Torque and speed across the drive voltage range
The MH31402P12A2200: This MH3 series servo motor delivers 16.34 Nm nominal torque when paired with an LXM52 or LXM62 drive at 115 V three-phase, dropping to 10.17 Nm at 400/480 V three-phase — the torque constant of 1.1 Nm/A at 120 °C copper hot sets the current-to-torque relationship for the application. Continuous power reaches 3.73 kW at 400/480 V three-phase, with continuous stall torque of 18.5 Nm across the 115–480 V three-phase range — the 57.42 A maximum current and 16.83 A continuous stall current define the drive sizing envelope.
Feedback and environmental sealing for production lines
The multiturn SinCos Hiperface encoder provides absolute position feedback over multiple shaft revolutions — this eliminates the need for a homing sequence on power-up in applications like pick-and-place or rotary indexing tables. IP65 rating means the motor body and connector interface withstand washdown from hosed liquids and airborne dust — suitable for food processing, packaging, or machining lines where coolant spray is present. Rotatable right-angled connectors allow the cable exit orientation to be adjusted on-site by up to 270°, simplifying cable routing in tight panel-to-machine transitions without adding a junction box.
Mechanical interface and mounting constraints
The 140 mm flange (5.5 in) with four 11 mm mounting holes on a 130 mm centring collar and 3.5 mm centring collar depth matches the IEC standard flange pattern — the motor bolts directly to the machine frame without an adapter plate. Shaft diameter is 24 mm with a parallel key and 50 mm shaft length — the 2240 N maximum radial force at 1000 rpm drops to 1550 N at 3000 rpm, so bearing life at higher speeds depends on the belt or coupling preload. Overall length is 192 mm (7.6 in) without a brake — the natural convection cooling requires free air movement around the finned housing, so panel-mounting with less than 50 mm clearance on the non-drive end will derate the continuous torque.
Electrical parameters for drive commissioning
Stator resistance of 0.23 Ω and inductance of 2.99 mH give an electrical time constant of 13 ms — the drive's current loop gains must be tuned to this L/R ratio for stable torque control without overshoot. Back EMF constant of 70.7 V/krpm means at 3500 rpm the motor generates 247 V line-to-line — the drive DC bus voltage must exceed this peak plus the voltage drop across the stator resistance at full current to maintain field-oriented control. Peak stall torque of 55.5 Nm at 115–480 V three-phase provides the overload headroom for acceleration and deceleration — the 57.42 A maximum current is the limit the drive must supply during this transient.
The motor ships as a single unit (package quantity of 1) with the international standard flange and rotatable connectors — the IP65 rating and Hiperface encoder are factory-configured and not field-upgradable.
