Motor ratings and what they mean for your axis
The SH30702P0AA4000 is a Schneider Electric SH3 series servo motor rated for 1130 W continuous output power on a three-phase supply at 400 V or 480 V — on 230 V single-phase it delivers 610 W. Nominal torque is 2.1 Nm at 230 V, 1.8 Nm at 400 V or 480 V, with a peak stall torque of 7.6 Nm across the 115-480 V three-phase range. That peak figure governs acceleration and deceleration during short-duration moves; the continuous stall torque of 2.04 Nm sets the thermal limit for holding or low-speed positioning. Nominal speed varies with supply: 3000 rpm on 230 V single-phase, 6000 rpm on 400 V three-phase, 7200 rpm on 480 V three-phase. The motor is naturally convection-cooled (no fan), so duty cycle and ambient temperature directly affect the usable continuous torque — no forced airflow to extend the thermal envelope. This is a single-turn encoder — it reports position within one revolution but does not track multi-turn counts after power loss without a battery backup on the drive side.
Mechanical fit and mounting constraints
Mounts on a 70 mm (2.8 in) international standard flange with a 60 mm centring collar and 5.5 mm mounting holes. The smooth shaft measures 11 mm diameter by 23 mm length — no keyway, so the coupling or pulley must grip via a clamping or split-collar method. Overall length is 187 mm (7.4 in). Rated IP65 on the motor body per IEC 60034-5, with IP54 at the shaft bushing when the shaft seal ring is omitted. The rotatable right-angled connector (Quicklock type) allows the cable exit to be oriented in the field — useful when the motor is mounted in a tight enclosure corner. Maximum radial force Fr is 900 N at 1000 rpm; maximum axial force Fa is 160 N. These limits drop with speed — bearing life calculations should use the actual load and speed profile, not just the static maximum.
Electrical parameters for drive tuning and cable sizing
Stator resistance is 4.2 Ohm and stator inductance is 10.65 mH — these set the electrical time constant and influence the current-loop tuning gains on the servo drive. The torque constant is 0.7 Nm/A at 120 °C copper temperature; the back EMF constant is 48 V/krpm at 20 °C. Maximum continuous stall current is 2.9 A, with a 3-second peak current of 11.8 A.
