The MH31002P17F2200: This is a three-phase servo motor (MH3 series) with a 100 mm flange, designed for the Lexium 52 and 62 drive families. The nominal speed of 4000 rpm and continuous power of 2270 W suit it for high-speed pick-and-place, packaging, or spindle applications where the load profile demands sustained torque at speed. Nominal torque is 5.67 Nm at 115 V three-phase (LXM52 drive), derating to 4.2 Nm at 480 V three-phase — the voltage-dependent torque curve means the drive supply voltage directly sets the usable continuous torque. The holding brake delivers 5.5 Nm of static torque — enough to hold a vertical load up to that value without servo power, but note the brake pull-in power is 12 W, which must be factored into the cabinet thermal budget if the brake is engaged for long periods.
Encoder feedback and electrical interface — what connects where
The Multiturn SinCos Hiperface encoder provides absolute position feedback over 4096 revolutions, meaning the drive knows the shaft position at power-up without a homing sequence — critical for applications where a loss-of-power restart must resume from the last known position. The resolver-style SinCos signals also give fine interpolation for low-speed ripple control. Electrical connection uses rotatable right-angled connectors, which helps in tight cable trays or when the motor is mounted in a confined space — the connector body can be oriented to point the cable exit in the best direction before tightening. Stator resistance is 1.97 Ohm and inductance is 8.24 mH — these values set the electrical time constant and influence the drive's current-loop tuning. The torque constant of 1.19 Nm/A means the drive must supply 4.77 A to reach the nominal torque of 5.67 Nm, well within the maximum continuous current of 17.5 A. Back EMF constant is 78 V/krpm — at 4000 rpm the motor generates 312 V back-EMF, which must be below the drive's DC bus voltage to maintain current control. For a 480 V drive with ~680 V DC bus, this is fine; for a 230 V drive (~325 V DC bus), the maximum speed is limited to about 4000 rpm before the back-EMF approaches the bus voltage.
Mechanical fit and environmental sealing — what the flange and IP rating mean
The motor mounts to an international standard flange with a 100 mm pilot diameter and 9 mm mounting holes on a bolt circle — this is the common IEC 72-1 frame size for servo motors in this power class. The centring collar depth is 3.5 mm, so the mating flange must have a matching recess to centre the motor accurately. Shaft diameter is 19 mm with a parallel key (6 mm key width) and 40 mm shaft length — standard for direct coupling to a load via a flexible jaw coupling or timing pulley. The shaft end has no second shaft extension, so an external encoder or brake cannot be added on the rear. IP65 protection means the motor body and connector are sealed against dust ingress and low-pressure water jets — suitable for washdown environments in food processing or machining centres where coolant spray is present. The sealing relies on the connector being properly mated and the shaft seal intact; if the motor is mounted shaft-up, a drip loop in the cable prevents water tracking into the connector. Maximum radial force at the shaft is 990 N at 1000 rpm, dropping to 620 N at 4000 rpm — this is the bearing load limit for belt-drive or overhung pulley applications. Exceeding these forces shortens bearing life; for a timing belt drive at 4000 rpm, the belt tension must be set so the resultant radial load stays under 620 N.
