Motor dimensions and mounting — 12.6 in length, 205 mm flange
The SH32051P11A2200: Overall body length is 12.6 inches (321 mm) from the mounting face to the back of the housing — measure your panel depth before ordering. The motor flange measures 8.07 inches (205 mm) across, with a centring collar diameter of 7.09 inches (180 mm) that locates into the mating bore. Four mounting holes on a 0.6-inch (14 mm) diameter bolt circle hold it to the machine frame. Shaft diameter is 1.5 inches (38 mm) with a parallel keyway, key width 0.4 inch (10 mm), and shaft length 3.1 inches (80 mm). The centring collar depth is 0.2 inch (4 mm) — that shallow pilot means the motor face sits nearly flush against the mounting plate.
Power and torque across supply voltages
This 5-pole servo motor delivers different output depending on what voltage you feed it. On 400 V three-phase, nominal output is 5500 W continuous at 3000 rpm with 154.9 lbf·in (17.5 N·m) of torque. Bump it to 480 V three-phase and speed climbs to 3600 rpm but torque drops to 122.1 lbf·in (13.8 N·m), giving 5200 W. On single-phase 230 V, you get 4240 W at 1500 rpm with 239.0 lbf·in (27 N·m). The peak stall torque is 973.6 lbf·in (110 N·m) across the 115–480 V three-phase range — that's the short-duration muscle for acceleration. Continuous stall torque sits at 326.6 lbf·in (36.9 N·m) for three-phase supplies. The torque constant is 1.75 N·m/A at 248 °F (120 °C) copper temperature — that's the hot winding condition, not the cold-start number. Back EMF constant is 104 V/krpm at 68 °F (20 °C). Stator resistance is 0.3 ohm and inductance is 2.97 mH, which your drive's current loop tuning needs to handle.
Sealing and cooling — IP65/IP67, natural convection
The motor body carries IP65 per IEC 60034-5 on the motor and shaft bushing, with IP67 on the housing — meaning it handles washdown spray and temporary immersion. No fan on this one: cooling is natural convection, so the motor relies on the machine frame or ambient air movement to shed heat. The maximum copper temperature is 266 °F (130 °C), so if you're running it hard in a hot cabinet, derate the continuous torque or add forced airflow. The electrical connection is a rotatable right-angled connector — you can orient the cable exit in 90° increments to fit tight cable trays or panel entries. No holding brake fitted, so if you're mounting this on a vertical axis, plan for an external brake or a drive with a holding function.
Bearing loads and encoder feedback
Feedback comes from an absolute single-turn SinCos Hiperface encoder — gives position at power-up without a homing cycle, and the sine-cosine signals provide high-resolution interpolation for the drive. Single-turn means it tracks position within one revolution; if your application needs multi-turn absolute position over several shaft rotations, this encoder won't cover it without a battery-backed multi-turn unit.
