Product Description:
The MDD090B-N-030-N2L-110PB1 is a synchronous drive unit produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts commanded current into torque for positioning tables, tooling spindles, and other automated axes. Its compact construction supports mounting in tight machine spaces where available installation depth is limited. This layout makes the motor suitable for equipment that needs precise rotary motion without adding unnecessary bulk around the drive axis.
At its rated operating point, the unit delivers a continuous standstill torque of 7.2 Nm, giving stable holding force for static loads without overheating. During starts and emergency stops, the integrated blocking brake can apply 6.5 Nm of torque to secure the shaft. The rotor reaches a nominal speed of 3000 rpm, which suits digital servo systems that require a broad operating range. A centering diameter of 110 mm aligns the housing on the machine frame, while the standard balancing grade helps limit vibratory forces during rotation. The motor has frame size 090 and length code B, which place it in a compact housing without additional cooling attachments.
The electrical and feedback interfaces are positioned on side B, where a connector carries power and encoder signals to the drive. Position data is generated by digital servo feedback (DSF), allowing the controller to monitor rotor motion continuously and correct command deviations during operation. The output shaft uses a keyway profile for positive torque transmission to couplings or driven components. It is also equipped with a shaft seal to help block contamination at the shaft passage. All service lines are routed flat against the housing for cleaner cable management in confined installations, and the opposite shaft end is omitted to match the single-ended configuration.
