Product Description:

Kollmorgen’s MT1506A1-E1D1 servo motor belongs to the MTC Servo Motors series. This brushless unit is built for closed-loop motion axes on pick-and-place stages, packaging lines, and other industrial automation equipment where compact torque density is required. The frame couples directly to Kollmorgen digital drives, converting three-phase input current into rotary motion at commanded velocity and position profiles through its eight-pole permanent-magnet rotor.

The electrical constants govern continuous operation. A back electromotive force of 28.8 VRMS/krpm lets the drive estimate speed from generated voltage and establishes the required bus voltage margins. During a steady load, the stator draws a continuous line current of 2.89 ARMS, producing a continuous stall torque of 1.353 N·m while limiting the rise in copper temperature. Rated power reaches 0.67 kW at a rated speed of 6000 rpm, so the shaft can deliver mechanical work without exceeding its thermal limits. The winding resistance is 5.33 Ω, and its 14.9 mH phase inductance filters pulse-width modulation ripple from the drive. The maximum line-to-line voltage is 250 VRMS, aligning with common inverters that use a 400 V DC bus. A torque sensitivity of 0.476 N·m/ARMS supports current-loop tuning.

Dynamic limits are wider than the continuous ratings. The motor accepts transient peaks of 11.4 ARMS, enabling acceleration torque of up to 4.62 N·m for short duty cycles. Rotor mass distribution results in an inertia of 0.0000317 kg·m², supporting rapid position changes without demanding excessive drive current. Heat conducted from the windings to the housing is limited by a thermal resistance of 0.99 °C/W. Combined with a 24-minute thermal time constant, this resistance affects how long overload intervals can persist before the motor reaches its maximum temperature. The eight-pole rotor geometry also smooths cogging, providing finer low-speed resolution for indexing applications.
