MDD025A-N-100-N2G-040PL0
The MDD025A-N-100-N2G-040PL0 is a compact synchronous motor from Bosch Rexroth Indramat in the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts commanded current into precise mechanical rotation for pick-and-place heads, light machining spindles, and small indexing tables. When paired with a compatible drive, it supports closed-loop axis control in industrial automation cells where space is limited and fast, accurate motion is required. This format is also suitable for compact machine modules that need repeatable positioning without a large motor envelope.
With motor size 025 and length code A, the unit keeps a compact footprint while delivering a continuous standstill torque of 0.33 Nm. This output is suitable for light-load holding and controlled starts. During motion it reaches a rated speed of 10000 rpm, which fits high-cycle axes that need rapid response. A centering diameter of 40 mm helps align the motor to machine frames and reduce runout at the mounting interface. The power and feedback connectors are positioned on the left side, which can simplify routing in tight installations. A shaft seal protects the front bearing from lubricant loss and airborne contaminants. Standard balancing and the housing layout help keep operation smooth at elevated speed.
Electrical and sensor connections are made through a single connector, avoiding separate terminal points for these circuits. Using one connection point can also reduce exposed wiring at the motor body. Position information is supplied by integrated resolver feedback, so the drive can calculate rotor angle during rapid acceleration and maintain stable commutation. Because the motor is supplied without a blocking brake, any holding force at standstill must come from the drive or from external clamping hardware. The output shaft has a keyway, allowing torque transfer through keyed pulleys or couplings, while side B remains closed. A fitted shaft end cover helps protect the enclosure during high-speed operation.
