Sizing the SH31401M12F2100 to the axis duty
The SH31401M12F2100 delivers 1700 W continuous power with a continuous stall torque of 11.1 N.m across the 115...480 V three-phase range — this is the thermal baseline for the duty cycle, not the peak capability. Nominal speed shifts with supply: 1500 rpm at 400 V three-phase, 1800 rpm at 480 V three-phase, and drops to 375 rpm on 115 V single-phase or 750 rpm on 230 V single-phase. Match the drive input voltage to the line power available before locking in the speed-torque curve. Peak stall torque reaches 27 N.m — enough for acceleration transients in pick-and-place or indexing moves, but the 4 A continuous stall current sets the I²t limit for the drive's current loop tuning.
Encoder feedback and position retention
The absolute multiturn SinCos Hiperface encoder retains position across power cycles — no homing sequence on restart, which closes the cycle budget on machines that power-cycle between batches. The back EMF constant of 193 V/krpm at 20 °C sets the voltage ceiling for the drive's DC bus; at 4000 rpm maximum mechanical speed the generated voltage approaches 772 V line-to-line, so the drive's input stage must handle that back-EMF without saturating.
Holding brake for vertical-axis safety
The integrated holding brake delivers 23 N.m static torque — enough to secure a vertical load at standstill without servo hold current, which keeps the winding temperature down during dwell periods. The brake is factory-fitted; the motor nameplate carries the brake voltage rating so the control cabinet's 24 VDC brake supply can be wired without opening the motor connector.
Environmental sealing and mounting interface
IP65 per IEC 60034-5 on both the motor body and the shaft bushing — the seal holds up to washdown in food-and-beverage lines and wet machining coolant, but the connector end must be mated with the IP-rated cable set to maintain the rating. The 140 mm flange with 130 mm centring collar and 11 mm mounting holes bolts directly to standard IEC frame interfaces; the 24 mm shaft with parallel key and 8 mm keyway matches common coupling and pulley bores.
