Product Description:

The MTC726B1-R1C1 servo motor is built by Kollmorgen and belongs to the MTC Servo Motors series. It is a permanent-magnet, brushless unit designed to provide closed-loop torque and velocity control for automated machinery such as gantries, presses, and indexing stations. An eight-pole rotor gives the unit high magnetic resolution, allowing precise positioning with low cogging while supporting the rapid acceleration demanded in modern production cells.

Under steady thermal conditions at 25 °C, the motor can deliver a continuous stall torque of 53.7 N-m, while at 40 °C the rating falls slightly to 50.4 N-m. Producing this torque requires only 18.3 ARMS of line current because the torque sensitivity is 2.75 N-m/ARMS. The winding includes a 0.553 ohm DC resistance and a back electromotive force of 166.5 VRMS/krpm, which affect drive-side voltage selection. At its rated operating point, the shaft outputs 9.8 kW of power. The electromagnetic brake engages at 24 VDC to hold position during downtime, and the drive may call on 64.7 ARMS of peak current for acceleration or disturbance rejection.

For short bursts, the actuator can reach a peak torque of 152.3 N-m, giving machines substantial overload capacity for cutting or pressing strokes. Dynamic response is influenced by the rotor inertia of 0.0126 kg-m², which balances quick speed changes with stable running. Coil inductance is 18.5 mH, shaping current rise time and smoothing ripple when the inverter switches. During prolonged cycles, heat moves from the windings to the housing through a thermal resistance of 0.248 °C/W, and temperature rise follows a long thermal time constant of 72 min, allowing extended duty before equilibrium is reached. Static friction is limited to 0.584 N-m, so small control efforts can overcome breakaway without oscillation.
