MH3 frame, 190 mm flange, sized for mid-range machine axes
The MH31901P01A2200 is the MH3 platform's mid-frame 7.5 in (190 mm) flange servo motor, a three-phase brushless design with natural-convection cooling and a smooth 38 mm shaft, intended for the duty envelope between the smaller MH2 frames and the larger MH4/MH5 machines.
Peak torque, peak current, and the 110 N.m transient envelope
Peak stall torque is 973.6 lbf.in (110 N.m) across 115 to 480 V three-phase, paired with an 89.61 A 3-second peak output current — that 110 N.m figure is roughly 6.7× the continuous torque, so the move profile is what sets the sizing question, not the steady-state load.
Hiperface feedback and IP65 sealing on the machine
Feedback is a single-turn SinCos Hiperface encoder on rotatable right-angled connectors, with a smooth 80 mm shaft and no holding brake — the brake-free configuration suits vertical axes that handle their own counterbalance or horizontal loads where the drive's regenerative braking is sufficient. Radial load capacity is sized for a typical pinion or belt drive: 2900 N at 1000 rpm tapering to 2600 N at 4000 rpm — the right-angle connector orientation lets the cable exit clear of the belt path on most machine layouts.
Drive pairing and electrical constants
Stator resistance 0.24 Ohm and inductance 5.08 mH, with a torque constant of 1.3 N.m/A at 248 °F (120 °C) winding temperature and a 5-pole rotor — the 1.3 N.m/A constant combined with the 23.2 A continuous stall current confirms the 30 N.m continuous stall figure, and the 120 °C reference lets the drive model the I²R losses accurately under load.
