Product Description:

The MDD025B-N-100-N2G-040FD1 belongs to the MDD Synchronous Motors series produced by Bosch Rexroth Indramat. It is a compact synchronous motor for digital drive controllers and provides high-speed rotary motion to automated axes where tight velocity control is required. Its compact build helps it fit small servo axes used in packaging, handling, and similar automated equipment. This layout suits fast indexing and other motion tasks that need quick response in a small installation space. Its standard housing and balancing keep vibration within limits compatible with precision mechanical assemblies.

A centering diameter of 40 mm keeps the motor aligned with gearbox or flange hardware during mounting. Power and feedback leads exit on Side B, and the motor is supplied with a connecting cable with a coupling unit to match that orientation. At standstill, the motor can deliver 0.60 Nm of continuous torque without exceeding its thermal limit. The rotor can sustain a synchronous operating speed of 10000 rpm for extended periods, and resolver feedback supports closed-loop position and speed control. This connection layout can also simplify cable routing when the motor is installed in confined spaces. The B-length stator stack gives a torque-to-mass ratio that suits lightweight pick-and-place modules.

When power is removed, a blocking brake supplies 1.0 Nm of holding torque to help maintain axis position. This brake function is useful when the driven load must remain in place after shutdown. The motor uses the compact 025 frame size, which helps it fit into multipoint tooling stations and other small axis layouts. It is supplied without a shaft seal, so the installation should be kept free of coolant splash or abrasive dust. The output uses a plain shaft, and the rear of the motor has no secondary shaft end, which helps keep the overall length short.
