Product details

1500 W continuous power — sizing the SH31003M12A1200 to the load

The SH31003M12A1200 delivers 1500 W continuous power, with nominal torque ranging from 69.04 lbf.in (7.8 N.m) at 115 V single-phase down to 59.83 lbf.in (6.76 N.m) at 480 V three-phase — the torque budget drops as line voltage rises, so size the load for the supply you actually have. Nominal speed varies with supply: 500 rpm at 115 V single-phase, 1000 rpm at 230 V single-phase, 2000 rpm at 400 V three-phase, and 2400 rpm at 480 V three-phase. Match the drive's output voltage and frequency to hit the target speed band. Peak stall torque is 250.5 lbf.in (28.3 N.m) across the 115–480 V three-phase range, with a continuous stall torque of 70.8 lbf.in (8 N.m) at 3.4 A continuous stall current. The 14.7 A maximum current (Irms) tells the drive what to budget for acceleration transients.

Encoder and feedback — absolute multiturn Hiperface

Fitted with an absolute multiturn SinCos Hiperface encoder — this gives position feedback over multiple shaft revolutions without a home cycle on power-up. The drive must support Hiperface protocol; check the drive's encoder interface before wiring. Back EMF constant is 148 V/krpm at 68 °F (20 °C), and the torque constant is 2.35 N.m/A at 248 °F (120 °C) — these numbers feed the drive's motor model for current-loop tuning and velocity estimation.

Enclosure, cooling, and mounting — IP65/IP67 with natural convection

IP65 on the motor body and shaft bushing, IP67 on the housing per IEC 60034-5 — this motor handles washdown in food-and-beverage or wet machining environments. No fan; natural convection cooling means the ambient temperature and duty cycle govern the thermal budget. Mounts on a 100 mm international standard flange with a 95 mm centring collar and 9.0 mm mounting holes. The shaft is 19 mm diameter with a parallel key, 40 mm shaft length, and 6 mm key width — standard interface for most gearboxes and pulleys. Electrical connection is via a straight connector — no right-angle or field-wireable option listed, so plan the cable exit path in the cabinet layout.

Sourced through independent distribution channels. No stock-holding claim; quoted per RFQ.

Frequently asked questions

What is the SH31003M12A1200's encoder type?

It uses an absolute multiturn SinCos Hiperface encoder, providing position feedback over multiple revolutions without a homing cycle.

Does the SH31003M12A1200 include a holding brake?

No, this variant is listed as 'without' holding brake. The application must provide external braking or rely on the drive's holding function.
