Supply-voltage-dependent speed and torque — one motor, four operating points
The SH31001M12F2100: This SH3 frame servo motor delivers different nominal speeds depending on the supply: 625 rpm on 115 V single-phase, 1250 rpm on 230 V single-phase, 2500 rpm on 400 V three-phase, and 3000 rpm on 480 V three-phase. Nominal torque also shifts — 2.8 N.m at 115 V single-phase down to 2.52 N.m at 400 V or 480 V three-phase. The motor is wound for three-phase, so the single-phase figures assume a VFD with single-phase input and three-phase output. The continuous power rating is 660 W, but nominal output power ranges from 210 W (115 V single-phase) to 930 W (480 V three-phase) — the higher the line voltage, the more power you can extract before hitting the thermal limit.
Holding brake and encoder — what they mean for axis design
The integrated holding brake delivers 9 N.m holding torque — enough to hold a vertical load or keep the axis stationary when the drive is disabled, without an external mechanical lock or brake resistor. The absolute multiturn SinCos Hiperface encoder retains position through power cycles, so homing is not required on restart — critical for applications like gantries or rotary tables where lost position means a re-teach cycle.
IP65 and connector — washdown-ready with flexible cable exit
The motor body and shaft bushing are both rated IP65 per IEC 60034-5 — suitable for washdown environments in food-and-beverage or wet machining lines. The electrical connection is a rotatable right-angled connector, so the cable exit orientation can be adjusted on-site without opening the motor — useful when the motor is mounted in a tight space or the cable tray approach changes.
