Linear Electric Motors in Aircraft Technology: An Overview

Diagnosis of Mechanical Faults in Electric Motors

The ability to monitor the condition of an electrical machine has been a concern of industry for many years. Knowing when a machine requires maintenance allows users to perform the required maintenance at their convenience, rather than during costly unscheduled shutdowns. This need for improved industrial monitoring techniques has produced a number of studies on the detection of mechanical faul...

Statistical Wiener process model for vibration signals in accelerated aging processes of electric motors

This research describes random process modeling of the accelerated aging process based upon the mechanical degradation in induction motors. In order to show this aging effect, vibration measurements are considered at the end of each aging cycle, which gradually cause to bearing damage in the motor. In this manner, the accelerated aging study comprises seven aging stage sequentially and collecte...

Electrostatic Linear Inchworm Motors

We have demonstrated a family of large force and large displacement electrostatic linear inchworm motors that operate with moderate to high voltages. The inchworm motor design decouples actuator force from total travel and allows the use of electrostatic gap-closing actuators to achieve large force and large displacement while consuming low power. A typical inchworm motor measures 3 mm 1 mm 50 ...
