Three-phase servo with holding brake — 1190 W at 6000 rpm
The SH31001P1AF4000 is a three-phase servo motor from the SH3 series, delivering 1190 W continuous output power at 400 V three-phase supply, with a nominal speed of 5000 rpm and a maximum of 6000 rpm at 480 V three-phase. It includes a holding brake rated at 9 N.m holding torque — this is the spec that determines whether the motor can hold a vertical load at rest without drifting when the drive is disabled. The absolute single-turn Hiperface DSL encoder provides position feedback without needing a home cycle on power-up, which saves commissioning time on multi-axis machines.
Speed-torque envelope and drive sizing
Nominal torque is 2.64 N.m at 230 V single-phase and 2.27 N.m at 400 V or 480 V three-phase — the torque drops slightly at higher line voltages because the motor reaches its rated speed earlier in the constant-torque region. Continuous stall torque is 2.94 N.m across the 115...480 V three-phase range, and peak stall torque reaches 9.6 N.m — the 3.3× overload margin handles acceleration and deceleration transients without oversizing the drive. Maximum continuous current Irms is 12.0 A, matching the 3s peak current rating — the drive's continuous current rating should be at least 12 A to avoid thermal overload on sustained high-speed runs.
Mounting interface and mechanical limits
The motor flange is 100 mm (3.9 in) with a 19 mm (0.7 in) shaft diameter and parallel key — this is the standard IEC mounting interface for frame size 100, so it bolts directly to matching gearboxes and linear actuators without an adapter plate. Overall length is 199.5 mm (7.9 in) with a centring collar depth of 3.5 mm — the collar registers the motor concentric to the mating flange, so the pilot diameter on the load side must match the collar depth to avoid misalignment. Maximum radial force Fr is 1930 N at 1000 rpm, derating to 1340 N at 3000 rpm — a belt-drive or overhung pulley load must stay within these limits or the bearing life drops below the motor's service interval. Maximum axial force Fa is 300 N — relevant for direct-coupled loads where thermal expansion or misalignment pushes axially against the shaft.
IP rating and environmental sealing
The shaft bushing without the shaft seal ring is only IP54 — if the application sees direct spray on the shaft exit, the optional shaft seal ring should be fitted to maintain the IP65 rating at the rotating interface. Cooling is natural convection (no external fan), so the motor relies on the mounting flange and ambient airflow for heat rejection — derate the continuous torque if the motor is enclosed in a non-ventilated cavity.
Electrical parameters for drive tuning
Stator resistance is 3.8 Ohm and stator inductance is 19 mH — these values go into the drive's motor model for current-loop auto-tuning; a mismatch here causes torque ripple at low speed. Torque constant is 0.84 N.m/A at 120 °C copper temperature, and back-EMF constant is 60 V/krpm at 20 °C — the drive uses these to calculate the torque command from current feedback and to set the velocity-loop feed-forward gain. Brake pull-in power is 12 W — the 24 VDC brake supply must be rated for at least this draw, and the drive's brake control output should switch the full 12 W without a separate relay.
The sizing reference is SH31001P — this is the base model identifier for the motor variant; the full order code SH31001P1AF4000 includes the brake, encoder type, and connector options.
