Product Description:

The MT1502A1-E2D1N2 is a brushless servo motor produced by Kollmorgen within the MTC Servo Motors series. In automated machinery, it serves as an electromechanical actuator, converting drive current into precise rotary motion that can be tightly regulated by a servo amplifier and feedback loop. The eight-pole rotor has a back electromotive force constant of 12.2 V RMS per krpm, supporting predictable speed-related voltage behavior in the drive system.

Under continuous duty, the motor delivers 0.23 kW of mechanical power at a rated shaft speed of 6000 rpm. To maintain that operating point, the winding draws a steady 2.21 A RMS, while short transients such as rapid indexing are supported by a peak demand of 7.2 A RMS. Torque develops in proportion to phase current at a gradient of 0.202 N·m/A RMS, so a full-load condition produces approximately 0.45 N·m. The acceleration capability reaches 98,013 rad/s², allowing fast starts when the load moment matches the rotor inertia. Static friction is limited to 0.0072 N·m, minimizing breakaway torque requirements. This low static friction also helps controllers maintain smooth motion at low shaft speeds.

The stator windings have an inductance of 13.2 mH and a line resistance of 6.85 ohms, which affect current rise time and copper losses during servo tuning. Drives may supply up to 250 V RMS without exceeding the insulation limits, providing sufficient margin for high-speed regeneration events. The embedded rotor has an inertia of only 0.0000127 kg·m², enabling close adherence to changing velocity commands. Thermal loading is managed through a housing thermal resistance of 1.33 °C/W. The thermal time constant of 12 minutes indicates how quickly the winding temperature responds to changes in load. The motor weighs 1.1 kg, which simplifies installation on compact motion axes and reduces the supported mass of the surrounding machine structure.
