Motor frame and feedback — what the flange and encoder tell you
The MH30703P12A2200: The 70 mm flange (2.8 in) with a 60 mm centring collar and 5.5 mm mounting holes on a 4-hole pattern indexes the motor to the machine frame — the 2.5 mm centring collar depth sets the pilot engagement, so the face-mount register is the alignment datum, not the bolt circle. The multiturn SinCos Hiperface encoder delivers absolute position over multiple shaft revolutions without a battery-backed count — the sine-cosine analog tracks give the drive fine interpolated position at standstill, so the servo loop holds the micron at zero speed without dither.
Torque and speed envelope — what the drive voltage does to the numbers
Nominal torque at the motor shaft depends on the drive supply: 3.18 N·m at 115 V three-phase, 2.96 N·m at 230 V single-phase, 2.53 N·m at 400 V three-phase, and 2.26 N·m at 480 V three-phase — the torque constant of 0.87 N·m/A at 120 °C copper temp sets the current-to-torque ratio, and the 12.57 A maximum Irms defines the peak stall torque of 10.2 N·m across the 115–480 V range. Nominal speed likewise shifts with drive voltage: 1250 rpm at 115 V single-phase, 2500 rpm at 230 V single-phase, 5000 rpm at 400 V three-phase, and 6500 rpm at 480 V three-phase — the back EMF constant of 55 V/krpm governs the speed ceiling for a given DC bus voltage, so the 8000 rpm maximum mechanical speed is only reachable with sufficient bus headroom.
Thermal and mechanical limits — continuous duty and radial load
Maximum radial force at the shaft nose drops from 730 N at 1000 rpm to 400 N at 6000 rpm — the 14 mm shaft with a parallel key and 30 mm shaft length drives the belt or coupling load limit; a belt tension that exceeds 400 N at 6000 rpm shortens bearing life.
Sourcing and lifecycle — active production, quoted per BOM
No official successor or cross-reference — this is the current buildable variant in the MH3 series.
