Product Description:

The MDD025A-N-100-N2K-040GF0 is a compact synchronous motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for integration with digital drive controllers, the unit converts electrical energy into tightly regulated mechanical rotation. This supports pick-and-place heads, laboratory centrifuges, and other equipment that need rapid acceleration and position accuracy in limited installation spaces. Its compact format also suits small axes where available mounting room is restricted.

Mounting is guided by a centering boss diameter of 40 mm, allowing the flange to align precisely with gearbox or frame surfaces and maintain the standard balancing quality noted for this model. At standstill, the motor can supply 0.33 Nm of continuous torque, which lets holding circuits maintain load position without overheating the windings. Once energized, the rotor can operate steadily at a nominal speed of 10,000 rpm, a value that supports high-cycle production where short move times are critical. Position information is generated by an integrated absolute encoder, so the control system receives an unambiguous shaft angle immediately after power-up. Power and feedback signals are routed through a connecting cable with coupling unit, and the plug-in interface avoids the need to open sealed terminal chambers.

The motor has size 025 with length code A, describing a short stator body that keeps mass low and inertia minimal for dynamic servo duties. All electrical terminations exit on the right side, which can shorten cable runs in cabinets laid out for right-hand routing and keep the wiring path direct. A plain shaft is fitted with a tight shaft seal, and the design ships without a blocking brake, so external mechanical restraints or drive torque must hold the load when power is removed. The motor also has a standard housing and a standard shaft end, which keep the mechanical interface conventional for this frame.
