MDD Synchronous Motors
MDD025A-N-100-N2G-040FA1, Bosch Rexroth Indramat, MDD Synchronous Motors owns a precision digital AC servo design optimized for high-performance motion control. This Motor for digital drive controllers features a permanent-magnet rotor with integrated resolver for commutation and rotor position sensing. The motor delivers a Nominal Speed of 10000 min⁻¹ and employs a Plain shaft output for straightforward coupling. Its compact frame and standard housing allow for seamless integration into existing Indramat drive systems.
Engineered for reliability, the motor balances performance with rugged durability. It offers Continuous Torque at Standstill of 0.33 Nm and a Holding Brake Torque of 1.0 Nm, thanks to a built-in blocking brake that secures loads safely when de-energized. The Centering Diameter of 40 mm and Motor Length Code A define a streamlined footprint, while the Rotor Balance standard ensures minimal vibration. A Resolver feedback system guarantees precise speed and position control, and the IP rating—featuring a standard shaft seal configuration—keeps contaminants at bay. Connections are made via a side-mounted Connector on Connection Direction A for easy wiring.
Installation and commissioning benefit from the MDD series’ drop-in compatibility with Indramat digital drive controllers, eliminating the need for custom mounting hardware. The robust standard housing and absence of side B shaft end simplify mechanical integration and maintenance. Users deploying this motor in robotics, conveyor systems, or CNC applications will appreciate its reliable braking, compact size, and precise feedback for smooth, jitter-free motion.

Frequently Asked Questions
What implications does the 40 mm centering diameter have for motor mounting and alignment?
A 40 mm centering diameter ensures compatibility with standard flanges and alignment bushings, reducing mechanical misalignment errors. It also simplifies installation in systems designed for “025” frame sizes by matching common interface dimensions.
What does “continuous torque at standstill = 0.33 Nm” mean in terms of thermal limits and duty cycles?
Delivering 0.33 Nm continuously at zero speed implies the motor must sustain that torque without cooling airflow, so thermal buildup (winding, rotor losses) will be a limiting factor. For high duty cycles at or near standstill, thermal time constants and ambient temperature must be considered to avoid overheating.
How does the plain shaft (no side-B extension) impact coupling options and dynamic balancing?
A plain shaft simplifies couplings (flexible, rigid) but may restrict mounting of accessories (encoders, gearboxes) that require axial clearance on the shaft end. Also balancing is standard; if you add heavy attachments, you may need dynamic balancing to avoid vibration at high speeds.
What role does motor size code “025” play in determining inertia, torque constant, and dynamic response?
Motor size “025” implies a relatively small rotor and stator assembly, which gives lower rotor inertia and therefore quicker acceleration and deceleration. However, lower inertia often means less peak torque before saturation or drive current limits; matching drive current capability to motor’s torque constant is critical.
What trade-offs are there between having a holding brake (blocking/unblocking) vs. omitting it in applications using the MDD025A-series?.
Adding a holding brake adds torque capacity for stationary hold (useful in vertical axes or safety locks), but increases motor mass, adds braking delay, increases wiring/maintenance. Omitting the brake simplifies the design, reduces cost and inertia, but requires alternative locking or safe-stop strategies
