Motor ratings that decide the drive match
The SH32051P11A2100: This SH3-series servo motor is a three-phase synchronous machine — the drive it pairs with must be a three-phase servo drive, not a single-phase VFD. At 400 V three-phase supply it delivers 5500 W continuous power at 3000 rpm nominal speed; at 480 V three-phase the speed shifts to 3600 rpm with 5200 W output. The torque numbers tell the real story for sizing: 17.5 N.m continuous at 400 V three-phase, dropping to 13.8 N.m at 480 V three-phase. Peak stall torque hits 110 N.m across the 115-480 V three-phase range — that's the number for acceleration and emergency stop calculations, not the continuous figure.
Encoder and feedback — what the Hiperface means on site
The absolute single-turn SinCos Hiperface encoder gives position feedback at power-up without a homing cycle — critical for applications where the axis must know its position immediately after a power loss or emergency stop. Single-turn means it tracks one revolution; multi-turn applications need a different encoder option. The encoder signal is analog SinCos, not digital incremental — the drive's feedback card must support Hiperface protocol. Most modern servo drives from the same family handle this, but verify the drive's encoder interface before wiring.
Mounting and environment — fits the cabinet, survives the floor
IP65 on both the motor body and the shaft bushing per IEC 60034-5 means it handles washdown and dusty environments without a secondary cover. The straight connector and rotatable right-angled connector options let the cable exit in tight enclosures — choose the rotatable version when the motor sits against a panel wall. The international standard flange measures 205 mm (8.07 in) with a 180 mm centring collar and 14 mm mounting holes — this is a standard frame size that bolts to most servo gearboxes and machine frames without adapter plates. The 38 mm shaft with parallel key and 10 mm keyway is a common industrial interface.
Thermal and mechanical limits — don't oversize the cooling
Natural convection cooling means no fan — the motor relies on its surface area and the machine structure to shed heat. The 5500 W continuous rating assumes free airflow around the housing; mounting it in a sealed pocket or against a heat source derates the output. Copper winding temperature is rated to 130 °C hot. Maximum radial force at the shaft is 3730 N at 1000 rpm, dropping to 2580 N at 3000 rpm — belt-drive applications need to stay under these limits to avoid bearing damage. Axial force max is 740 N, so direct-drive or thrust-load applications must be checked against this ceiling.
