Motor specs that decide the fit
The SH31001M12F2200: This is a 660 W continuous power servo motor from the SH3 series, with a holding brake rated 9 N.m — enough to hold a vertical axis load at rest without power to the drive. The nominal torque varies with the supply: 2.8 N.m at 115 V single phase, 2.71 N.m at 230 V single phase, and 2.52 N.m at both 400 V and 480 V three phase. That means if you're running it on a 400 V three-phase line, you budget 2.52 N.m continuous — the motor doesn't deliver the same torque across all voltages. Peak stall torque is 9.6 N.m across the 115–480 V three-phase range — this is the torque available for acceleration during short bursts, not continuous. Continuous stall torque sits at 2.94 N.m over the same voltage range. The encoder is an Absolute multiturn SinCos Hiperface — no homing cycle needed on power-up; the position is known from the moment the drive enables. This saves a few seconds per cycle on machines that power-cycle between batches.
Mounting and mechanical interface
Flange size is 100 mm (3.9 in) with a centering collar diameter of 95 mm (3.7 in) and a depth of 3.5 mm (0.1 in) — this matches the standard IEC mounting pattern for 100 mm flange motors. The shaft is 19 mm diameter, 40 mm long, with a parallel key 6 mm wide — standard for coupling to a load via a bell housing or timing-belt pulley. IP65 on the motor body and shaft bushing, IP67 on the housing — the motor handles washdown spray but not submersion; the shaft seal is the wet-end barrier. Maximum radial force is 900 N at 1000 rpm, dropping to 530 N at 5000 rpm — if you're belt-driving a high-inertia load at speed, the bearing life depends on staying under this curve. Maximum axial force is 160 N.
Electrical parameters for drive tuning
Stator resistance is 13.9 Ω and inductance is 34.7 mH — these go into the drive's auto-tuning routine for current-loop gains. Maximum current Irms is 6.3 A; the 3-second peak current is also 6.3 A — the motor's thermal limit is the same for continuous and short-term overload, so the drive's current limit should be set at or below this value. Torque constant is 1.63 N.m/A at 120 °C copper temperature — this is the hot value; at cold start the torque per amp will be slightly higher until the windings warm up. Back EMF constant is 115 V/krpm at 20 °C. The motor has 4 poles, so the electrical frequency at 3000 rpm is 100 Hz — the drive's carrier frequency and filter settings should accommodate this.
