Product Description:

The MDD025A-N-100-N2G-040FF0 is a compact synchronous motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Designed for digital drive controllers, it supplies high-speed rotary motion that can be accurately regulated by the accompanying drive in automated machinery, pick-and-place heads, or miniature spindle stations. The motor suits installations where limited space and rapid acceleration are priorities, serving as the electromechanical element that translates commanded current into controllable shaft torque. Its compact format makes it suitable for tightly spaced machine layouts where short travel distances and responsive motion are important. In these applications, the motor is typically used on light-duty axes that require fast directional changes and stable speed control rather than heavy continuous loading.

A centering diameter of 40 mm aligns the housing against gearboxes or adapter plates. Power and feedback conductors exit on the right side, and a connecting cable with a coupling unit permits quick detachment when the motor must be separated from the machine. At standstill, the rotor delivers a continuous 0.33 Nm of torque through the standard balancing and housing arrangement. The electromagnetic design supports a nominal mechanical speed of 10000 rpm, which suits duties that call for modest torque and very fast cycle frequencies. Frame size 025 and length code A keep the overall envelope short, which helps the motor fit into compact assemblies with limited clearance for adjacent components. This layout is useful in small motion modules where cable routing, mounting space, and low moving mass all affect axis response.

Closed-loop control is achieved through resolver feedback, which provides analog sine-cosine signals that the drive interpolates for precise position and velocity data. The output uses a plain shaft with a single-ended configuration, making it suitable for direct coupling to small pulleys or pinions. Because the motor is supplied without a blocking brake, any static holding function must be provided by external mechanics or by the drive itself. It is also delivered without a shaft seal, so the installation environment should remain dry and free from splash to reduce the risk of contamination near the bearing fit. This arrangement is best suited to enclosed machine spaces where the shaft connection is protected from coolant, washdown, and airborne debris.
