Motor ratings across supply voltages — the speed-torque profile that matters for your drive pairing
The SH31402P02A2200: This SH3 frame motor delivers 3.9 kW continuous power at 400 V three-phase, with a nominal speed of 3000 rpm and nominal torque of 12.3 N.m. At 480 V three-phase the nominal speed rises to 3600 rpm with torque dropping to 9.7 N.m, while the continuous power stays near 3660 W — the torque constant of 1.47 N.m/A at 120 °C sets the current-to-torque relationship for the drive tuning. Peak stall torque reaches 60.1 N.m across the 115–480 V three-phase range, with continuous stall torque at 19.5 N.m and a continuous stall current of 13.2 A. The 44.1 A peak current (3 s) defines the drive's short-term overload capability — the mating drive must support this peak for acceleration and deceleration transients.
Mechanical integration — flange, shaft, and sealing for washdown environments
The motor uses a 140 mm international standard flange (5.5 in) with a 130 mm centring collar and 3.5 mm collar depth — this matches the standard IEC mounting pattern for this frame size. Four mounting holes at 11 mm diameter on the flange face secure the motor to the machine frame. Shaft is a smooth 24 mm diameter × 50 mm length, without keyway — the smooth shaft suits direct coupling via a clamping-type shaft collar or a zero-backlash coupling with a split clamping hub. Maximum radial force at the shaft centre is 2240 N at 1000 rpm, derating to 1550 N at 3000 rpm; maximum axial force is 300 N. IP65 rated on the motor body and shaft bushing per IEC 60034-5, with the housing rated IP67 — the motor withstands washdown spray and temporary immersion, suitable for food processing, packaging, and other wet-area servo axes. The rotatable right-angled connector lets the cable exit orient to the machine frame, simplifying cable routing in tight enclosures.
Feedback and electrical interface — absolute encoder with Hiperface protocol
The absolute multiturn SinCos Hiperface encoder provides position feedback without a home cycle on power-up — the multiturn count tracks absolute position over multiple shaft revolutions, eliminating the need for a reference run after a power loss. The SinCos analog track gives high-resolution velocity feedback for the servo drive's current loop. Stator resistance is 0.6 Ω per phase with a stator inductance of 3.855 mH — these values set the electrical time constant and influence the drive's current regulator tuning. The back EMF constant is 101 V/krpm at 20 °C, which determines the maximum achievable speed at a given DC bus voltage. Cooling is by natural convection — no external fan or forced air required. The motor relies on its own surface area and the machine frame for heat dissipation; mounting on a thermally conductive surface (steel or aluminium machine base) improves the continuous torque capability in high-duty-cycle applications.
The motor ships as a single unit with the rotatable connector pre-fitted. No brake is fitted — this variant is for applications where the load holds position through the drive's holding torque or an external mechanical brake.
