Product Description:

The MDD021A-N-100-N2G-032MB0 is a compact AC synchronous servo motor manufactured by Bosch Rexroth Indramat in the MDD Synchronous Motors series. Designed for digital drive controllers, it converts commanded current into precise rotary motion for positioning axes and light-duty conveying stages in automated equipment. Its compact frame supports installations where limited mounting space and low moving mass are important. That makes it a practical choice for compact slides, feeders, and handling modules that cycle frequently.

The motor provides a continuous torque at standstill of 0.15 Nm, which is suitable for holding small loads without excessive heat buildup. It reaches a nominal speed of 10,000 rpm, which supports fast indexing cycles when paired with low-ratio mechanics. Position and velocity data are returned through resolver feedback, allowing the drive to maintain closed-loop control during acceleration and deceleration. This feedback format is commonly used where stable rotor angle information is needed across a wide speed range. All power and signal conductors exit on side B of the stator housing through a single connector, which helps keep cable routing compact in small machine spaces.

The mechanical interface uses a centering diameter of 32 mm to align the housing with mating flanges during installation. The motor is supplied without a blocking brake, so any holding function must be provided by the drive or by external machine hardware when the axis is stopped. Its output shaft uses a keyway for positive torque transmission, and the motor is delivered without a shaft seal. Because there is no shaft seal, the installation is better suited to clean, dry areas rather than locations with coolant exposure. The single-shaft layout leaves no rear shaft extension, which helps simplify coupling at the driven end and keeps the rear of the motor clear for mounting and cable access.
