Speed-torque envelope across supply configurations
The SH31403P02A2200: This SH3 servo motor delivers a nominal torque of 24.7 N·m at 400 V three-phase, derating to 12.9 N·m at the same supply and 9.1 N·m at 480 V three-phase. On single-phase supplies, nominal torque drops further — 21.2 N·m at 230 V and 9.1 N·m at 115 V — so the application's available supply voltage directly sets the usable torque. Nominal speed shifts with the supply: 3000 rpm on 400 V three-phase, 3600 rpm on 480 V three-phase, and 750 rpm or 1500 rpm on 115 V or 230 V single-phase respectively. The maximum mechanical speed ceiling is 4000 rpm regardless of supply. Peak stall torque reaches 90.2 N·m across the 115–480 V three-phase range, while continuous stall torque is 27.8 N·m at 17.6 A continuous stall current. This 3.2× peak-to-continuous ratio suits applications requiring short high-torque bursts for acceleration or overcoming static friction.
Encoder feedback and electrical interface
The absolute multiturn SinCos Hiperface encoder provides position feedback without a battery-backed counter — useful for applications that must retain axis position through power cycles. The rotatable right-angled connector allows cable exit orientation adjustment during installation. Stator resistance is 0.4 Ω and inductance is 7.72 mH — these values feed into the servo drive's auto-tuning routine for current loop gains. The torque constant is 1.58 N·m/A at 120 °C copper temperature, and the back EMF constant is 105 V/krpm at 20 °C, which sets the voltage margin at high speed.
Mechanical fit and environmental sealing
The motor flange is 140 mm (5.5 in) with a 130 mm centring collar and 11 mm mounting holes on the international standard flange pattern. The smooth shaft is 24 mm diameter with a 50 mm shaft length — no keyway, so the coupling must clamp onto the shaft without a key. IP65 rating on the motor body and shaft bushing, IP67 on the housing — both per IEC 60034-5. This allows washdown exposure but not submersion; the shaft seal is the wet-end barrier. Cooling is by natural convection only — no external fan, so the motor relies on its own surface area and mounting plate for heat dissipation. Maximum axial force is 300 N; radial force limits are 2420 N at 1000 rpm, derating to 1670 N at 3000 rpm. These bearing load limits govern direct-drive or belt-drive applications — overshoot them and bearing life drops sharply.
Sourcing and lifecycle status
No official successor or cross-reference is recorded — this is the active variant in the SH3 family. The sizing reference SH31403P groups this motor with others sharing the same frame size and winding family.
