Motor ratings and what they mean for your axis
The SH30402P16F2100 delivers 290 W continuous power with a nominal torque of 0.31 N.m when fed from a 400 V or 480 V three-phase supply. That torque is available up to the rated speed of 9000 rpm — the full power band spans from stall to that ceiling, so the motor can run a direct-drive spindle or a low-ratio belt without needing a gearbox to reach line speed. Peak stall torque hits 1.5 N.m at 480 V three-phase — about 5× the continuous rating. That burst is what accelerates a high-inertia load through the first few revolutions or pushes through a momentary jam. The 7.2 A peak current and 7.2 A maximum Irms tell the drive what to budget for the current loop; the 6.4 mH stator inductance and 11.6 Ohm stator resistance set the electrical time constant the servo drive's tuning parameters need to handle.
Encoder feedback and mechanical fit
The absolute single-turn SinCos Hiperface encoder reports position on power-up — no homing sequence, no battery-backed multi-turn count. That saves a reference run after every power cycle, which matters on machines where the axis must hold its last commanded position through a power loss. The shaft is 8 mm diameter with a 25 mm length and a 3 mm parallel key. The 40 mm flange with a 30 mm centring collar and 2.5 mm collar depth bolts to standard IEC 40-frame gearboxes and mounting brackets. Four 4.5 mm mounting holes on the flange face — M4 or #8 bolts fit. The rotatable right-angled connector lets the cable exit point be oriented in 90° increments after the motor is bolted down — useful when the cable tray approach angle changes or when the motor sits in a corner of the cabinet with limited clearance.
Environmental sealing and cooling
The seal at the shaft exit is the vulnerable point; the IP65 bushing rating here covers it, so coolant mist won't wick into the bearing housing. Cooling is natural convection — no fan, no compressed air. The 290 W continuous rating assumes free air movement around the 119.4 mm body. If the motor is inside a cramped enclosure or near a heat source, the available torque derates; the thermal time constant is set by the copper winding temperature limit of 120 °C.
Sourcing and lifecycle status
No official successor or cross-reference is listed — the SH30402P16F2100 is the current variant for the 40 mm flange, 290 W, brake-equipped configuration. The sizing reference SH30402P groups the frame and winding family; confirm the encoder type and brake option match the BOM line before ordering.
