What this servo motor delivers for the line
The MH31003P11F2200 is a three-phase servo motor from the MH3 series, delivering 3270 W continuous power and 8.45 N.m nominal torque at 1000 rpm. That torque rating is the continuous-duty ceiling — the motor holds that output indefinitely under natural convection cooling, no forced air required. The holding brake is integrated, rated at 9 N.m holding torque and 18 W pull-in power. This is the spec to check for vertical-axis loads or any application where the motor must hold position with power off — the brake engages when the drive removes the holding current. Encoder feedback is a single-turn SinCos Hiperface type, which gives absolute position within one revolution. For multi-turn applications (e.g., ball-screw axes that travel more than one motor revolution), the drive must handle the single-turn limitation or a multi-turn encoder variant should be selected.
Torque and overload — what the numbers mean for sizing
Nominal torque is 8.45 N.m at 1000 rpm, but the motor can deliver 27 N.m peak stall torque — about 3.2× the continuous rating — for short-duration acceleration or peak loads. The peak figure holds across the full 115–480 V three-phase input range, so the drive bus voltage doesn't limit the burst capability. The torque constant is 1.17 N.m/A at 120 °C copper temperature — this is the hot-winding figure, not the cold-start value. Use it for thermal sizing of the drive's continuous current rating; the continuous stall current is 7.69 A, and the maximum RMS current is 26.71 A.
Physical fit and environmental sealing
The motor flange is 100 mm (3.9 in) with a 95 mm centring collar and 9 mm mounting holes — standard IEC metric flange pattern. Overall length is 234.3 mm (9.2 in) from the mounting face to the rear of the housing, not including the connector protrusion. The shaft is 19 mm diameter with a parallel key, 40 mm shaft length, and 6 mm key width. This is a standard keyed shaft — no special coupling required for most servo-rated shaft couplings. IP65 rating means the motor body is protected against dust ingress and low-pressure water jets from any direction. This suits washdown environments (food processing, packaging lines) but not full-pressure hose-down or submersion — the rotatable right-angled connectors must be properly seated to maintain the seal.
Electrical parameters for drive matching
Stator resistance is 1.08 Ω and stator inductance is 5.23 mH — these are the winding parameters the drive's autotune routine uses to set current loops. If the drive does not have an autotune for this specific motor model, enter these values manually from the motor nameplate or datasheet. Back EMF constant is 77.95 V/krpm. At 1000 rpm, the motor generates about 78 V line-to-line back EMF — the drive's DC bus must stay above this voltage plus the IR drop to maintain current control. For a 400 V bus, this is well within margin. The motor has 10 poles, which gives a nominal electrical frequency of about 83 Hz at 1000 rpm. The drive's carrier frequency and current-loop bandwidth should be set accordingly — standard servo drives handle this without issue.
