Frame and fit — 19.3 in long, 8.07 in flange, 1.5 in shaft
The SH32053P12A2100 is a three-phase servo motor with an overall length of 19.3 in (489 mm) and a motor flange size of 8.07 in (205 mm). The shaft diameter is 1.5 in (38 mm) with a parallel key and a shaft length of 3.1 in (80 mm). Mounting uses an international standard flange with a centring collar diameter of 7.09 in (180 mm) and a centring collar depth of 0.2 in (4 mm). The mounting holes are 0.6 in (14 mm) in diameter.
Speed and torque across supply voltages
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. Nominal torque also varies by supply: 751.4 lbf.in (84.9 N.m) at 115 V single phase, 658.5 lbf.in (74.4 N.m) at 230 V single phase, 448.7 lbf.in (50.7 N.m) at 400 V three phase, and 355.8 lbf.in (40.2 N.m) at 480 V three phase. Continuous power output follows the same pattern: 4450 W at 115 V single phase, 7790 W at 230 V single phase, 10620 W at 400 V three phase, and 10100 W at 480 V three phase. The motor is rated for 10600 W continuous power.
Torque capability — continuous and peak
Continuous stall torque is 835.5 lbf.in (94.4 N.m) across the 115...480 V three-phase range. Peak stall torque reaches 2920.7 lbf.in (330 N.m) over the same voltage range. The torque constant is 2.84 N.m/A at 248 °F (120 °C), and the back EMF constant is 172 V/krpm at 68 °F (20 °C). Maximum current Irms is 136.1 A, with a 3-second peak output current also at 136.1 A.
Encoder, cooling, and environmental protection
The motor uses an absolute multiturn SinCos Hiperface encoder for position feedback. There is no holding brake fitted. Cooling is by natural convection — no external fan or liquid cooling required. The IP degree of protection is IP65 for both the motor and the shaft bushing, conforming to IEC 60034-5, making it suitable for washdown or dusty environments. Electrical connection options include a straight connector or a rotatable right-angled connector, giving flexibility for cable routing in tight panels.
Electrical parameters and mechanical load limits
Stator resistance is 0.2 Ohm and stator inductance is 2.05 mH. The motor has 5 poles. The hot-spot copper temperature rating is 266 °F (130 °C).
