AIR GAP MONITORING

Air gap sensors are strategically positioned on the stator windings to monitor the rotor-stator gap, providing real-time data for maintaining machine efficiency.

Description

Air gap monitoring is essential for ensuring the optimal operation and longevity of large, low-speed hydro generators, motors, and other rotating machinery. It involves real-time measurement of the distance between rotor poles and the stator, which helps maintain machine balance and efficiency, preventing mechanical issues and improving performance.

Benefits and Issues Addressed

MC-monitoring's Air Gap Transducers offer significant benefits by enhancing the reliability and efficiency of rotating machinery. These sensors provide precise, real-time monitoring to prevent unexpected downtime and costly repairs, enabling operators to maintain optimal machine performance, detect potential issues early, and schedule maintenance proactively.

Rotor-Stator Contact: Prevents damage by providing early warnings if the gap becomes too narrow.
Uneven Rotor Wear: Identifies wear patterns early to address issues before they escalate.
Magnetic Field Disturbances: Ensures accurate measurements in environments with strong magnetic interference.
Thermal Expansion: Manages thermal expansion effects with active temperature compensation.
Inconsistent Maintenance Intervals: Enables condition-based maintenance to optimize intervals and reduce unexpected failures.

Monitoring Parameters

MC-monitoring’s air gap transducers measure two key parameters:

MinGap: Indicates the minimum gap distance, providing crucial data to avoid rotor-stator contact.
Pole Profile: Represents the profile of the rotor poles, helping to assess the shape and uniformity of the poles.
