Product Description:

The MDD025C-N-100-N2K-040MC1 synchronous motor is manufactured by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Designed for digital drive controllers, it converts electrical energy into precise rotary motion for compact machine axes, pick-and-place heads, and other automation positions that demand fast speed regulation and repeatable positioning.

This unit delivers a nominal shaft speed of 10000 min⁻¹, enabling high-cycle positioning where short move times are critical. At standstill it supplies 0.90 Nm of continuous torque, and when the blocking brake is engaged it resists back-drive with 1.0 Nm of holding torque, safeguarding vertical or safety-related loads during power removal. Position data is captured by the integrated absolute encoder and transmitted through resolver feedback, so the controller always knows rotor angle after a restart. Mounting relies on a centering diameter of 40 mm, and all power and signal conductors exit the housing on Side A, simplifying cabinet layout when several axes share one machine wall.

Mechanical interface details suit small-footprint machinery. The single-ended shaft is ground with a keyway for positive torque transfer, and the frame corresponds to size 025 with length code C, allowing interchangeability with other units of the same envelope. Dynamic balance remains at the standard grade to limit vibration, and the housing is the standard finned style for forced-air cooling inside a cabinet. Power reaches the stator through a connecting cable equipped with a coupling unit, easing quick exchange during service. The output end is supplied without a shaft seal, acceptable for dry, particulate-free installations where an external seal is unnecessary.
