MDD025A-N-100-N2K-040FF0
The MDD025A-N-100-N2K-040FF0 is a synchronous servo motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. As a motor for digital drive controllers, it delivers high-speed rotary motion that can be precisely regulated by a closed-loop control system in automated machinery such as pick-and-place heads or spindle drives. The motor works with compatible drive modules to convert electrical commands into mechanical torque, enabling accurate positioning and stable velocity profiles in multi-axis production equipment. Its compact 025 frame eases integration in confined mounting positions.
It reaches a nominal speed of 10000 rpm, allowing fast cycles when an application calls for small but rapid axis movements. At standstill, the motor can apply 0.33 Nm of continuous torque, which is suitable for holding light loads without overheating. A centering diameter of 40 mm aligns the frame to mounting fixtures, while the position transducer is an integrated absolute encoder that supplies multi-turn data to the drive. Rotor angle is also returned through resolver feedback, allowing commutation and position monitoring during operation. The unit is supplied without a blocking brake, so stopping torque must be provided electrically or by the machine mechanics. Its housing is standard, the shaft seal is omitted to reduce friction, and power and signal lines leave through a connecting cable with a coupling unit.
All external connectors exit on the right side, simplifying wiring in cabinets where drives are stacked. The output element is a plain shaft in a single-ended configuration, so side B remains closed without a shaft extension. Internal rotor balance follows Standard class, which helps limit vibration when the motor operates at high speed. The A length code indicates the shortest body within the 025 size family, helping reduce mass and inertia. A standard housing finish and the absence of a shaft seal suit the motor for clean, dry environments.
