Product Description:

The MT1504A1-E2D2 is a brushless servo motor developed by Kollmorgen within the MTC Servo Motors series. Designed for closed-loop motion axes, the motor converts drive current into precise rotary displacement for pick-and-place heads, indexing tables, and other industrial automation loads. Its compact 1.3 kg frame and eight-pole rotor provide high torque density in a lightweight actuator that pairs with Kollmorgen digital amplifiers for dynamic speed and position regulation. It is suited for semiconductor handlers, labeling equipment, and other medium-speed servo axes that require accurate positioning during repetitive operating cycles.

The motor delivers a rated mechanical output of 0.37 kW at a base speed of 6000 rpm, balancing throughput with bearing life. Under continuous load, the stator draws 2.93 A RMS, and that current produces a stall torque of 0.790 N·m at 25 °C. Its magnetic coupling efficiency is represented by a torque sensitivity of 0.258 N·m/A RMS, while the generated back electromotive force measures 15.6 V RMS/krpm, which the drive must accommodate during regenerative events. The phase windings have an inductance of 9.3 mH and a DC resistance of 3.77 Ω; these parameters affect current rise time and the appropriate current-loop bandwidth.

During rapid indexing, the motor can reach a peak torque of 2.42 N·m, supported by a momentary drive current of 11 A RMS without magnetic saturation. The rotor’s low inertia of 0.0000195 kg·m² allows control loops to command high acceleration with limited overshoot when the motor is integrated into small-diameter gear stages. Heat removal is characterized by a thermal resistance of 1.37 °C/W and a thermal time constant of 15 minutes, permitting short duty surges before the winding temperature approaches its rated limit. The maximum bus voltage is 250 V RMS, which establishes the insulation and inverter requirements for the connected drive system.
