Product Description:

The MDD025A-N-100-N2K-040ME0 is a compact synchronous servo motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Designed for digital drive controllers, it supplies high-speed rotary motion to axes that need precise velocity and position regulation in automated machinery. It converts electrical power from the drive into controlled mechanical torque for small pick-and-place heads, auxiliary spindles, and other light-duty tooling in tightly integrated production cells. That makes it suitable for responsive motion tasks where quick speed changes are more important than high torque output.

The motor provides a continuous standstill torque of 0.33 Nm, allowing an axis to hold load at zero speed without excessive heating. Driven by an appropriate inverter, the rotor reaches a nominal speed of 10,000 rpm, which supports rapid indexing and short duty cycles. Mechanical location uses a centering diameter of 40 mm, while size code 025 and length code A keep overall mass low. Torque is transmitted through a shaft with a keyway, and the opposite end has no shaft extension. No shaft seal is fitted, so the motor should be used where coolant and heavy dust are kept away from the shaft area. Position data for commutation and absolute reference is supplied by an integrated absolute encoder. All power and feedback leads exit to the left, matching the specified connection direction.

Rotor components are finished to Standard balancing quality, which helps limit vibration during normal industrial operation. The drive can also use a secondary channel that returns resolver feedback for motor feedback processing. The motor is supplied without a blocking brake, so any power-off holding function must be provided externally when the application requires it. The electrical interface uses a connecting cable with coupling unit, which allows the motor to be connected and disconnected without hardwiring the leads directly into the housing. The standard housing keeps the familiar mounting geometry used across the series.
