Product Description:

The MDD093D-N-040-N2L-130GL1 servo unit is manufactured by Bosch Rexroth Indramat and belongs to the MDD Synchronous Motors series. Designed for use with digital drive controllers, this permanent-magnet synchronous motor converts commanded current into regulated torque and speed for tool changers, gantries, and packaging axes. Its role is to turn electrical commands into repeatable rotary motion so positioning loops remain accurate under changing mechanical loads. This arrangement lets the paired controller correct speed and position errors during repeated starts, stops, and reversals in coordinated multi-axis machinery.

At standstill, the motor supplies 24.0 Nm of continuous torque, supporting demanding low-speed operation without external gearing. Under rated excitation, the rotor reaches 4000 rpm, giving the axis a broad speed range for indexing and transfer tasks. A centering diameter of 130 mm helps align the motor with the machine flange, and standard dynamic balancing helps limit vibration at operating speed. Position data are transmitted through digital servo feedback (DSF), allowing the drive to maintain precise closed-loop control. Power and feedback connectors exit on the left side, which can simplify cable routing where motors are mounted close together. The unit also uses a plug connector, has a cast-aluminum housing, and includes a shaft seal to help keep dust or coolant mist away from the bearing area.

A blocking brake delivers 11 Nm of static torque when power is removed, helping secure loads during stopping or power-off conditions. Motion is transferred by a plain shaft, allowing couplings to clamp directly without a keyway. Frame size 093 sets the mounting pattern, while length code D indicates a longer lamination stack that supports greater thermal mass during short overload periods. The shaft is provided on side A only, which helps limit overall length, and the internal wiring remains enclosed within the sealed housing for a cleaner exterior layout. This layout suits compact axis assemblies where brake holding, direct coupling, and protected internal cabling are all useful in daily operation.
