Torque and speed envelope for the application
The MH31402P06A2200 delivers 16.34 Nm nominal torque at 1000 rpm when paired with an LXM52 or LXM62 drive at 115 V three-phase input, dropping to 10.17 Nm at 3500 rpm on 400 V or 480 V three-phase supply. Peak stall torque reaches 55.5 Nm across the 115...480 V three-phase range, giving a 3.4x overload margin for acceleration and deceleration transients. Continuous stall torque is 18.5 Nm at rated current of 16.83 A, with a maximum current Irms of 57.42 A for short-duration peak moves. Maximum mechanical speed is 4000 rpm, with the nominal speed band adjustable via the drive parameters between 1000 and 3500 rpm depending on supply voltage.
Encoder feedback and electrical interface
Single-turn SinCos Hiperface encoder provides absolute position feedback within one revolution — no homing sequence needed on power-up for rotary applications that stay within a single turn. Electrical connection uses rotatable right-angled connectors, allowing the cable exit orientation to be adjusted in the field without disassembling the motor. Stator resistance is 0.23 Ohm and inductance is 2.99 mH, which sets the electrical time constant at roughly 13 ms — relevant for tuning current-loop bandwidth in the drive. Back EMF constant is 70.7 V/krpm, so at 3500 rpm the motor generates about 247 V line-to-line — the drive DC bus must stay above this to maintain current control.
Mounting dimensions and mechanical interface
Motor flange size is 140 mm (5.5 in) with a centring collar diameter of 130 mm and depth of 3.5 mm — mounts to the standard IEC B5 flange pattern using four 11 mm mounting holes. Shaft is 24 mm diameter, 50 mm length, smooth (no keyway) — the smooth shaft allows direct coupling with a clamping-type shaft collar or a zero-backlash coupling that grips the full diameter. Overall length is 192 mm (7.6 in) from the mounting face to the rear of the housing — factor this into the cabinet depth when the motor is mounted with the connector rotated to the side. Maximum radial force at the shaft centre is 2240 N at 1000 rpm, derating to 1550 N at 3000 rpm — belt-drive applications must stay within this envelope to avoid bearing overload.
Thermal management and environmental rating
Cooling is by natural convection — no external fan or forced air required, but the motor must be mounted with free air circulation around the housing to dissipate the 3730 W continuous power. IP65 protection means the motor body is dust-tight and protected against low-pressure water jets from any direction — suitable for washdown areas but not for submerged or high-pressure spray applications. Copper winding hot-spot temperature is rated at 135 °C (275 °F), with the torque constant specified at 120 °C — the motor can run hot but the drive must apply I²t thermal protection to prevent winding damage.
No holding brake on this variant — if the application requires a brake for vertical-axis holding, the equivalent part with brake should be specified instead. Single unit per package; the sizing reference MH31402P anchors the frame size and winding configuration for cross-referencing within the MH3 family.
