MDD025C-N-100-N2K-040PA0
The MDD025C-N-100-N2K-040PA0 is a brushless AC motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Engineered for digital drive controllers, it serves compact pick-and-place heads, small spindle drives, and other axes that need high-speed positioning accuracy in industrial automation. Its brushless design supports smooth commutation and low wear during repeated indexing cycles. This arrangement lets the drive regulate speed and position accurately on small servo axes. The motor also supports internal thermal monitoring so the drive can react to rising temperature during operation.
This model supplies a continuous standstill torque of 0.90 Nm, giving the controller a predictable load reference when the rotor is locked. Its nominal mechanical velocity reaches 10000 rpm, making it suitable for rapid cyclic tasks where short move times are critical. A centering diameter of 40 mm aligns the motor housing concentrically on machine frames, which helps minimize radial runout. The centered mounting face helps maintain coupling alignment on compact mechanical stages. Power and feedback conductors exit on side A, and the motor uses a keyed connector interface so cabling can be attached without terminating individual cores. The compact housing layout helps the motor fit into machine assemblies where installation space is limited.
The unit is supplied without a blocking brake, so position holding during power-off must be handled by the drive or external mechanics. Rotor position is reported through resolver feedback, and an integrated absolute encoder in the same endbell supports homing-free startups. The output shaft is ground with a keyway for positive torque transmission, and it is protected with a shaft seal to limit lubricant migration toward the bearings. Standard dynamic balancing keeps vibration within ISO class limits. The single-ended shaft with no side B extension simplifies mounting inside tight spaces.
