MDD025A-N-100-N2K-040PR1
The MDD025A-N-100-N2K-040PR1 is a miniature synchronous motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Designed as a direct companion to digital drive controllers, it supplies servo-grade torque for rapid positioning tasks in pick-and-place gantries, small linear stages, and light robotics. Its resolver-based feedback and internal blocking brake allow closed-loop motion and secure holding without external latching devices in space-limited installations. This arrangement helps the drive maintain smooth low-speed control during short, repetitive moves.
A centering pilot of 40 mm fixes the motor concentrically to the machine frame, preserving alignment between the rotor and driven load. At standstill it produces a continuous torque of 0.33 Nm, adequate for static preload or friction compensation while remaining within the thermal limits of the compact housing. The motor reaches a nominal speed of 10000 rpm, enabling high cycle rates when paired with suitable gear reduction. An internal brake develops 1.0 Nm of holding torque, preventing back-driving on vertical or off-axis loads whenever the drive is disabled. Position feedback is delivered through resolver feedback, which provides rotor angle information with strong noise immunity over long cable runs in industrial environments.
Machine wiring is simplified because the power, sensor, and brake lines exit to the right through a single circular connector. Standard rotor balancing minimizes vibration at full speed, and a compliant housing seal is reinforced with a shaft seal that helps block lubricant migration and airborne contaminants. The single-ended shaft follows a keyway profile, which provides positive torque transmission to couplings or pulleys. This layout supports compact machine designs that need orderly cable routing and a sealed shaft outlet.
