MDD093C-N-020-N5L-110PA0
MDD Synchronous Motors
The Bosch Rexroth Indramat MDD093C-N-020-N5L-110PA0 is part of the renowned MDD Synchronous Motors series and delivers precision control at a nominal speed of 2000 min⁻¹ with a theoretical maximum torque of 74.6 Nm. This Motor for digital drive controllers features a motor size 093 frame and a motor length code C, providing a versatile footprint for industrial automation systems. Housed in a standard housing with IP 65 protection category, the unit is built to withstand harsh environments while maintaining clean operation. It incorporates a shaft seal for contaminant exclusion and a balancing standard design to minimize vibration at high speeds.
With a peak current of 140.4 A and a continuous torque at standstill of 24.0 Nm (35.0 Nm peak), this servo motor ensures reliable torque delivery even under locked-rotor conditions. The torque constant at 20 °C of 0.77 Nm/A and a measured windings inductance of 3.9 mH offer predictable current-to-torque conversion and smooth dynamic response. A robust thermal time constant of 50 min (45 min steady-state) limits thermal buildup during frequent load cycles, while the absence of a blocking brake simplifies maintenance without compromising safety. Signal integrity is driven by high-resolution digital servo feedback (DSF), and the connection direction Side A layout streamlines cabinet integration.
Engineered without a blocking brake and with a centering diameter of 110 mm, the MDD093C series motor mounts securely in compact assembly spaces. Its standardized connectors and compact design facilitate rapid installation and interchangeability across synchronized drive networks. With industrial-grade durability and precision feedback, this synchronous motor is optimized for demanding applications in robotics, CNC machining, and high-performance automation systems.
