At single-phase supply, the speed drops to 750 rpm (115 V) or 1500 rpm (230 V), with torque rising to 30.2 N·m and 26.3 N·m respectively — the motor is wound for high torque at low voltage, not just high-speed three-phase operation. Continuous power at 400 V three-phase is 4040 W, with the peak stall torque reaching 131.9 N·m across the 115–480 V three-phase range — that short-term overload capability handles acceleration and emergency stops without oversizing the drive. ## Feedback and environmental sealing — drive compatibility and washdown fit The absolute multiturn SinCos Hiperface encoder means the motor retains position on power loss without a battery backup — the drive must support Hiperface protocol; common Lexium and third-party servo drives with Hiperface input will pair directly. No homing sequence needed after a power cycle. IP54 on the shaft bushing without the seal ring, IP65 on the motor body and with the shaft seal ring installed. For washdown or dust-prone lines, specify the shaft seal ring — without it, the bushing is splash-resistant only. The rotatable right-angled connector lets the cable exit orient to the panel gland plate without a separate junction box. ## Thermal and mechanical limits — natural convection, shaft loading, and mounting Natural convection cooling means no fan noise or filter maintenance, but the motor relies on the mounting flange and ambient air for heat rejection — derate continuous torque if the panel ambient exceeds 40 °C or if the flange is on a non-metallic surface. The 140 mm flange with 130 mm centring collar and 11 mm mounting holes is the standard IEC B5 pattern; the 24 mm smooth shaft accepts a keyless clamp coupling or collet-style hub. Maximum radial force Fr is 2660 N at 1000 rpm, dropping to 1840 N at 3000 rpm — belt-driven loads must stay within this envelope or the bearing life shortens. Maximum axial force Fa is 300 N, typical for direct-coupled loads; thrust loads from helical gears or lead screws need a separate thrust bearing. ## Electrical parameters for drive sizing — resistance, inductance, and current Stator resistance is 0.28 Ω and inductance is 2.035 mH — the electrical time constant is about 7.3 ms, which sets the current-loop bandwidth ceiling for the servo drive. Continuous stall current is 21.3 A, with a 3-second peak of 95.6 A — the drive must supply that peak current for acceleration without tripping its own I²t limit. The torque constant is 1.57 N·m/A at 120 °C copper temperature, so the continuous stall torque of 33.4 N·m aligns with the 21.3 A continuous current. Back EMF constant is 104 V/krpm at 20 °C — at 3000 rpm the generated voltage is 312 V line-to-line, which stays within the 400 V DC bus headroom of a standard drive. The 5-pole motor has a lower cogging torque ripple than a 4-pole design, which matters for smooth velocity control at low speeds. Lifecycle stage is current — Schneider continues to manufacture this SH3 frame motor; no end-of-life notice or last-time-buy window is open. The sizing reference SH31404P identifies the frame and winding variant for cross-referencing in Schneider's selection tools.","metaTitle":"Schneider Electric SH31404P02A2000 Servo Motor, 4040 W","metaDescription":"Schneider Electric SH31404P02A2000 servo motor, 4040 W continuous at 400 V three-phase, 3000 rpm nominal, 140 mm flange, absolute multiturn SinCos Hiperface","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Servo Motors with Brake"],"specifications":{"Phase":"Three phase","title":"SH31404P02A2000","Length":"15.06 in (382.5 mm)","Inertia":"0.0 kg.cm² of brake 23.7 kg.cm² of motor","Category":"US1PC5218359","Shaft end":"Smooth shaft","description":"SH3 servomotor, 140mm, 4 stacks, smooth Shaft, SinCos Multiturn 128, no Brake, angular, IP54/65","Encoder type":"Absolute multiturn SinCos Hiperface","Shaft length":"2.0 in (50 mm)","Holding brake":"Without","Nominal speed":"750 rpm 115 V single phase 1500 rpm 230 V single phase 3000 rpm 400 V three phase 3600 rpm 480 V three phase","Rotor inertia":"23.7 kg.cm²","Nominal torque":"267.3 lbf.in (30.2 N.m) 115 V single phase 232.8 lbf.in (26.3 N.m) 230 V single phase 114.2 lbf.in (12.9 N.m) 400 V three phase 98.2 lbf.in (11.1 N.m) 480 V three phase","Shaft diameter":"0.9 in (24 mm)","Torque constant":"1.57 N.m/A 248 °F (120 °C)","Type of cooling":"Natural convection","lifecycle_stage":"current","Continuous power":"4040 W","Mounting Support":"International standard flange","Sizing reference":"SH31404P","Back emf constant":"104 V/krpm 68 °F (20 °C)","Device short name":"SH3","Motor flange size":"5.5 in (140 mm)","Peak stall torque":"1167.4 lbf.in (131.9 N.m) 115...480 V three phase","Stator inductance":"2.035 mH","Stator resistance":"0.28 Ohm","Maximum current Irms":"95.6 A","Nominal output power":"2370 W 115 V single phase 4130 W 230 V single phase 4040 W 400 V three phase 4190 W 480 V three phase","Centring collar depth":"0.1 in (3.5 mm)","Electrical Connection":"Rotatable right angled connector","Electrical connection":"rotatable right angled connector","Nbr. of units in pkg.":"1","Number of motor poles":"5.0","Maximum axial force Fa":"300 N","Output current 3s peak":"95.6 A","Temperature copper hot":"266 °F (130 °C)","Continuous stall torque":"295.6 lbf.in (33.4 N.m) 115...480 V three phase","IP degree of protection":"IP54 shaft bushing without shaft seal ring: conforming to IEC 60034-5 IP65 motor: conforming to IEC 60034-5 IP65 shaft bushing: conforming to IEC 60034-5","Maximum radial force Fr":"2660 N 1000 rpm 2110 N 2000 rpm 1840 N 3000 rpm","Mounting holes diameter":"0.4 in (11 mm)","Centring collar diameter":"5.1 in (130 mm)","Continuous stall current":"21.3 A","Maximum mechanical speed":"4000 rpm","Network number of phases":"3","Number of mounting holes":"4","Product or Component Type":"Servo motor","Speed feedback resolution":"128 periods","[Us] rated supply voltage":"115...480 V","Circle diameter of the mounting holes":"6.5 in (165 mm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/f131210183157c2eb2e63c79321b0482.pdf","sourceUrl":"https://www.se.com/in/en/product/SH31404P02A2000/sh3-servomotor-140mm-4-stacks-smooth-shaft-sincos-multiturn-128-no-brake-angular-ip54-65/"},"ai":{"faq":[{"question":"What encoder type does SH31404P02A2000 use?","answer":"It uses an absolute multiturn SinCos Hiperface encoder.
