MDD025A-N-100-N2K-040PB1
MDD Synchronous Motors
The Bosch Rexroth Indramat MDD025A-N-100-N2K-040PB1 from the MDD Synchronous Motors series is a precision-engineered Motor for digital drive controllers designed to deliver reliable performance in demanding automation environments. This Motor Size 025 unit features a compact Motor Length Code A housing, making it ideal for installations with limited space. It integrates an Integrated absolute encoder and offers Resolver feedback for high-accuracy position and speed monitoring. With its standard Standard balancing and robust construction, this motor ensures smooth operation across its entire speed range.
Equipped with a With blocking brake holding brake providing 1.0 Nm of Holding Brake Torque, the MDD025A-N-100-N2K-040PB1 maintains precise shaft locking under load. At standstill, it delivers a Continuous Torque at Standstill 0.33 Nm, which guarantees stable holding capacity during power interruptions. The motor spins up to a Nominal Speed 10000 min⁻¹ while the With shaft seal shaft seal protects the interior from contaminants. The Keyway shaft type and 40 mm Centering Diameter ensure straightforward coupling to gearboxes and machinery spindles, while the standard housing maintains durability in industrial settings.
Connection is streamlined via a side-mounted Connector interface with a Connection Direction Side B orientation, facilitating tidy wiring runs in control cabinets. The motor’s Housing Standard design integrates seamlessly with Rexroth’s drive controllers, and its Shaft End Standard (without side B shaft end) ensures compatibility with a wide range of couplings and accessories. With both absolute encoder and resolver feedback onboard, this motor offers versatile feedback options, delivering tight control loops for precision motion applications.

Frequently Asked Questions
What practical considerations arise from using the blocking/holding brake (1.0 Nm) in dynamic applications?
The brake adds damping at standstill and holds position under load when power is off or faulted; in dynamic cycling, the brake increases response time slightly when engaging/disengaging and adds weight/mass. Also, brake wear should be monitored in frequent start/stop operations, and control strategy must account for brake release time before motion starts.
What does “standard balancing” imply in terms of vibration and permissible radial loads at high speed?
Standard balancing means the rotor is balanced to a factory tolerance suited for normal operational speeds; beyond certain RPMs or under heavy radial loads, vibration may increase. If application demands ultra‐low vibration (e.g. spindle usage), selecting “high balancing” or customizing balance may be needed to reduce bearing loads and noise.
With shaft seal included, what level of protection does this motor have against dust, particulates, or fluids?
A shaft seal helps protect the internal encoder and bearing from contaminants in environments with dust or light fluid exposure, improving uptime. However, it doesn’t guarantee full ingress protection (like IP‐rated enclosures)—sealed environments still need proper enclosures if exposure is severe.
How does the “Motor Size 025, Length Code A housing” affect mounting options and mechanical stiffness?
Size 025 with Length Code A gives a relatively compact envelope, which helps where space is constrained, but may trade off some moment of inertia and stiffness compared to longer housings. For high dynamic loads or those requiring resistance to external torque, ensuring the mounting is rigid and aligned minimizes deflection and vibration.
How does the motor’s continuous torque at standstill (0.33 Nm) affect its ability to hold loads during power loss?
At standstill this torque defines how much load the motor can resist without moving; 0.33 Nm means modest holding capacity, suitable for light holding tasks but often needing a brake if heavier loads are involved. In applications where the load or inertia is greater, the holding brake (1.0 Nm in this unit) becomes essential to prevent creep or drift.
