Product details

Three-phase servo with holding brake — 1540 W continuous

The MH30703P12F2200 is a three-phase servo motor from the Schneider Electric MH3 family, rated 1540 W continuous power with a holding brake and a multiturn SinCos Hiperface encoder for absolute position feedback. Nominal torque reaches 28.15 lbf.in (3.18 N.m) at 115 V three-phase supply, and the peak stall torque is 90.3 lbf.in (10.2 N.m) across the 115–480 V three-phase range — useful for sizing the drive's peak current capability. The IP65 rating means the motor body is dust-tight and protected against water jets, so it can be mounted in washdown zones or wet environments without a secondary cover.

Speed-torque envelope and drive matching

Nominal speed varies with supply voltage and drive model: 1250 rpm at 115 V single-phase, up to 6500 rpm at 480 V three-phase — the speed-torque curve shifts with the DC bus voltage, so the drive must be selected for the target operating point. The torque constant is 0.87 N.m/A at 120 °C copper temperature, which means the drive's current loop must deliver the commanded torque within the motor's thermal limit — the continuous stall current is 3.91 A, and the maximum RMS current is 12.57 A.

Mounting and mechanical interface

The motor flange is 70 mm (IEC standard), with a centring collar diameter of 60 mm and a depth of 2.5 mm — this mates directly with common gearbox input flanges and mounting brackets without an adapter plate. The shaft is 14 mm diameter with a parallel key, 30 mm shaft length, and the motor has no second shaft end — the load couples through the keyed shaft only. Electrical connection uses rotatable right-angled connectors — the connector orientation can be adjusted in the field to route cables away from moving parts or obstructions.

Frequently asked questions

What is the MH30703P12F2200's continuous power rating?

The continuous power is 1540 W, with a continuous stall torque of 30.09 lbf.in (3.4 N.m) across the 115–480 V three-phase range.

What encoder type does the MH30703P12F2200 use?

It uses a multiturn SinCos Hiperface encoder, which provides absolute position feedback over multiple revolutions — suitable for high-accuracy positioning without a home cycle on power-up.

Does the MH30703P12F2200 include a holding brake?

Yes, it includes a holding brake with a holding torque of 26.6 lbf.in (3 N.m) and a brake pull-in power of 7 W — the brake engages on power loss to hold the load stationary.
