MDD025B-N-100-N2K-040FE1
The MDD025B-N-100-N2K-040FE1 is a compact synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Intended for digital drive controllers, it supplies rapid rotary motion in tight automation axes such as pick-and-place heads and light gantry stages. The motor follows size code 025 and length code B, and its standard housing and standard balancing support direct installation while keeping vibration low for precision positioning tasks. Its compact format also suits machines where moving mass and available mounting space are both limited. This makes it suitable for short-stroke mechanisms that must accelerate quickly and stop with repeatable accuracy.
Energized by its stator windings, the motor delivers a continuous standstill torque of 0.60 Nm, allowing sustained holding or low-speed feed duties without overheating. Driven by a matched inverter, it reaches a nominal mechanical speed of 10,000 rpm, giving high surface velocity for fast positioning cycles. An integrated blocking brake provides a static capacity of 1.0 Nm, so vertical loads remain secure during power loss. The brake supports load holding when the drive is not actively energizing the motor. Mounting is simplified by a centering pilot of 40 mm, which helps align the motor accurately on the machine face. Power and feedback conductors exit on the left side of the housing, which can simplify cable routing when multiple axes are stacked closely.
Electrical interfacing uses a connecting cable with coupling unit, which eliminates a separate terminal box and keeps the connection arrangement compact. Position data is provided by an integrated absolute encoder, and the drive uses resolver feedback for closed-loop rotor position control. The output end is a plain shaft without secondary machining, and the unit is supplied without a shaft seal, so the installation should protect the bearing face from coolant spray. This arrangement supports compact machine layouts where cable access is limited around the motor body. The shaft end is limited to the drive side only, which helps reduce inertia during quick reversals and supports fast axis response.
