Product Description:
The MDD025A-N-100-N2K-040PB1 is a synchronous motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is intended for use with digital drive controllers, where it provides precise velocity and position control in compact automation equipment. The motor combines its power section, mechanical output, and feedback devices in one housing, making it suitable for pick-and-place units, small indexing tables, and auxiliary spindle tasks that require fast response in limited installation space. This arrangement supports closed-loop motion without adding separate external sensing hardware, which helps keep axis layouts compact and orderly.
At standstill, the rotor can supply 0.33 Nm of continuous torque, which indicates the continuous load it can hold while energized and not rotating. The motor reaches a nominal speed of 10000 rpm, allowing high surface velocity in small-diameter tools and other compact mechanisms. Mechanical alignment during installation uses a 40 mm pilot diameter, which helps the housing seat accurately on the machine interface. All power and sensor conductors exit on Side B through an integral connector, which keeps cable routing concentrated at one end of the motor. Standard balancing helps support smooth running, and the A-length housing keeps the motor short for tightly spaced machine layouts.
Position retention during power-off is provided by a blocking brake with 1.0 Nm of holding torque. Motion feedback is supplied by an integrated absolute encoder, while a resolver feedback channel also provides rotor angle information to the drive. The output shaft uses a keyway for positive torque transmission, and a shaft seal helps keep lubricant inside the bearing area while reducing the entry of contaminants. Because the design has no secondary shaft end on side B, the driven connection remains concentrated on the primary output side. This layout leaves the rear of the motor dedicated to cable exit and internal components rather than an additional mechanical interface.
