Speed-torque envelope across supply voltages
The SH31001M11A2000: This SH3 frame motor delivers 660 W continuous power, but the nominal speed and torque depend on the supply. At 480 V three-phase it spins 3000 rpm with 22.30 lbf.in (2.52 N.m) nominal torque; at 115 V single-phase the speed drops to 625 rpm and torque rises to 24.8 lbf.in (2.8 N.m). Peak stall torque is 85.0 lbf.in (9.6 N.m) across the 115–480 V three-phase range — useful for short-duration overloads during acceleration or load transients. Maximum mechanical speed is 6000 rpm, giving overspeed margin above the nominal 3000 rpm ceiling.
Encoder feedback and mounting constraints
The absolute single-turn SinCos Hiperface encoder provides position feedback without requiring a homing sequence on power-up — critical for applications where the axis position must be known immediately after a power cycle. This variant ships without a holding brake. For vertical-axis or gravity-loaded applications, an external brake or a motor with an integrated brake must be specified. The rotatable right-angled connector allows the cable exit to be oriented in four positions, easing cable routing in tight cabinets.
Cooling, sealing, and mechanical limits
Cooling is by natural convection — no fan, so the motor relies on free air movement. Ensure adequate clearance around the housing for heat dissipation. IP rating depends on the shaft bushing: IP54 without the shaft seal ring, IP65 with the seal ring fitted. For washdown environments, specify the IP65 configuration. Maximum radial force Fr derates with speed: 900 N at 1000 rpm, dropping to 530 N at 5000 rpm. Belt-driven loads must respect this curve to avoid bearing overload.
