Frequently Asked Questions

What advantage does the digital servo feedback (DSF) in the MDD090C-N-030-R2L-110PB0 motor provide?

The DSF system enables closed-loop monitoring of rotor position and speed, enhancing precision and repeatability. This means tighter control for high-accuracy applications and reduced drift over time

How does the keyway shaft type in the MDD090C-N-030-R2L-110PB0 motor influence torque transmission?

The keyway shaft provides a positive mechanical drive connection that resists torsional slip, delivering reliable transfer of the rated 10.4 Nm continuous torque. This is especially valuable in dynamic start-stop or high-acceleration scenarios.

What role does the motor’s nominal speed of 3000 min⁻¹ play in system selection?

A nominal speed of 3000 min⁻¹ defines the designed continuous rotational speed under rated load and cooling conditions, guiding gearbox ratio and system dynamics. Matching this speed supports optimal performance and lifespan.

What mechanical interface benefits are offered by this motor in modular machine design?

The motor’s 090 frame size, length code C, and standardized centering diameter offer drop-in compatibility with existing machines, reducing build time and streamlining maintenance. The configuration fosters machine standardisation and easier spares management.

How does the standard housing design of the motor impact installation and cooling?

The standard housing supports natural convection and surface cooling, simplifying thermal management without requiring external fans. This eases installation in compact machine frames while maintaining reliability.
