MDD025B-N-100-N2G-040FB1
The MDD025B-N-100-N2G-040FB1 is a brushless synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is intended for use with digital drive controllers as the rotary actuator in automated machinery that requires high-speed positioning and closed-loop control. When paired with a compatible controller, this compact motor delivers commanded torque to conveyor rollers, indexing tables, and other motion axes while returning actual shaft-angle data to the control system. This operating role makes it suitable for machines that need accurate starts, stops, and short positioning moves throughout repeated production cycles.
At standstill, the motor can deliver 0.60 Nm of continuous torque, allowing it to hold or slowly advance small mechanical loads without overheating. During dynamic cycles, it can reach a rated speed of 10,000 rpm. The motor includes a blocking brake with 1.0 Nm of holding torque when power is removed, which helps prevent back-driving on vertical axes. Accurate mechanical centering is achieved through a 40 mm pilot diameter on the front flange, and the power and feedback connectors exit on Side B to keep cabling clear of the driven shaft. All electrical terminations use a circular connector interface, and this arrangement keeps the wiring layout compact in installations with limited space around the motor body.
Motion feedback is provided by resolver feedback, which tolerates high rotational speeds and electrical noise. The rotor uses standard balancing, and the housing has a motor length code B that fits tight machine frames while providing the winding space needed for this motor size. A plain shaft without a keyway minimizes runout in precision couplings, and the design omits a shaft seal to reduce friction. The housing follows the standard MDD enclosure style, and the single-ended shaft arrangement leaves the opposite end free of mechanical output. This layout suits clean coupling arrangements where low friction and accurate shaft alignment are important during continuous servo operation.
