Product details

Sizing this motor for a motion axis

The MH30703P11F2200 is a 1.54 kW continuous-power servo motor from the Schneider Electric MH3 series, built for three-phase supply and fitted with a holding brake. The 70 mm flange and 14 mm shaft with parallel key match the international standard flange pattern — it bolts directly to a gearbox or machine frame without adapter plates. Nominal torque is 28.15 lbf·in (3.18 N·m) at 1250 rpm when driven by an LXM52 or LXM62 drive on a 115 V single-phase supply; at 480 V three-phase the nominal torque drops to 20.003 lbf·in (2.26 N·m) at 6500 rpm. The peak stall torque reaches 90.3 lbf·in (10.2 N·m) across the 115–480 V three-phase range — that is the short-duration acceleration or deceleration ceiling before the drive current limit intervenes.

Brake, encoder, and connection details

The holding brake pulls in at 7 W and holds 26.6 lbf·in (3 N·m) — enough to lock the vertical axis at rest without the drive holding torque. The single-turn SinCos Hiperface encoder gives absolute position within one revolution; for multi-turn applications you need a different encoder variant in the MH3 family. Electrical connection uses rotatable right-angled connectors — the cable exit can be oriented to clear the machine frame or cable track. Cooling is by natural convection, so no forced-air ducting is needed, but the IP65 rating means the motor body and connectors withstand washdown without sealing glands.

Electrical and thermal limits

Continuous stall current is 3.91 A; maximum RMS current is 12.57 A — the drive must be sized for the peak current during acceleration, not just the continuous figure. Stator resistance is 2.65 Ω and inductance is 8.64 mH, which sets the electrical time constant and influences the current-loop tuning gains.

Frequently asked questions

What is the continuous power rating of the MH30703P11F2200 servo motor?

The continuous power is 1540 W (1.54 kW) at the rated operating point. The nominal output power varies with supply voltage: 0.42 W at 115 V, 0.75 W at 230 V, 1.32 W at 400 V, and 1.54 W at 480 V.

What encoder type does the MH30703P11F2200 use?

It uses a single-turn SinCos Hiperface encoder. This provides absolute position feedback within one revolution; for multi-turn absolute feedback, a different encoder option in the MH3 series is required.

What is the holding torque of the brake on the MH30703P11F2200?

The holding brake provides 26.6 lbf·in (3 N·m) of holding torque and consumes 7 W of pull-in power. This is sufficient to hold a vertical axis at rest without the drive maintaining torque.

What is the IP rating and cooling method of the MH30703P11F2200?

The motor is rated IP65 standard, meaning the body and connectors withstand washdown environments. Cooling is by natural convection — no forced-air ducting is required.
