Product Description:

The MDD025C-N-100-N2G-040FD0 is a compact permanent-magnet synchronous motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Designed as a drive element for digital controllers, the unit converts commanded current into rotary motion for small indexing tables, pick-and-place modules, or spindle axes in automated equipment. Its mechanical outline follows the 025 frame with length code C, giving a narrow body that fits high-density multi-axis assemblies while keeping inertia low for rapid acceleration.

Mechanical mounting features support accurate alignment and straightforward cabling. A centering diameter of 40 mm matches standard flange bores, and the power and feedback leads exit on Side B so wiring can stay inside the cabinet sidewall. The motor ships with a connecting cable with coupling unit, eliminating separate plug procurement. During continuous stall the rotor supplies 0.90 Nm of torque, adequate for lightweight tooling that nevertheless requires closed-loop holding force. Because it is delivered without a blocking brake, any static locking must be provided by the drive or external mechanics; the omission reduces mass and service parts.

Position information is generated by resolver feedback, enabling sinusoidal commutation and immunity to electrical noise. Under rated excitation the motor reaches a speed ceiling of 10000 min⁻¹, supporting high-throughput cycles where short process times are critical. The rotor uses a plain shaft profile, making it compatible with press-fit couplings or collet grips, and it is supplied without a shaft seal, so the installation area must be free from liquid coolant or airborne oil. Standard dynamic balancing limits vibration that could otherwise transfer to adjacent precision devices.
