MDD093C-N-030-N5M-110GB0
MDD Synchronous Motors
The Bosch Rexroth Indramat MDD093C-N-030-N5M-110GB0 synchronous motor from the MDD Synchronous Motors series is designed as a high-precision drive solution for digital drive controllers. This motor for digital drive controllers delivers a nominal speed of 3000 min⁻¹ and a continuous torque at standstill of 19.5 Nm (up to 28.0 Nm with surface cooling). Featuring a robust plain shaft design and a protection category of IP 65, it excels in demanding industrial automation environments where reliability and performance are paramount.
Built with an integrated multiturn absolute encoder, the MDD093C-N-030-N5M-110GB0 ensures accurate position feedback and precise motion control. The torque constant at 20 °C is 0.61 Nm/A, reflecting efficient energy conversion. With a thermal time constant of 50 min (or 45 min during surface cooling), the motor maintains stable operation under sustained loads. The model’s centering diameter of 110 mm, motor size of 093, and motor length code C provide standardized mounting dimensions. Connection is simplified via a rugged connector interface, and standard balancing and housing ensure smooth operation.
Engineered without a blocking brake, this plain shaft motor minimizes mechanical complexity and maintenance needs. It operates reliably in ambient temperatures from 0 to +45 °C and weighs 22.0 kg, striking a balance between rigidity and compactness. The standard balancing and housing design contribute to long-term durability, while the IP65 rating protects against dust ingress and low-pressure water jets. As a purpose-built solution for industrial automation, the MDD093C-N-030-N5M-110GB0 offers exceptional compatibility, efficiency, and service life, making it ideal for precise motion applications in modern manufacturing systems.

Frequently Asked Questions
Why is the plain shaft design effective for this motor type?
It provides smooth torque transmission to connected components. This minimizes wear and supports precise coupling alignment.
How does the 0.61 Nm/A torque constant affect motor performance?
It ensures efficient torque generation per ampere. This improves energy efficiency and responsiveness under load changes.
What is the importance of a 50-minute thermal time constant?
It helps distribute heat evenly through the motor. This prevents overheating and maintains stable torque output in long-duty cycles.
How does the motor ensure low vibration levels during operation?
It uses precision rotor balancing to maintain smooth motion. This reduces mechanical oscillations and enhances component lifespan.
Why is the 110 mm centering diameter useful for installation?
It provides exact alignment between motor and driven shaft. This improves stability and reduces coupling stress during rotation.
