Product Description:

The MDD093D-N-020-N2L-110GB2 is a synchronous motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Designed for digital drive controllers, it pairs with compatible intelligent inverters to produce commanded torque and speed in automated machinery. It is intended for servo axes that require repeatable motion under closed-loop control. This motor format is well suited for enclosed machine installations where dependable operation and accurate positioning are important. It can be used on indexing, handling, and positioning applications that rely on consistent torque delivery throughout repeated operating cycles.

The motor delivers a continuous torque of 24.0 Nm at standstill, allowing it to hold moderate loads without overheating. Its rated mechanical output reaches a nominal speed of 2000 rpm. An integrated blocking brake provides up to 22 Nm of static holding force when the drive is de-energized. Accurate mechanical registration is supported by a centering diameter of 110 mm, while power and feedback connections exit on side B through a sealed connector interface. The centering shoulder helps align the motor accurately with the mating machine surface. The frame corresponds to size code 093. Standard dynamic balancing helps reduce vibration, and a shaft seal is present to limit the ingress of fine dust or coolant. The cable exit arrangement can also help keep routing organized in compact machine spaces.

The longer stack indicated by length code D increases power density without increasing the motor’s external diameter. A plain shaft interface simplifies coupling with keyed hubs or shrink discs while keeping shaft runout low. Closed-loop operation is obtained through digital servo feedback (DSF), letting the drive evaluate rotor position with fine resolution for accurate accelerations and controlled stops. This feedback arrangement also supports stable speed regulation and precise positioning during repeated start-stop cycles. The controller can respond quickly to load changes during indexing and speed transitions. This helps the motor maintain smooth motion during low-speed moves as well as higher-speed transitions.
