Product details

2.64 kW servo with brake — the torque numbers that matter

The MH31401P16F2200 delivers 2.64 kW continuous power at 400/480 V three-phase supply. The nominal torque is 9.36 N·m at the shaft, but the holding brake is rated 18 N·m — that's nearly double the continuous torque, meaning the brake can hold a vertical load that the motor can't lift continuously.

Encoder and feedback — single-turn SinCos Hiperface

The encoder is a single-turn SinCos Hiperface type — absolute position within one revolution, no multiturn count. If your application needs absolute position over multiple turns (e.g., a ball screw axis with travel longer than one motor rev), this encoder won't track it without an external multiturn interface. The back EMF constant is 77.41 V/krpm, and the torque constant is 1.2 N·m/A at 120 °C. These values let you calculate the drive voltage needed for a given speed and the current required for a given torque — essential when pairing with a Lexium LXM52 or LXM62 drive. Stator resistance is 0.69 Ω and inductance is 6.72 mH — the electrical time constant is about 9.7 ms, which limits the current-loop bandwidth to roughly 100 Hz. Higher-performance drives may need to account for this in tuning.

Mounting and cooling — natural convection, 140 mm flange

Cooling is natural convection — no fan, no forced air required. The motor is rated IP65, which means the housing is dust-tight and protected against low-pressure water jets from any direction. In a washdown environment, the connector O-rings and shaft seal are the wet-end barrier, not just the housing. The flange is 140 mm (5.5 in) with an international standard pattern. The centring collar diameter is 130 mm with a 3.5 mm depth — this locates the motor axially on the machine frame. Mounting holes are 11 mm diameter on the bolt circle. The shaft is 24 mm diameter with a parallel key, 50 mm shaft length. Maximum radial force at the shaft end is 1930 N at 1000 rpm, dropping to 1340 N at 3000 rpm — overspeeding the bearing load limit shortens life faster than thermal overload.

Frequently asked questions

What is the holding brake rated for on this motor?

The holding brake is rated 18 N·m (159.3 lbf·in). This is roughly double the nominal torque of 9.36 N·m, so the brake can hold a vertical load that exceeds the motor's continuous lifting capacity — important for Z-axis or gravity-loaded applications where the brake takes the static load after the motor stops.
