MDD025A-N-100-N2K-040GR0
The MDD025A-N-100-N2K-040GR0 synchronous motor is built by Bosch Rexroth Indramat and belongs to the MDD Synchronous Motors series. It is specified as a motor for digital drive controllers, meaning it pairs directly with Rexroth servo amplifiers to deliver commanded motion on compact machine axes. Integrated feedback reports rotor position to the drive, supporting precise motion control and short cycle times on fast axes. The A-length, size-025 housing keeps total mass low, making the unit suitable for high-speed pick-and-place heads, small indexing tables, and other automation tasks that require rapid acceleration but only moderate torque.
At the mechanical interface, the centering pilot ring is 40 mm in diameter, allowing precise flange alignment with gear stages or fixtures. The rotor can provide a continuous standstill torque of 0.33 Nm, enough to hold or increment light loads without overheating. Designed for high throughput, the winding reaches a nominal speed of 10000 rpm, so the connected drive can execute frequent start-stop sequences without exceeding base frequency limits. All power and feedback lines exit on the right side of the housing and are terminated through a keyed connector. Standard dynamic balancing minimizes residual vibration during extended high-speed operation, helping preserve bearing life and maintain feedback accuracy.
Position data is returned through absolute encoder feedback, so rotor position is available without a homing cycle after power-up. A plain shaft mates directly with miniature pulleys or couplings, and operation is protected by a fitted shaft seal that limits grease migration into the stator air gap. Because the motor is supplied without a blocking brake, any power-off holding requirement must be met by the drive or an external clamp. The standard housing, A-length body, and single-ended shaft arrangement create a compact package that integrates easily into multi-axis gantries and laboratory automation frames without adding excess inertia.
