MDD025C-N-100-N2G-040FD1
The MDD025C-N-100-N2G-040FD1 synchronous motor is produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for digital drive controllers, it converts electrical power into controlled mechanical rotation for compact automation stages, indexing tables, and miniature gantries. Its short housing lowers inertia and eases integration into tight machine frames. This layout suits applications that need quick acceleration and precise speed control in a small mounting space. Standard balancing helps the motor deliver repeatable motion while keeping vibration low in high-cycle production tasks.
The motor develops a continuous standstill torque of 0.90 Nm, enabling constant force delivery for static positioning without thermal overload. During operation, it can reach a nominal speed of 10,000 rpm, which suits rapid-response spindles and fast pick-and-place movement. Mechanical centering is handled by a 40 mm centering diameter, which aligns the flange with gearheads or mounting plates. All power and feedback conductors exit on side B, and the motor uses a connecting cable with a coupling unit for the electrical interface. Position data are captured by resolver feedback, providing analog sine-cosine signals with good resistance to electrical noise. The motor has a 025 frame size, which supports installation where space is limited.
For holding functions, the motor includes a blocking brake that supplies 1.0 Nm of static torque, letting vertical axes stay fixed when drive power is off. The rotary output is provided by a plain shaft, and the shaft end is present only on the drive side, leaving the opposite face free for electrical connections. Because the unit is delivered without a shaft seal, it should be mounted inside clean enclosures where fluid ingress is not expected. This shaft arrangement supports direct coupling to pulleys or flexible couplings without extra machining. It can also be used in dry, enclosed machine sections where exposed fluids are not part of normal operation.
