Motor specs that decide the drive match
The SH31002M02A2100: This SH3 frame servo delivers 1.1 kW continuous power with a nominal torque of 5.62 N.m at 400 V three-phase supply, spinning at 2000 rpm. The torque constant is 2.32 N.m/A measured at 120 °C copper temperature, so the drive current loop scales directly from this value. Peak stall torque hits 18.3 N.m across the 115–480 V three-phase range, giving the acceleration headroom for rapid indexing moves. Continuous stall torque is 5.8 N.m at 2.5 A — the motor holds position without overheating in a stalled condition.
Encoder and feedback — what the drive sees
The absolute multiturn SinCos Hiperface encoder reports position on power-up without a homing cycle. This saves one I/O point and a home-prox sensor on the machine, but the drive must support the Hiperface protocol — check the drive's encoder card compatibility before wiring. Back EMF constant is 146 V/krpm at 20 °C. At 2000 rpm the motor generates 292 V line-to-line, which stays under the DC bus voltage of a standard 400 V drive with margin for field-weakening operation.
Mounting and environment — IP65 and the flange
IP65 rating on both the motor body and the shaft bushing per IEC 60034-5 means this motor handles washdown without an additional cover. The 100 mm flange with a 95 mm centring collar and 9 mm mounting holes bolts directly to standard metric gearbox or machine frames. Natural convection cooling — no fan or external blower. The 130 °C copper hot-spot temperature limits the duty cycle in a stalled or low-speed condition; continuous stall at 2.5 A is the thermal ceiling for holding applications.
