MDD025C-N-100-N2K-040PD0
The MDD025C-N-100-N2K-040PD0 is a compact servo unit produced by Bosch Rexroth Indramat and included in the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it delivers direct rotary actuation for positioning axes, packaging stations, and light pick-and-place modules. When paired with Indramat drive electronics, the unit converts commanded current into proportional torque and speed, making it suitable for compact automated systems that require accurate rotary motion.
Its continuous torque at standstill is 0.90 Nm, so the shaft can hold loads without overheating when the axis is clamped. The nominal speed reaches 10,000 rpm, which supports high throughput where rapid indexing is required. Mechanical alignment is provided by a centering diameter of 40 mm, which positions the motor flange accurately on the machine frame. Cabling exits on Side B, and power plus feedback are routed through a connecting cable with a coupling unit, simplifying plug-in installation. Size code 025 and length code C create a short rotor stack that minimizes inertia, while the keyway shaft and shaft seal support torque transfer and help block coolant or dust from migrating along the shaft.
The rotor uses standard balancing, and the sealed-frame housing matches the series mounting geometry while keeping the external form compact. Position data comes from an integrated absolute encoder, and the drive uses resolver feedback to close the loop without external sensors. For applications that rely on mechanical holding devices, the motor is supplied without a blocking brake, so any static load must be secured by the controller or by an external clamp. The motor has a single shaft end on Side A and no shaft end on Side B, which conserves axial space inside compact stages while still providing a keyway for couplings.
