MDD025A-N-100-N2G-040GF0
The MDD025A-N-100-N2G-040GF0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat and belongs to the MDD Synchronous Motors series. It is engineered for integration with digital drive controllers to translate commanded current into controlled rotary motion within industrial automation. By combining compact frame dimensions with a high nominal speed, the unit is used on pick-and-place axes, electronic assembly equipment, and light spindle drives where quick acceleration and limited installation space are important.
The motor’s nominal speed reaches 10000 rpm, allowing short cycle times in light-load applications. At standstill, it can deliver 0.33 Nm of continuous torque, providing holding force for precise positioning when the axis is energized. Mechanical centering during installation is simplified by a 40 mm centering diameter, which matches standard locating recesses of compact gearboxes and mounting plates. The power and feedback connectors exit on the right side, so cable routing can be planned accordingly. Field wiring is accomplished through a connecting cable with a coupling unit, eliminating the need for fixed terminal boxes.
Because the motor is supplied without a blocking brake, any vertical or overhauling load must be secured by external means or drive torque during shutdown. A plain shaft supports use with press-fit or collet couplings and helps maintain smooth power transmission. Contaminant ingress at the shaft opening is limited by a built-in shaft seal, which helps protect internal components in environments where coolant mist or fine dust is present. Position data is returned to the controller through resolver feedback, which provides angle information across the full speed range and tolerates electrical noise. This feedback arrangement supports stable closed-loop control as the axis accelerates toward its rated velocity.
