Product Description:

The MDD021A-N-100-N2G-032FC0 AC Servo Motor ensures high contouring accuracy even at elevated feedrates particularly during high speed machining operations. The motor offers IP65 protection rating and F insulation class.

The MDD021A-N-100-N2K-032GB0 AC servo motor supports efficient signal transmission through its resolver feedback system. The system ensures accurate position monitoring. Its compact size and low inertia make it suitable for dynamic response operations. The AC servo motor’s plain shaft enhances flexibility in installation. The shaft supports non positive torque connections to various mechanical transmission parts. The thermal characteristics (15 minutes thermal time constant) provide extended operational duration without performance degradation. The motor continuous torque of 0.15 Nm and torque constant of 0.19 Nm/A are optimized for controlled motion in industrial and automation environments. The high winding resistance of 18 ohms supports safe heat dissipation especially during high speed operation. The motor type is commonly selected for repetitive motion systems requiring consistent torque delivery and fast actuation. The MDD series AC servo motor’s Class N balancing minimizes operational vibration which is essential for maintaining motion stability and protecting coupled machinery.

The Bosch Rexroth Indramat MDD021A-N-100-N2K-032GB0 AC servo motor can handle brief acceleration spikes without overload with a peak current capacity of 3.6 A. The servo motor is compatible with DDS series drive controllers that expands its utility across different platforms. The AC servo motor is employed in high precision screwing applications, auxiliary axis control and automated tool changing mechanisms. Its precise position, speed and torque control capabilities make it ideal for tasks requiring repeatability and dynamic response such as spindle rotation during fastening, synchronization of secondary axes in multi axis systems and actuation of tool changers in CNC machinery.
