Motor ratings that govern the axis
The MH31403P16F2200 delivers 4750 W continuous power at 750 rpm nominal speed, with a nominal torque of 196.22 lbf.in (22.17 N.m) when paired with an LXM62 drive at 115 V single-phase input. The holding brake locks the shaft at 203.6 lbf.in (23 N.m) — enough to hold a vertical load without a counterbalance when the drive is disabled. Peak stall torque reaches 663.8 lbf.in (75 N.m) across the 115...480 V three-phase range, and continuous stall torque is 212.4 lbf.in (24 N.m) at 18 A continuous stall current. The torque constant of 1.33 N.m/A at 120 °C copper temperature lets you estimate the current draw for a given load torque.
Encoder feedback and brake integration
The single-turn SinCos Hiperface encoder provides absolute position feedback on power-up — no homing sequence needed after a power cycle. The 10-pole motor pairs with this encoder resolution to deliver smooth torque at low speed. The holding brake draws 19 W pull-in power. The brake release voltage and timing must be set in the drive parameter set; the brake is spring-applied, so it engages on power loss without a separate control signal.
Mechanical mounting and environmental sealing
Mounts on an international standard flange with a 5.5 in (140 mm) flange size, centring collar diameter 5.1 in (130 mm) and depth 0.1 in (3.5 mm). The shaft is 0.9 in (24 mm) diameter, 2.0 in (50 mm) long, with a parallel key and key width 0.3 in (8 mm). No second shaft end — the rear face is sealed. IP65 rating means the motor body resists dust ingress and low-pressure water jets from any direction — suitable for washdown areas in food processing or outdoor conveyor sections. Cooling is natural convection; no fan, so the ambient temperature must stay within the copper hot limit of 275 °F (135 °C). Maximum radial force at the shaft nose is 2420 N at 1000 rpm, derating to 1670 N at 3000 rpm — belt-driven loads must respect this curve to avoid bearing overload.
Electrical connection and drive pairing
Rotatable right-angled connectors allow the cable exit to be oriented in 90° increments — useful when the motor is mounted in a tight enclosure corner. The three-phase winding has a stator resistance of 0.22 Ohm and inductance of 3 mH, giving a low electrical time constant for fast current-loop response. Maximum continuous current Irms is 62.32 A — the drive must be sized to supply this peak without current limit foldback during acceleration. Back EMF constant is 85.9 V/krpm, so at 750 rpm the motor generates about 64 V line-to-line; the drive DC bus must stay above this voltage to maintain torque control.
Sourcing and lifecycle status
The IP65 rating and Hiperface encoder are standard on this frame; confirm the cable length and connector type with the drive order.
