Motor ratings and supply voltage dependency
The SH32051P02A1000 is a three-phase servo motor whose nominal output power and torque shift with the supply voltage. At 400 V three-phase it delivers 5500 W continuous and 17.5 Nm nominal torque; at 480 V three-phase the continuous power is 5200 W with 13.8 Nm nominal torque. On single-phase 230 V the numbers drop to 4240 W and 27 Nm, and on 115 V single-phase to 2510 W and 31.9 Nm. The continuous stall torque is rated at 36.9 Nm across the 115–480 V three-phase range, with a continuous stall current of 21 A. Peak stall torque reaches 110 Nm at 87.2 A peak current (3 s rating). These figures anchor the motor's capability for high-torque acceleration and deceleration phases in cyclic duty.
Encoder and feedback — absolute multitrack position
The motor carries an absolute multiturn SinCos Hiperface encoder. This is a digital-plus-analog feedback interface that reports absolute position over multiple shaft revolutions without needing a battery-backed counter or a homing cycle on power-up. The SinCos analog tracks provide high-resolution velocity and commutation signals directly to the drive. For a commissioning engineer: the Hiperface protocol requires the drive's encoder input to support the specific data rate and voltage levels — confirm the drive's feedback card is listed for Hiperface before wiring. The straight connector exit means the cable exits axially; plan the cable routing and bend radius accordingly.
Mechanical interface and mounting
The motor mounts via an international standard flange with a 205 mm flange size and a 180 mm centring collar that locates the motor concentric to the driven load. Four mounting holes on a 14 mm diameter bolt circle secure the motor to the machine frame. The centring collar depth is 4 mm. The shaft is smooth, 38 mm diameter with an 80 mm shaft length. No keyway is specified — the coupling or pulley must clamp onto the smooth diameter. The maximum radial force at 1000 rpm is 3730 N, dropping to 2580 N at 3000 rpm. Maximum axial force is 740 N. These limits govern the overhung load from a belt drive or the thrust from a lead-screw coupling. The motor has no holding brake. For vertical-axis or safety-hold applications, the drive must provide a dynamic-braking resistor or an external mechanical brake must be coupled to the load side.
Protection and cooling
The IP degree of protection is IP54 at the shaft bushing without the shaft seal ring, and IP65 for the motor body and with the shaft seal ring installed — both per IEC 60034-5. The IP65 rating makes the motor suitable for washdown environments where water jets are directed at the housing, provided the seal ring is fitted. Cooling is by natural convection. No external fan or liquid cooling circuit is required, but the motor's continuous torque and power ratings assume free airflow around the housing. Enclosed or poorly ventilated mounting will require derating.
Electrical parameters and thermal limits
Stator resistance is 0.3 Ohm and stator inductance is 2.97 mH. The back EMF constant is 104 V/krpm at 20 °C. The torque constant is 1.75 Nm/A at 120 °C. The hot-spot temperature limit is 130 °C on the copper windings.
