Motor sizing and torque delivery for the application
The MH31401P01F2200 delivers 2640 W continuous power from a three-phase supply, with a continuous stall torque of 10.3 N.m and a peak stall torque of 39.9 N.m — the peak figure governs short-duration acceleration or emergency stops, while the continuous stall torque sets the thermal limit for holding or low-speed positioning. The torque constant of 1.2 N.m/A at 120 °C copper hot means the drive must supply 8.58 A continuous stall current to hold the rated torque; the maximum current Irms of 29.8 A supports the 39.9 N.m peak torque for short overloads.
Encoder feedback and brake integration for vertical-axis safety
The single-turn SinCos Hiperface encoder provides absolute position within one revolution — no homing cycle needed after power-up for rotary tables or single-turn applications, but multi-turn position tracking requires a different encoder option. The integrated holding brake delivers 18 N.m holding torque and consumes 18 W pull-in power — the brake is sized to hold the load at standstill, not to decelerate it; the drive's dynamic braking resistor handles the kinetic energy during a stop. Back EMF constant of 77.41 V/krpm means at 4000 rpm the motor generates 310 V line-to-line — the drive's DC bus voltage must exceed this peak to maintain current control; a 480 VAC supply (680 VDC bus) provides sufficient headroom.
Mechanical fit and environmental sealing for the installation
The 140 mm flange (5.5 in) with a 130 mm centring collar and 0.4 in mounting holes matches the standard IEC frame size — the smooth shaft (24 mm diameter, 50 mm shaft length) accepts a keyless coupling or clamp-on pulley; the 0.1 in centring collar depth ensures concentric alignment to the load. The rotatable right-angled connectors allow the cable exit to be oriented in 90° increments after mounting — useful when the motor sits in a tight corner of the machine frame and the cable must route along the wall rather than straight out.
Radial load limits and cooling constraints for belt-driven loads
Maximum radial force Fr is 1930 N at 1000 rpm, derating to 1530 N at 2000 rpm and 1340 N at 3000 rpm — a belt drive or overhung pulley must be sized so the resultant belt tension stays below the speed-dependent limit; exceeding it shortens bearing life or causes shaft fatigue. Natural convection cooling means the motor relies on surface radiation and airflow from the driven load's motion — no external fan; continuous torque must be derated at low speeds where the self-cooling effect is minimal, especially below 500 rpm.
The sizing reference MH31401P anchors the motor's electromagnetic design; the full order code specifies the smooth shaft, brake, single-turn Hiperface encoder, and IP65 rating — any deviation in shaft keyway, encoder type, or brake voltage requires a different suffix.
