MDD025A-N-100-N2G-040PA0
The MDD025A-N-100-N2G-040PA0 is a compact synchronous motor manufactured by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Classified for use with digital drive controllers, it converts commanded electrical input into precise rotary motion for tightly regulated automation cells, conveyor diverters, and compact tool heads. Its A-length housing and 025 frame support installation in narrow equipment bays where short response time and low moving mass are important. This makes the motor useful on small indexing axes and feed mechanisms that need repeatable motion in a limited installation space.
Mechanical alignment is supported by a centering pilot measuring 40 mm, which helps seat the motor accurately on gearboxes and mounting flanges. The rotor is factory balanced to the standard grade, reducing vibration at the nominal speed of 10000 rpm. Under continuous stall conditions, the motor delivers 0.33 Nm of torque for rapid micro-axis corrections in compact motion systems. Power and feedback conductors exit on Side A through a single industrial Connector, which helps keep cable routing compact in multi-axis assemblies. The shaft uses a keyed profile for positive coupling to compatible hubs and pulleys. The compact housing also helps the motor fit tightly spaced machine layouts without adding unnecessary bulk.
Control relies on resolver feedback, which supplies rotor position information to the drive for commutation and closed-loop speed regulation. The motor is supplied without a blocking brake, so holding force during power-off conditions must come from the drive or from external mechanical retention. The output shaft uses a keyway design, and it is supplied with a shaft seal to help protect the internal bearing area from coolant splash and airborne particles. This combination supports dependable operation in compact machinery where contamination control and secure torque transfer are both important. The motor also keeps a single-shaft layout and a standard exterior finish for straightforward integration into small servo-driven assemblies.
