40 mm flange, 8 mm shaft — fits the compact axis
The SH30402P17F2000 is a 40 mm flange-size servo motor from the Schneider SH3 family, 119.4 mm body length, with an 8 mm diameter shaft and a 3 mm parallel key. The shaft runs 25 mm long with a 2.5 mm centring collar depth — the mounting pattern is four 4.5 mm holes on a 30 mm centring collar, matching the international standard flange for this frame size. The rotatable right-angle connector lets the cable exit in any of four orientations, which simplifies routing in a crowded control cabinet or on a moving gantry.
Speed-torque envelope across supply voltages
This motor delivers 0.31 Nm nominal torque at 400 V or 480 V three-phase, with a nominal speed of 9000 rpm at those voltages. On single-phase 115 V or 230 V, nominal torque drops to 0.292 Nm and speed to 4000 rpm — the drive selection must match the supply available on site. Continuous power is 290 W, and peak stall torque reaches 1.5 Nm at 480 V three-phase. The continuous stall torque is 0.39 Nm across the three-phase voltage range, with a continuous stall current of 1.5 A. Maximum current Irms is 7.2 A, and the same figure applies as the 3-second peak output current.
Feedback and holding brake — what the encoder and brake ratings mean
The Absolute multiturn SinCos Hiperface encoder provides absolute position feedback over multiple shaft revolutions, with sine-cosine signals for high-resolution interpolation. This is the standard feedback type for closed-loop servo drives that need position retention after power cycle — no homing sequence required on restart. The holding brake delivers 0.4 Nm holding torque and is engaged when power is removed. This keeps the vertical load from dropping on a Z-axis or conveyor stop — the brake torque exceeds the nominal motor torque, so it holds the shaft against the rated load even if the drive loses power. Motor constants help the drive tune current loops: torque constant 0.26 Nm/A at 120 °C copper temperature, back EMF constant 18 V/krpm at 20 °C. Stator resistance is 11.6 Ohm and inductance 6.4 mH — these feed into the drive's auto-tuning routine for current regulator gains.
IP rating and cooling — where it runs sealed
The motor is rated IP65 with the shaft bushing and seal ring installed, per IEC 60034-5. Without the shaft seal ring, the shaft bushing alone is IP54. Cooling is natural convection — no external fan or liquid cooling. The continuous torque and power ratings assume free air circulation around the motor body; mounting it in a confined pocket or against a heat source will require derating.
