Motor ratings that set the torque-speed envelope
The MH30703P16A2200 is a three-phase servo motor from the MH3 series, delivering a continuous output power of 1.54 kW at 480 V three-phase input. Its nominal speed sits at 5000 rpm, with a maximum mechanical speed of 8000 rpm — the headroom matters for rapid positioning moves where the drive overshoots the rated speed temporarily. Nominal torque is 3.18 Nm at 115 V three-phase, dropping to 2.26 Nm at 480 V three-phase as the voltage-dependent current limit tightens. Continuous stall torque is 3.4 Nm across the 115...480 V range, with a peak stall torque of 10.2 Nm — the 3x overload margin handles acceleration and deceleration without oversizing the motor frame.
Encoder feedback and electrical interface
The motor carries a Single-turn SinCos Hiperface encoder — an analog sinusoidal feedback type that gives the drive high-resolution position and speed data without a separate commutation track. It mates directly with Schneider LXM52 and LXM62 drive families, which decode the SinCos signals for field-oriented control. Electrical connection uses rotatable right-angled connectors, which let the cable exit direction be adjusted after mounting — useful when the motor sits in a tight cabinet corner where a fixed connector would force a cable bend radius violation.
Mechanical fit: flange, shaft, and cooling
The motor flange is 70 mm (IEC standard), with a 60 mm centring collar and 2.5 mm depth, four mounting holes at 5.5 mm diameter. The shaft is 14 mm diameter with a parallel key (5 mm key width) and 30 mm shaft length — no second shaft end, no holding brake. This is a bare-shaft motor for direct coupling to a load via a flexible jaw or bellows coupling. Cooling is by natural convection — no fan, so the motor relies on its own surface area and the machine frame to dissipate heat. The IP65 rating means the housing is dust-tight and protected against water jets, suitable for washdown environments but not submersion. Maximum radial force at the shaft nose is 730 N at 1000 rpm, derating to 400 N at 6000 rpm — the bearing life calculation should use the actual speed profile.
Electrical parameters for drive tuning
Stator resistance is 2.65 Ohm and stator inductance is 8.64 mH — these values go into the drive's auto-tuning routine for current-loop gains. Torque constant is 0.87 Nm/A at 120 °C copper temperature, and back EMF constant is 55 V/krpm. The 10-pole motor design gives a lower cogging torque compared to a 4-pole or 6-pole at the same frame size.
Sourcing and lifecycle status
For volume builds, a blanket order with scheduled releases typically secures better lead-time consistency.
