The SH32052P12A1000: This is a three-phase servo motor from the SH3 series, rated for 7900 W continuous power. The nominal speed depends on the supply: 500 rpm at 115 V single-phase, 1000 rpm at 230 V single-phase, 2000 rpm at 400 V three-phase, and 2400 rpm at 480 V three-phase. That means the same motor covers a wide speed range depending on the drive and line voltage you feed it — useful if you're standardising on one frame size across multiple machine variants. Nominal torque follows the same pattern: 545.2 lbf.in (61.6 N.m) at 115 V single-phase, dropping to 251.4 lbf.in (28.4 N.m) at 480 V three-phase. The peak stall torque is 1947.2 lbf.in (220 N.m) across the 115...480 V three-phase range — that's the short-term overload capability for acceleration or emergency stops. Continuous stall torque is 574.4 lbf.in (64.9 N.m) under the same three-phase supply. The absolute multiturn SinCos Hiperface encoder gives position feedback without a home cycle after power loss — critical for applications like pick-and-place or gantry axes where the machine must know its position immediately on restart. The encoder type also dictates which servo drive models are compatible; most drives with Hiperface support will accept this motor.
IP65 protection and mounting dimensions
The motor carries IP54 on the shaft bushing without the seal ring, and IP65 on the motor body and shaft bushing when the seal ring is fitted. The IP65 rating conforms to IEC 60034-5. Overall length is 15.9 in (405 mm). The shaft diameter is 1.5 in (38 mm) with a parallel key, shaft length 3.1 in (80 mm), key width 0.4 in (10 mm). The motor flange size is 8.07 in (205 mm) with a centring collar diameter of 7.09 in (180 mm) and centring collar depth 0.2 in (4 mm). Mounting holes are 0.6 in (14 mm) diameter on an international standard flange. These dimensions let you check the bolt pattern and shaft coupling fit against your existing machine frame without pulling the old motor first.
