Critical value of electric motor air gap

System Identification and Integration Design of an Air/Electric Motor

This paper presents an integration design and implementation of an air motor and a DC servo motor which utilizes a magnetic powder brake to integrate these two motors together. The dynamic model of the air/electric hybrid system will be derived and eventually leads to successful ECE-40 driving cycle tests with a FPGA-based speed controller. The testing results obtained by using the proposed exp...

Measurement of Air Breakdown Voltage and Electric Field Using Standad Sphere Gap Method

The air gap sign.

An elderly female aspirated a donut and subsequently had loss of consciousness and cardiopulmonary arrest. Family members performed chest compressions until emergency medical services arrived and resuscitated the patient with an adequate heart rate and blood pressure. On hospital admission, the patient was nonresponsive on a mechanical ventilator. Cardiac auscultation revealed distant heart ton...

The value of compressed air energy storage with wind in transmission-constrained electric power systems

In this work, we examine the potential advantages of co-locating wind and energy storage to increase transmission utilization and decrease transmission costs. Co-location of wind and storage decreases transmission requirements, but also decreases the economic value of energy storage compared to locating energy storage at the load. This represents a tradeoff which we examine to estimate the tran...

Support Vector Machine-based Decision for Induction Motor Fault Diagnosis using Air-Gap Torque Frequency Response

In this work we propose the air-gap torque as failure signature to detect mechanical faults in particular the eccentricity. In this way, we compare the proposed signature with those most used recently in particular the current space vector (Park vector) and complex apparent power. This signature is subsequently analysed using the classical fast Fourier transform (FFT). The magnitudes of spectra...
