Product details

Active production — 290 W SH3 frame with Hiperface feedback

The SH30551P11A2100: Nominal speed depends on the supply voltage: 2000 rpm on 115 V single phase, 4000 rpm on 230 V single phase, and 6000 rpm on 400 V or 480 V three phase. The continuous stall torque is 0.42 Nm across the 115–480 V three-phase range, with a peak stall torque of 1.5 Nm.

Encoder, IP rating, and mechanical interface

Feedback is an absolute single-turn SinCos Hiperface encoder — this gives position at power-up without a homing cycle, which matters on multi-axis lines where the controller expects a known rotor angle on enable. The motor carries an IP65 rating on both the housing and the shaft bushing per IEC 60034-5, so it handles washdown and airborne particulates common in packaging and food-grade cells. Mounting uses an international standard flange with a 55 mm square face and a 40 mm centring collar. The shaft is 9 mm diameter with a parallel key, 20 mm length. A rotatable right-angled connector exits the motor body — useful when cable routing has to clear adjacent axis hardware.

Thermal limits and force ratings

Cooling is natural convection — no external fan, so the continuous torque assumes free air movement around the flange. The torque constant is 0.58 Nm/A at 120 °C copper temperature; the back EMF constant is 40 V/krpm at 20 °C. Stator resistance is 41.8 Ω and inductance is 37.13 mH, which sets the electrical time constant the drive's current loop must handle. Maximum radial force at the shaft is 340 N at 1000 rpm, derating to 170 N at 8000 rpm. Maximum axial force is 40 N. These limits govern direct-coupling decisions — a belt drive or overhung load that exceeds the radial force at the operating speed will shorten bearing life.

Frequently asked questions

What is SH30551P11A2100's listed phase and speed range?

The motor is wound for three-phase operation. Nominal speed reaches 6000 rpm on 400 V or 480 V three-phase supply; at 230 V single phase it runs 4000 rpm, and at 115 V single phase it runs 2000 rpm.

What encoder feedback does this motor use?

It uses an absolute single-turn SinCos Hiperface encoder. This provides absolute position within one revolution at power-up, eliminating the need for a homing sequence on each enable cycle.

What is the continuous and peak torque rating?

Continuous stall torque is 0.42 Nm across the 115–480 V three-phase range. Peak stall torque is 1.5 Nm at 115–480 V three phase.
