Product Description:

The MDD025B-N-100-N2K-040PL1 synchronous motor is produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for direct coupling to digital drive controllers, it turns drive commands into high-speed rotary motion for compact automation axes such as pick-and-place heads and miniature spindles. The unit uses size code 025 with the B length variant and has standard rotor balancing with a standard housing. A single shaft end is provided on side A, and position data are delivered through an integrated feedback system. Its compact format suits machine layouts where low moving mass and quick response are important.

Mechanical interface dimensions support repeatable mounting. The centering pilot measures 40 mm, and electrical terminations exit on the left side through a locked connector. During continuous stall operation, the motor can deliver 0.60 Nm of torque without exceeding its thermal rating, while dynamic movement is enabled by a nominal shaft speed of 10000 rpm. The B length frame maintains magnetic loading without enlarging the footprint, and the side connection helps route cables in compact machine spaces. Such performance suits precision handling equipment that must accelerate light loads and maintain stable low-torque hold positions.

Protection and feedback elements complete the functional package. The integrated blocking brake produces 1.0 Nm of holding torque, preventing drift on vertical axes or any axis that must remain fixed when the drive is disabled. Rotary power is transmitted through a shaft machined with a keyway, and a fitted shaft seal helps keep lubricant inside the front bearing while resisting splash entry from the machine enclosure. For loop control, the motor uses resolver feedback, allowing the connected controller to track rotor angle with high immunity to electrical noise. The feedback method is well suited to compact equipment that operates near other electrical devices.
