Product Description:

The MDD025B-N-100-N2G-040FC0 is a miniature servo unit manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for use with digital drive controllers, this motor supplies closed-loop rotary actuation for compact handling stations, light gantries, and electronic assembly rigs. A low-inertia rotor, resolver interface, and slender frame help the motor respond quickly to command changes while maintaining repeatable positioning during continuous production duty. Its compact format also makes it suitable for installations where axis spacing and available mounting space are limited.

The motor reaches a nominal speed of 10000 rpm, allowing high surface velocities in limited travel distances. At standstill, it sustains 0.60 Nm of continuous torque, so it can hold fixtures or index positions without overheating during normal operation. Position and velocity are measured through resolver feedback, which provides robust angular data with good resistance to electrical noise. A plain shaft on the output side simplifies coupling selection and helps minimize runout in precision stages. Mounting is referenced to a 40 mm centering diameter that aligns the stator coaxially with gearheads or flanges and helps limit radial misalignment. The aluminum housing is the standard variant, and motor length code B is used with the winding arrangement for this speed and torque range.

The motor uses a factory-terminated connecting cable with coupling unit, which simplifies installation in modular cells. Power and feedback connections are oriented on Side A, so cable routing can be arranged around the available machine space. The motor is supplied without a blocking brake, making it suitable for drive systems where holding torque is provided by the controller or by external mechanical retention. Rotor mass is adjusted to meet standard balancing quality, which helps keep vibration low during continuous high-speed operation. A plain shaft end and the absence of a shaft seal reduce frictional losses and help the motor fit into space-limited housings where compact dimensions are important.
