Product Description:

The MDD025A-N-100-N2K-040GA1 is a compact synchronous motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Intended for direct connection to digital drive controllers, it transforms precisely metered current into rapid rotary motion for pick-and-place heads, small gantries, and indexing stations. Its compact construction helps conserve installation space while still meeting aggressive cycle-time requirements in automated production cells. The motor is suited for light, high-response axes where quick acceleration and repeatable positioning are more important than large physical size. It is often selected for compact mechanisms that need smooth rotation, short move times, and consistent feedback to the connected drive.

A high nominal speed of 10000 rpm lets the rotor follow fast command sequences without excessive lag. During standstill, the electromagnetic circuit sustains 0.33 Nm of continuous torque, while a blocking brake rated at 1.0 Nm secures the load when power is removed. This combination supports axes that must hold position at rest and restart quickly when the command changes. Mounting accuracy is supported by a centering pilot of 40 mm, which keeps the housing concentric with gearboxes or couplings. Position and velocity data reach the controller through resolver feedback, carried on a keyed connector that also handles motor power. The keyed interface reduces the chance of mismatched motor and feedback wiring during installation.

Rotor and flange surfaces are balanced to the Standard grade, which helps reduce vibration at elevated speed. All electrical terminations exit on Side A, so cables can be routed from a single face of the motor. A stator-mounted integrated absolute encoder supplies multiturn position data at startup for immediate axis reference after power-up. The motor has a plain shaft with an embedded shaft seal, supporting direct press-fit couplings while protecting the bearing area. This layout keeps the connection area separate from the output end, which helps when the motor is installed in narrow machine sections.
