The SH30551P02F2200 is a 290 W three-phase servo motor from the SH3 series, fitted with a holding brake and an absolute multiturn SinCos Hiperface encoder. The 0.8 N.m holding torque keeps the load locked when power is removed — essential for vertical axes or any application where the load must not drift during a power loss or at standstill. Nominal torque is 0.5 N.m on single-phase supplies (115 V or 230 V), dropping to 0.35 N.m on three-phase 400 V or 480 V supplies. The continuous stall torque is 0.42 N.m across the full voltage range, so the motor delivers rated torque even at zero speed for holding or positioning tasks.
Speed range and power delivery across line voltages
Nominal speed depends on the supply: 2000 rpm at 115 V single phase, 4000 rpm at 230 V single phase, and 6000 rpm on either 400 V or 480 V three phase. Nominal output power also shifts — 100 W on 115 V, 210 W on 230 V, 400 W on 400 V, and 440 W on 480 V. The 290 W continuous power rating sits between these operating points, so the actual delivered power depends on the drive voltage and the duty cycle. Peak stall torque reaches 1.5 N.m on three-phase supplies (115...480 V), giving the axis a short-term overload capability for acceleration or overcoming friction during start-up. The maximum current Irms is 2.9 A, with the same 2.9 A peak output current for 3 seconds.
Encoder feedback and environmental sealing
The absolute multiturn SinCos Hiperface encoder provides position feedback without needing a home cycle after power-up — the multiturn count tracks absolute position over multiple shaft revolutions. This saves time on commissioning and eliminates the homing sequence on each power cycle. IP65 protection on the motor body and shaft bushing, with IP67 on the housing, means the motor withstands washdown environments and airborne particulates. Natural convection cooling keeps the design simple — no fan or external blower required, but the thermal limit (130 °C copper hot) must be respected in the duty cycle.
Mounting and connection details for panel integration
The motor uses an international standard flange with a 55 mm flange size and a 40 mm centring collar. The smooth shaft (9 mm diameter, 20 mm length) accepts a clamp-type coupling — no keyway, so the coupling must transmit torque through friction or a set-screw interface. Electrical connection is via a rotatable right-angled connector, which lets the cable exit in the direction that best fits the machine frame or cable track. Overall length is 159 mm (6.3 in), with a 2 mm centring collar depth.
