Product Description:

Bosch Rexroth Indramat manufactures the MDD025A-N-100-N2G-040GB1, a member of the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts commanded current into precise rotary motion for pick-and-place arms, labeling heads, and other rapid-cycle axes in automated lines where quick acceleration and accurate stopping are required. The standard housing supports compact integration with miniature gearheads or direct-drive couplings, while the integrated blocking brake holds the load when power is removed and helps prevent unintended axis movement at standstill.

Its continuous stall torque is 0.33 Nm, which is the steady mechanical load the axis can hold without overheating while motionless. During operation, the rotor can reach a nominal speed of 10,000 rpm, so position loops can run at high update rates and the motor can support fast transfer or indexing moves. When the brake is engaged, up to 1.0 Nm of holding torque resists back-driving forces. Electrical and feedback cabling exit on side B of the frame, which can simplify routing when drives are mounted in rows or when space is limited near the machine interface. A centering shoulder diameter of 40 mm aligns the motor concentrically to the machine flange, and the plug-in connector supports straightforward installation.

Feedback is provided by resolver feedback, which supplies high-resolution rotor angle data and tolerates electrical noise better than incremental encoders for stable closed-loop control. The motor uses a plain shaft rather than a keyed output, which helps minimize coupling runout in compact drive arrangements. The front face is built with a shaft seal, which helps limit contaminant ingress at the bearing during routine machine operation. Standard balancing helps keep vibration low during operation. The motor uses the compact 025 frame with length code A, and it has a shaft end only on the drive side to suit tight spaces.
