Speed profile across supply voltages
The SH31002M12F1100: This motor delivers 500 rpm on 115 V single-phase, 1000 rpm on 230 V single-phase, 2000 rpm on 400 V three-phase, and 2400 rpm on 480 V three-phase — the nominal speed shifts with the supply rail, so the drive parameter set must match the line voltage at the cabinet. Nominal torque holds at 5.62 N.m on 115 V single-phase, dropping slightly to 5.5 N.m on 230 V single-phase, and settling at 5.28 N.m on both 400 V and 480 V three-phase supplies.
Holding brake and mechanical interface
The integrated holding brake delivers 9 N.m of holding torque — enough to secure a vertical-axis load on a gantry or robot arm without a separate brake resistor or external holding circuit. Shaft is 19 mm diameter with a parallel key, 40 mm shaft length, and 6 mm key width — fits standard coupling and pulley bores for the 100 mm flange size.
Encoder and feedback loop
Absolute multiturn SinCos Hiperface encoder provides position feedback without a home cycle on power-up — the drive knows the rotor position immediately, which cuts commissioning time on multi-axis machines. Back EMF constant is 146 V/krpm at 20 °C — this sets the voltage ceiling for the drive bus; a 480 V supply gives headroom for the 2400 rpm top speed without saturating the drive output stage.
Environmental and thermal ratings
IP65 protection on both the motor body and shaft bushing per IEC 60034-5 — the motor withstands washdown and dust ingress, making it suitable for food-and-bev or wet machining lines without a secondary cover. Natural convection cooling with a copper hot-spot limit of 130 °C — no fan means no moving parts to fail, but the thermal time constant is longer; cycle duty must respect the continuous stall torque of 5.8 N.m across the 115–480 V range.
