Torque and power delivery across the speed range
The MH31403P11F2200: Rated for 4750 W continuous output, this motor delivers 22.17 Nm nominal torque at 115 V three-phase supply, derating to 13.06 Nm at 400 V or 480 V three-phase. The peak stall torque reaches 75 Nm, while continuous stall torque holds at 24 Nm — figures that govern acceleration and overload capacity in the application. Nominal speed options span 750 rpm, 1750 rpm, and 3500 rpm depending on the drive supply voltage and phase configuration — the motor is wound for three-phase operation and the speed is set by the drive's output frequency and voltage. The integrated holding brake delivers 23 Nm holding torque, with a pull-in power of 19 W. This keeps the load locked at standstill without continuous current draw from the drive.
Encoder feedback and mechanical interface
A single-turn SinCos Hiperface encoder provides absolute position feedback within one revolution — no homing sequence needed on power-up for rotary axes that stay within a single turn. The encoder type is critical for drive compatibility; the Lexium 52 or 62 series drives listed in the spec table match this feedback interface. The motor mounts on an international standard flange with a 140 mm flange size and 130 mm centring collar diameter. The shaft is 24 mm diameter with a parallel key, 50 mm shaft length, and an 8 mm key width — dimensions that match standard coupling and pulley bores. IP65 protection means the motor body is sealed against dust ingress and low-pressure water jets — suitable for washdown environments but not for submersion. The rotatable right-angled connectors allow the cable exit to be oriented in the field, easing routing in tight cabinets.
Electrical parameters and thermal limits
Stator resistance measures 0.22 Ohm and inductance 3 mH, giving the drive's current loop a known load. The torque constant is 1.33 Nm/A at 120 °C copper temperature, and the back EMF constant is 85.9 V/krpm — these define the voltage-speed relationship and the current needed for a given torque. Maximum continuous stall current is 18 A, with a peak Irms of 62.32 A. The 10-pole motor uses natural convection cooling, so the continuous ratings assume free airflow around the housing — derate if mounted in a confined space or near heat sources.
