Speed-torque envelope depends on your supply voltage
The SH32051P12A1000 delivers a different nominal torque and speed depending on whether the machine is wired for single-phase 115 V, single-phase 230 V, or three-phase 400/480 V. At 400 V three-phase, nominal speed is 3000 rpm with 154.9 lbf·in (17.5 N·m) of torque; on 115 V single-phase, speed drops to 750 rpm at 282.3 lbf·in (31.9 N·m). The buyer must match the load torque at the operating speed, not just the peak number. This is the thermal limit under continuous duty; the drive sizing must respect the supply configuration.
Peak-to-continuous torque ratio for transient overloads
Peak stall torque is 973.6 lbf·in (110 N·m) across the 115–480 V three-phase range, while continuous stall torque is 326.6 lbf·in (36.9 N·m). That is roughly a 3:1 peak-to-continuous ratio, telling the motion designer how much transient overload the motor can handle before the drive trips on I²t protection. The absolute multiturn SinCos Hiperface encoder provides high-resolution position feedback for precise velocity and position loops. Confirm the drive's encoder interface supports Hiperface protocol — not all servo drives accept this feedback type natively.
IP rating and connector options for installation
The motor carries IP54 at the shaft bushing without a shaft seal ring, and IP65 on the motor body and with the shaft seal ring installed, per IEC 60034-5. A commissioning engineer needs to know which variant is on the line before bolting it into a washdown zone — the shaft bushing seal is the wet-end barrier. Two electrical connection options are listed: a rotatable right-angled connector and a straight connector. The panel builder should pick the one that clears the cable duct or machine frame; the connector orientation affects the bend radius of the power and feedback cables. Mounting uses an international standard flange with an 8.07 in (205 mm) flange size and a 7.09 in (180 mm) centring collar diameter. The shaft is 1.5 in (38 mm) diameter with a parallel key, 3.1 in (80 mm) shaft length.
Active production — sourcing for BOM freeze or MRO
The motor is part of the SH3 series with sizing reference SH32051P.
