3.73 kW servo with holding brake for vertical-axis loads
The MH31402P07F2200 is a three-phase servo motor from the Schneider Electric MH3 series, delivering 3.73 kW continuous power at 400/480 V supply. Nominal speed is 3000 rpm, with a continuous stall torque of 18.5 N.m across the 115...480 V range. Peak stall torque reaches 55.5 N.m for acceleration and deceleration transients, limited to the 3-second peak current rating of 46.22 A.
Multiturn absolute encoder and IP65 sealing
The Multiturn SinCos Hiperface encoder provides absolute position feedback over multiple shaft revolutions — no homing cycle needed after power loss. This is critical for applications like gantry robots or tool changers where position must be retained. IP65 standard protection means the motor body is sealed against dust ingress and low-pressure water jets from any direction. Suitable for washdown environments in food processing or machining coolant splash — but the connector must be properly mated to maintain the seal. Rotatable right-angled connectors allow the cable exit to be oriented in 90° increments, simplifying cable routing in tight cabinets or on moving axes.
Torque and speed ratings across drive voltages
Nominal torque varies with the drive voltage and type: 16.34 N.m with LXM52 at 115 V three-phase, 14.0 N.m with LXM52 at 230 V single-phase, and 10.17 N.m with LXM52 at 400 V or 480 V three-phase. The same pattern applies for LXM62 drives. The torque constant is 1.24 N.m/A at 120 °C copper temperature — use this to calculate the RMS current required for a given load torque profile. Back EMF constant is 70.7 V/krpm, which determines the DC bus voltage needed to reach rated speed. Stator resistance is 0.23 Ohm and inductance is 2.99 mH — these values feed into the drive's current loop tuning and I²R loss calculation for thermal modelling.
Mechanical interface and mounting constraints
The motor flange is 140 mm (5.5 in) with an international standard flange pattern — mounting holes at 11 mm diameter on a 130 mm centring collar. Centring collar depth is 3.5 mm. Smooth shaft (no keyway) with 24 mm diameter and 50 mm shaft length. A clamping-type coupling or shaft collar is required — set-screw couplings on a smooth shaft risk slipping under peak torque. Maximum radial force at the shaft end is 2240 N at 1000 rpm, derating to 1550 N at 3000 rpm. Exceeding these limits shortens bearing life — check the driven load's overhung force against the speed curve. Overall motor length is 227 mm (8.9 in) excluding the connector and cable bend radius. Natural convection cooling — no fan, so the motor relies on its own surface area and mounting plate for heat dissipation.
Active production — sourcing and lifecycle
Sourced through authorized distribution channels. No minimum order quantity restrictions beyond standard packaging (1 unit per package). No official successor or cross-reference part is recorded — this is the current production variant for the MH3 frame size at 3.73 kW with holding brake and Hiperface encoder.
