Product Description:

The MDD025A-N-100-N2K-040GA0 is a compact servo motor produced by Bosch Rexroth Indramat and belongs to the MDD Synchronous Motors series. It is intended for use with digital drive controllers, where it converts commanded current into high-speed rotary motion for positioning axes and light handling devices in industrial automation. Its compact size helps it fit installations where available space is limited, and its integrated feedback arrangement supports closed-loop operation during speed and position control. The housing remains mechanically compatible with standardized mounting hardware, which helps the motor fit small axis layouts without requiring a larger frame.

Its continuous stall torque is 0.33 Nm, which is the steady torque the motor can deliver while the shaft is stationary under proper thermal conditions. A centering pilot of 40 mm helps align the motor accurately on the machine interface and supports consistent shaft positioning. The rotor is balanced to the standard grade, so extra balancing disks are not required for normal installation. The motor is rated for a nominal speed of 10,000 rpm, making it suitable for applications that require high rotational velocity from a small frame. Power and feedback conductors exit on Side A through a single connector, which helps simplify cable routing in compact cabinets.

The feedback system combines an integrated absolute encoder with resolver feedback, so the drive receives position information and analog feedback signals for closed-loop control. The encoder arrangement supplies single-turn position data, and the analog feedback path supports stable velocity estimation during operation. The output uses a plain shaft fitted with a shaft seal, allowing connection to standard couplings while helping keep contaminants away from internal parts. The motor is supplied without a blocking brake, so holding force must be provided by drive torque or external mechanics when the axis is stopped. It is built in length code A with a 025 frame housing and has no side-B shaft end, which keeps the mechanical layout simple.
