MDD025A-N-100-N2G-040PB1
The MDD025A-N-100-N2G-040PB1 is a synchronous motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for pairing with digital drive controllers, it supplies finely metered torque and velocity to miniature actuators, pick-and-place heads, and other high-speed axes in industrial automation. Its compact form suits tightly spaced machine layouts where precise motion control, quick response, and low moving mass are important during short, repetitive positioning cycles. In compact automation cells, that layout helps support fast indexing and accurate placement without requiring a larger motor frame.
The motor uses a centering diameter of 40 mm to locate precisely against mounting flanges, and wiring is completed through a rear-facing connector because the power and feedback plugs are situated on side B. At standstill, it can deliver 0.33 Nm continuously, while an integrated blocking brake supplies up to 1.0 Nm of holding torque to secure vertical or unpowered loads. Position information is generated by resolver feedback, which provides rotor angle data and tolerates the elevated temperatures common in servo compartments. Rotor balance is standard, and the housing length code A keeps overall depth minimal for tight machine envelopes.
The motor reaches a rated speed of 10000 rpm, which suits indexing tables or spindle drives that require fast acceleration with limited inertia. Power is transferred through a single-ended shaft with a keyway, and there is no rear shaft extension, so adjacent components can sit flush to the back of the motor. A fitted shaft seal helps keep coolant spray and dust away from the bearing seats in exposed installations. The 025 frame size uses a short stator stack that helps reduce mass for rapid start-stop cycles in electronic assembly equipment.
