MDD025B-N-100-N2G-040GA1
The MDD025B-N-100-N2G-040GA1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat and supplied within the MDD Synchronous Motors series. Intended for operation with digital drive controllers, the unit delivers high-speed rotation for indexing tables, small pick-and-place axes, and similar automation tasks that require compact dimensions and low rotor inertia. A blocking brake is integrated so the rotor can be locked when the system is de-energized, allowing vertical or holding applications to stay in position without external clamping. This arrangement supports precise motion in small automated equipment where quick response and secure stopping are both important.
The motor is rated for a nominal speed of 10000 rpm, meaning it can maintain that rotational velocity under rated load when driven by the matched inverter. At standstill, it produces a continuous torque of 0.60 Nm, which indicates how much static load the shaft can support without overheating during continuous operation. When the brake is engaged, it can withstand up to 1.0 Nm, which helps prevent back-driving during power loss. Commutation and position signals are supplied through resolver feedback, and this analog transducer supports smooth velocity loops and stable phase referencing. All electrical and feedback connectors face side A of the housing, which helps when cable routing must remain on one side of the actuator.
The flange has a centering diameter of 40 mm so it fits standard mounting patterns used for compact servo installations. A plain shaft is supplied, which avoids keyway stress points in clamp-style couplings. Contamination ingress is limited because a shaft seal is installed at the output end. With a frame designation of 025 and length code B, the stator package remains short enough for tight machine spaces while still supporting the motor's intended duty. The short housing also leaves more clearance for couplings, guards, and adjacent machine components.
