Voltage-dependent performance — the supply decides the speed and torque
The SH31001M01A2000 is a three-phase servo motor, but its nominal speed and torque shift dramatically with the supply voltage. At 480 V three-phase it delivers 3000 rpm and 22.30 lbf·in (2.52 N·m); at 115 V single-phase that drops to 625 rpm and 24.8 lbf·in (2.8 N·m). The nominal output power follows the same pattern — 930 W at 480 V three-phase, 210 W at 115 V single-phase. The continuous power rating of 660 W is the thermal limit of the winding; the actual shaft power available depends on what voltage the drive puts on the terminals.
Encoder feedback and drive compatibility
The motor carries an absolute single-turn SinCos Hiperface encoder. That means the feedback protocol is Hiperface — the drive must support SinCos Hiperface to read position and speed. Single-turn gives absolute position within one revolution; after a power cycle the drive knows the shaft angle but not how many turns have passed. The rotatable right-angled connector lets the cable exit in any of four directions, which helps when the motor is shoehorned into a tight axis.
IP rating depends on the shaft seal fitted
The motor body is rated IP65 per IEC 60034-5, but the shaft bushing is IP54 without the optional shaft seal ring. If the application sees washdown or coolant spray, the shaft seal ring must be specified separately — the IP65 rating on the body doesn't extend through the shaft opening without it. Natural convection cooling means no fan to clog, but the thermal budget relies on free air movement around the flange.
