MDD021B-N-100-N2G-032MA0
The MDD021B-N-100-N2G-032MA0 is a small synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts drive commands into high-speed rotary motion for light-duty axes in assembly, laboratory, or packaging equipment. In automated systems, it supports closed-loop velocity and position control so coordinated moves remain accurate during rapid starts, stops, and short indexing cycles. Its compact format also makes it suitable for machines where installation space is limited and low moving mass is important.
At the mechanical interface, a centering diameter of 32 mm seats the flange accurately, while standard balancing helps reduce vibration transfer into fine tooling. When the rotor is locked, the windings deliver a continuous torque of 0.30 Nm, which supports stable holding force during precise positioning tasks. The shaft reaches a nominal speed of 10,000 rpm, fitting fast cycle requirements in compact handling equipment. All power and feedback conductors exit on Side A through a single circular connector, which keeps cable routing on one side of the machine and helps in tight layouts. The B length gives the motor a short stator stack that fits shallow frames without adding unnecessary axial depth.
Resolver feedback provides rotor angle information at zero speed, allowing stable current control without an added feedback device. The output shaft uses a keyway for positive torque transmission and is supplied without a shaft seal, which suits clean, dry enclosures where contamination control is handled by the surrounding machine design. The motor is supplied without a blocking brake, so holding force must come from the drive or from external mechanical restraint. A single drive-side shaft end leaves the rear side clear, which can help where nearby components limit clearance. Its frame size of 021 keeps the footprint suitable for lightweight pick-and-place axes and other rapidly cycled motion systems.
