MDD025B-N-100-N2K-040PL0
The MDD025B-N-100-N2K-040PL0 is a synchronous servo motor produced by Bosch Rexroth Indramat and is part of the MDD Synchronous Motors series. The unit is intended for use with digital drive controllers where high-speed rotary motion is required in pick-and-place modules, compact tooling axes, or packaging spindles. By converting electrical energy from the controller into precise mechanical torque, the motor serves as the actuation stage in closed-loop industrial automation. Its compact format also suits machine sections where mounting space is limited but fast and repeatable motion is still required.
The motor is designed for applications that demand speeds up to 10000 rpm, and this high nominal speed supports short cycle times when paired with a suitably rated inverter. At standstill, it can deliver a continuous torque of 0.60 Nm, giving adequate holding force for light indexing tables or grippers without overheating. Proper mechanical centering is achieved through a 40 mm pilot diameter that fits standard flange patterns and helps keep radial runout low. Service wiring is simplified because both power and resolver plugs exit on the left side of the housing, which can reduce cable loops in compact machine layouts. A keyed circular connector interface supports secure electrical connection while keeping the connection sealed.
Position data for the drive is provided by resolver feedback, and an auxiliary channel from the integrated absolute encoder supports multi-turn indexing without homing routines. To keep lubricant inside the bearing cavity, the shaft is supplied with a shaft seal, which helps limit contamination around the bearing area during operation. The keyway shaft end accepts couplings directly, and because the motor is supplied without a blocking brake, external holding measures are required when power is removed. Size code 025 and length code B keep the overall package compact for tight machine frames, and that smaller envelope can be useful where adjacent components are installed close together.
