5.5 kW continuous, 3000 rpm — torque and speed across supply voltages
The SH32051P12A1100 delivers 5.5 kW continuous output power at 400 V three-phase supply, with nominal speed reaching 3000 rpm on that same supply. On 480 V three-phase it still puts out 5.2 kW at 3600 rpm, so the speed ceiling shifts with the line voltage — a common reality in plants where the actual bus voltage varies. Continuous stall torque is 36.9 N·m across the 115...480 V three-phase range, and peak stall torque hits 110 N·m — that's the short-term muscle for accelerating a load or breaking through a jam without tripping the drive.
IP65 seals and natural convection — built for dusty, hot enclosures
IP65 on both the motor body and the shaft bushing per IEC 60034-5 means this motor is sealed against dust ingress and low-pressure water jets — it eats the dust and runs in a cement plant or grain-handling environment without needing a purge enclosure. Cooling is natural convection — no fan, no filter to clog. That simplifies maintenance in dirty atmospheres but means the thermal budget depends on the mounting surface and ambient air movement; the copper winding temperature is rated for 130 °C hot spot.
Absolute multiturn encoder — position hold through power cycles
The absolute multiturn SinCos Hiperface encoder tracks position across power cycles, so a homing sequence after every power-up is unnecessary. For a kiln feed or conveyor system that cycles daily, that saves a minute per restart and eliminates the risk of a missed home position. Back EMF constant is 104 V/krpm at 20 °C, and the torque constant is 1.75 N·m/A at 120 °C hot winding — these numbers let the drive correctly model the motor's voltage and current demand across the speed range.
