Three-phase winding, supply-dependent speed and torque
The SH30553P02A2100: This SH3 servo motor is wound for three-phase supply — the nominal speed and torque both shift with the input voltage. At 400 V three-phase it delivers 6000 rpm and 0.81 Nm continuous; at 115 V single-phase the same motor runs at 2000 rpm with 1.13 Nm. The drive must be configured for the actual supply voltage to get the rated performance. Continuous power is 680 W regardless of supply — that's the thermal limit the motor can sustain indefinitely. Peak stall torque reaches 3.5 Nm for short-duration acceleration or breakaway, but the continuous stall torque is 1.05 Nm at 1.7 A.
Feedback and mounting — what the drive needs to see
The encoder is an absolute multiturn SinCos Hiperface type — the drive must support Hiperface protocol to read position and commutation data. Not all servo drives accept this feedback; check the drive's encoder input compatibility before pairing. The motor has a smooth shaft (no keyway) with a 9 mm diameter and 20 mm shaft length. The flange is 55 mm square with a 40 mm centring collar and 2 mm collar depth — standard international flange dimensions that match most common mounting brackets.
Environmental sealing and cooling
IP65 rating on both the motor body and the shaft bushing means the motor is protected against dust ingress and low-pressure water jets from any direction. This makes it suitable for washdown areas in food processing, packaging, or machining environments where coolant spray is present. Cooling is by natural convection — no external fan or forced air required. The motor relies on its own surface area and the mounting flange to dissipate heat. In a confined enclosure or high-ambient-temperature setting, the continuous torque may need derating.
Active production — sourcing for new builds and spares
The electrical connection uses a rotatable right-angled connector, which allows the cable exit direction to be oriented after installation — useful when routing in tight cable trays or drag chains.
