MDD025A-N-100-N2G-040FE1
The MDD025A-N-100-N2G-040FE1 is a compact synchronous motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts drive current into high-speed rotary motion for tooling, conveyors, and pick-and-place arms in automated production cells. Its compact frame supports installation where several axes must fit into a limited machine envelope without crowding nearby components. The design is suited to fast-response motion tasks that require stable feedback and predictable torque during repeated start-stop cycles.
At its core performance range, the rotor reaches a nominal speed of 10,000 rpm, enabling rapid indexing cycles for light mechanical loads. During dwell periods, it supplies 0.33 Nm of continuous stall torque, and a blocking brake rated at 1.0 Nm holds the axis when control power is removed. A centering pilot of 40 mm helps align the motor concentrically with mating components, which supports smooth coupling and low vibration in compact assemblies. Power, brake, and feedback leads exit on the left side through a connecting cable with a coupling unit, which helps route cables away from adjacent moving parts. The shaft end is supplied without a rear side-B extension, so couplings can sit close to the bearing shoulder and keep the driven package short.
The motor has a length code A and a frame size of 025, which keeps the body short and reduces moving mass on small axes. Position and velocity are closed by resolver feedback, an analog sensing method that remains reliable at high speed and provides stable rotor information to the drive. The motor uses a plain shaft and is supplied without a shaft seal, making it better suited to dry, clean installation areas where minimal drag is preferred. A standard aluminum housing spreads heat across the motor body during operation. The integrated blocking brake shares the cable assembly, which reduces the number of separate external connections.
