The SH31402P01F2200 is a three-phase servo motor from the SH3 series, rated for 3.9 kW continuous power. At 400 V three-phase supply it delivers 3000 rpm nominal speed; at 480 V three-phase it reaches 3600 rpm. The motor also runs on single-phase supplies — 115 V yields 750 rpm, 230 V gives 1500 rpm — though at reduced output power. Holding brake is integrated, rated at 23 N.m holding torque. That means the motor holds the load in position when power is removed — no external brake resistor or mechanical lock needed for vertical-axis or palletizing applications. The nominal torque at 400 V three-phase is 12.3 N.m, with a continuous stall torque of 19.5 N.m across the 115...480 V three-phase range. Encoder is an absolute single-turn SinCos Hiperface type. Single-turn means the absolute position is tracked within one revolution — no homing cycle after power-up for rotary axes that don't need multi-turn counts. The SinCos Hiperface interface is common on Schneider drives, so it mates directly with Lexium 32 or similar servo drives without a separate encoder converter. IP65 rating on the motor body and shaft bushing per IEC 60034-5; the housing is IP67. The rotatable right-angled connector lets you orient the cable exit to clear the machine frame or guarding.
Mounting and mechanical integration
Mounts on an international standard flange, 140 mm (5.5 in) flange size. The centring collar is 130 mm diameter with a 3.5 mm depth, and the four mounting holes are 11 mm diameter — standard bolt pattern for this frame size. Smooth shaft, 24 mm diameter, 50 mm shaft length. Natural convection cooling — no fan or forced air required. That simplifies the enclosure design: no air intake grilles or filter maintenance, and the motor runs quieter. The copper winding hot-spot temperature is rated to 130 °C, so the thermal budget is generous for continuous-duty cycles.
Electrical parameters and drive matching
Stator resistance is 0.6 Ohm, stator inductance 11.225 mH — these set the electrical time constant and influence the current-loop tuning on the servo drive. Maximum current Irms is 44.1 A; continuous stall current is 13.2 A. The torque constant is 1.47 N.m/A at 120 °C winding temperature, so the drive's current limit directly sets the available torque. Back EMF constant is 101 V/krpm at 20 °C. At 3000 rpm the back EMF is about 303 V line-to-line — the drive's DC bus must be high enough to overcome this plus the IR drop. Maximum mechanical speed is 4000 rpm, so the motor can overspeed for short moves if the drive supports field weakening. Peak stall torque is 60.1 N.m across the 115...480 V three-phase range — that's the torque available for acceleration during short moves, limited by the drive's peak current capability. The motor has 5 poles, so the electrical frequency at 3000 rpm is 125 Hz.
Lifecycle and sourcing
The motor ships with the rotatable right-angled connector fitted; the holding brake is integrated and tested at the factory.
