Product Description:

The MTC324A1-R2D1 is a servo motor manufactured by Kollmorgen for the MTC Servo Motors series. It provides rotational actuation for automated machinery when driven by a compatible servo amplifier. Within production lines, the motor enables precise positioning and speed regulation for axes such as pick-and-place units, feeders, and small rotary tables.

At 25 °C, the motor can continuously deliver 2.46 N·m of stall torque while drawing 3.01 A RMS from the drive. Its torque sensitivity is 0.779 N·m per ampere, so commanded current scales predictably with the output load. The phase winding has a DC resistance of 5.45 Ω and an inductance of 38 mH, which affect the current rise time and drive tuning. Back electromotive force is 47.1 V RMS per krpm, allowing the controller to estimate speed from the generated voltage. The mechanical section supports operating speeds up to 6000 rpm. The motor provides a rated mechanical power of 1.22 kW while remaining within its thermal limits. At an ambient temperature of 40 °C, the continuous stall torque decreases slightly to 2.31 N·m.

For transient events, the winding can accept 12.7 A RMS of peak line current, producing a maximum torque of 7.41 N·m for quick acceleration or disturbance rejection. Dynamic behavior is aided by a rotor inertia of 0.0000808 kg·m², keeping the response rapid while still smoothing small load disturbances. Static friction is limited to 0.035 N·m, so minimal drive effort is needed to initiate motion. A 24 V DC brake engages when power is removed, holding the shaft at rest. Heat produced during operation conducts through the frame with a thermal resistance of 0.895 °C/W. The motor has a 25-minute thermal time constant, allowing it to absorb short overloads before reaching its temperature limit.
