V single-phase, so the supply voltage directly sets the usable torque budget. Peak stall torque hits 40.5 Nm across the 115–480 V three-phase range, with a 32.3 A peak current draw — the stator inductance of 13 mH and resistance of 1.8 Ohm shape the winding time constant, which matters for the drive tuning loop.
Feedback and environmental sealing
Encoder is an absolute multiturn Hiperface DSL — single-cable feedback and power, which simplifies the cable management on the moving axis compared to a separate feedback cable. IP65 on both the motor body and the shaft bushing per IEC 60034-5, so the motor tolerates washdown and airborne particulates in food, packaging, or woodworking lines — the connector interface uses a straight connector, with a quick-lock rotatable right-angle option available.
Mounting and mechanical interface
Flange size is 100 mm (3.9 in) with an international standard flange pattern — centring collar diameter 95 mm, depth 3.5 mm, and four M9 mounting holes on the bolt circle. Shaft is 24 mm diameter, 50 mm length, with a parallel key 8 mm wide — the maximum radial force at the shaft nose is 145 N at 1000 rpm, dropping to 100 N at 3000 rpm, and axial force is limited to 20 N. Overall length is 276.5 mm (10.9 in) — does it drop into the old footprint? Measure the back-of-flange to fan cover clearance; the natural convection cooling means no fan shroud protrusion to account for.
