MDD025A-N-100-N2G-040GR0
The MDD025A-N-100-N2G-040GR0 is a synchronous servo motor engineered by Bosch Rexroth Indramat for use with digital drive controllers in the MDD Synchronous Motors series. As a compact rotating actuator, the unit converts commanded electrical energy into mechanical torque and speed for positioning tasks inside pick-and-place heads, small indexing tables, and labeling machinery where rapid motion cycles are required. Its compact format suits machinery that needs precise motion in limited installation space. When paired with a compatible controller, it supports closed-loop operation for repeatable starts, stops, and speed changes during automated movement.
Mechanically, the motor belongs to size 025 with length code A, so the active stack remains short and light while still providing a continuous standstill torque of 0.33 Nm. Dynamic axes benefit from its nominal speed of 10000 rpm, which supports fast positioning in short cycles. Balancing is performed to the standard grade, which helps limit residual vibration across the working range. Electrical and signal leads exit on the right side through a keyed connector, reducing cable loops inside tight machine frames. Position and velocity data are relayed by resolver feedback, which provides analog sinusoidal signals that are resistant to electrical noise and suitable for high rotational speeds.
A centering register of 40 mm aligns the flange to gearboxes or mounting plates, helping the motor seat accurately during installation. The output uses a plain shaft with a shaft seal arrangement to help keep lubricants in and contaminants out. The unit is supplied without a blocking brake, so holding torque must be furnished by the drive or by external mechanics when the axis is at rest. Standard housing construction resists typical shop dust, and the shaft end is provided only on the drive side to avoid added overhung mass on side B. This layout supports stable operation where compact dimensions and high rotational speed are both required.
