Product Description:

The MDD025B-N-100-N2G-040FE1 is a compact synchronous servo motor manufactured by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. The unit is engineered for integration with digital drive controllers, where it converts precisely timed stator currents into controlled rotary motion used in pick-and-place heads, light conveyors, and electronic assembly stations. Its small frame supports installations that demand high speed and limited mass inside confined machine envelopes.

The motor delivers a continuous stall torque of 0.60 Nm, which is the maximum load it can hold indefinitely without overheating when the rotor is locked. Its rotor is balanced to the standard grade, limiting vibration at the rated operating point. A nominal speed of 10000 rpm allows rapid indexing cycles, while the size 025 frame and B length code keep the motor compact and help minimize moment of inertia. Motion feedback is provided by resolver feedback, enabling analog position data for the drive’s commutation loops. The electrical terminations exit on the left side of the housing and are pre-assembled into a connecting cable with a coupling unit; this orientation simplifies cabinet routing when the motor is mounted on narrow linear axes. The housing follows a standard uncooled design, and the rotor centering diameter is 40 mm for repeatable mounting.

In stop-state scenarios, the integrated blocking brake develops 1.0 Nm of static torque, letting the axis hold position without drive current. Power is delivered through a plain shaft suited to clamp or friction hubs, and the mechanical interface is simplified because the output is supplied without a shaft seal, eliminating contacting elements that can wear in dry-room equipment. The motor is also factory configured without a side B shaft end, permitting the rear face to mount flush against gearboxes or brackets and keeping the overall package short for dense multi-axis installations managed by coordinated drive electronics.
