MDD021A-N-100-N2G-032FC0
MDD Synchronous Motors
The Bosch Rexroth Indramat MDD021A-N-100-N2G-032FC0 is part of the renowned MDD Synchronous Motors series, engineered for precision in industrial automation. As a Motor for digital drive controllers, it delivers reliable performance, featuring a torque constant at 20 °C of 0.19 Nm/A and a theoretical maximum torque of 0.64 Nm. With a nominal speed of 10000 min⁻¹, this AC servo motor is tailored for high-speed, dynamic applications where rapid response and accurate positioning are critical.
In terms of technical specifications, the MDD021A-N-100-N2G-032FC0 offers a windings resistance at 20 °C of 18 Ohm, providing stable electrical characteristics under varying loads. The motor uses resolver feedback to ensure precise angle measurement and robust control, while its standard balancing minimizes vibration at peak speeds. Its compact design, defined by a motor size of 021 and a centering diameter of 32 mm, integrates seamlessly into digital drive systems. The connection type is a connecting cable with coupling unit, simplifying installation and maintenance in complex machinery.
Additional features emphasize durability and operational efficiency. The housing conforms to IP65 protection (output shaft IP50), safeguarding internal components from dust and water ingress in harsh environments. Rated for a permissible ambient temperature of 0 … +45 °C, the motor maintains performance across a broad temperature range. The design excludes a blocking brake and shaft seal, reducing mechanical complexity while preserving reliability. This motor’s combination of high-speed capability, precise feedback, and rugged protection makes it an ideal choice for demanding industrial automation, delivering enhanced throughput, minimal downtime, and consistent process quality.
