What this servo motor delivers on the line
The SH31403P01A2000 is a three-phase servo motor from the SH3 series, delivering 4.1 kW continuous power with a nominal speed of 3000 rpm at 400 V three-phase supply. At that voltage, nominal torque is 12.9 N·m (114.2 lbf·in), and peak stall torque reaches 90.2 N·m (798.3 lbf·in) across the 115–480 V three-phase range.
Encoder, feedback, and connector — what fits the cabinet
The motor carries an absolute single-turn SinCos Hiperface encoder, giving position feedback at power-up without a homing cycle — useful on multi-axis gantries where the controller needs to know where each axis sits after a power cycle. Electrical connection is via a rotatable right-angled connector, which lets the cable exit in the direction that suits the cabinet layout — no forced bend radius against the motor housing. The motor flange is 140 mm (5.5 in) with an international standard flange mounting and a centring collar diameter of 130 mm (5.1 in). The smooth shaft is 24 mm diameter, 50 mm length, so it accepts a standard keyless coupling or a clamp-on pulley.
Protection and cooling — where it runs without a fan
Cooling is by natural convection — no external fan, so the motor relies on its own surface area and the machine's airflow to shed heat. The IP degree of protection is IP54 at the shaft bushing without a shaft seal ring, and IP65 at the motor body and shaft bushing with the seal ring fitted, conforming to IEC 60034-5. That means it handles dust and splash in a washdown environment as long as the seal ring is in place. Maximum radial force Fr is 2420 N at 1000 rpm, dropping to 1670 N at 3000 rpm — the bearing load capacity follows the speed. Maximum axial force Fa is 300 N. These numbers govern the overhung load on the shaft when driving a belt or a direct-coupled load.
Lifecycle and sourcing — active, quoted to order
