Motor ratings that govern the drive match
The SH32051P12A2200 is a three-phase synchronous servo motor delivering 5500 W continuous power at 400 V three-phase input, with a nominal speed of 3000 rpm and nominal torque of 17.5 N.m under the same supply condition. Peak stall torque reaches 110 N.m across the 115...480 V three-phase range, while continuous stall torque is rated at 36.9 N.m — the margin between these figures defines the acceleration headroom for high-dynamic positioning moves. Maximum continuous current is 87.2 A, matching the 3-second peak current rating; the drive must be sized to supply this peak without entering current-limit foldback during acceleration transients.
Encoder and feedback — absolute position without homing
Fitted with an absolute multiturn SinCos Hiperface encoder, this motor reports shaft position over multiple revolutions without requiring a homing sequence on power-up — a direct time saving on multi-axis machines where each axis would otherwise need to find its reference mark. The Hiperface protocol carries both position and temperature data over a single cable pair, reducing the feedback cable count compared to incremental encoder systems that need separate limit-switch wiring.
Environmental sealing and cooling — no fan, no filter
Motor body and shaft bushing are IP65 per IEC 60034-5, with the housing rated IP67 — the motor withstands washdown and airborne particulates without an external shroud, suitable for food-processing or machining-centre coolant exposure. Cooling is by natural convection only; there is no integral fan, so the motor relies on the machine structure or ambient airflow for heat rejection. The thermal limit is set by the copper winding temperature of 130 °C, with stator resistance of 0.3 Ohm and inductance of 2.97 mH defining the I²R loss profile.
Mechanical interface — flange, shaft, and connector
Mounting uses an international standard flange with a 205 mm flange size and 180 mm centring collar diameter, secured through 14 mm mounting holes — a common fit for frame-size equivalent servo motors in European machine-tool practice. The shaft is 38 mm diameter with a 10 mm parallel keyway, 80 mm shaft length, and 4 mm centring collar depth — the keyed interface transmits the 31.9 N.m peak torque without slipping under reversal. Electrical connection is via a rotatable right-angled connector, allowing the cable exit to be oriented in four positions around the motor housing — useful when the motor is mounted in a tight enclosure corner where a straight connector would foul the panel wall.
