Product Description:

The MT304B1-M2C1 is a brushless servo motor produced by Kollmorgen and supplied under the MTC Servo Motors series. This motor serves as a precision actuator that applies accurately regulated torque and velocity to machine shafts, enabling coordinated motion in automated assembly lines, robotics, and high-speed material-handling stations.

The motor can deliver a continuous shaft load of 2.45 N-m while drawing a line current of 5.26 ARMS, allowing sustained operation without overheating at 40 °C ambient. A rated mechanical speed of 6000 rpm combines with a rated electrical output of 1.31 kW to match mid-range servo drives that supply up to 250 VRMS on the power leads. The torque constant is 0.473 N-m/ARMS, so each ampere of phase current produces nearly half a newton-meter of torque, a figure that links drive current limits to mechanical output. Back electromotive force is 28.6 VRMS per 1000 rpm, signaling the voltage generated at synchronous speed, while a DC resistance of 1.79 Ω and an inductance of 14.0 mH shape the electrical time constant and influence current-loop tuning. Continuous operation is supported whenever bus voltage remains below the 250 VRMS ceiling.

Dynamic overload capacity is defined by a peak torque of 7.41 N-m and a peak line current of 20.9 ARMS, giving short bursts of force for rapid indexing. The lightweight rotor, with an inertia of 0.0000808 kg-m², permits a calculated maximum angular acceleration of 91 714 rad/s², so axes can start and stop within milliseconds. Thermal saturation is delayed by a winding time constant of 25 min, providing ample margin for intermittent high-duty cycles. Mechanical integration is straightforward because the housing length is 137.7 mm and the total weight is 3.3 kg, dimensions that fit compact drive assemblies without adding significant mass.
