8 but only when turning slowly. Molecular motors are not heat engines. If the energy available from the hydrolysis of ATP were uniformly distributed throughout the F 1-ATPase, it would heat up by less than 0.1 ᑻC and then cool off with a decay time of less than 0.1 ns. The energy available from the binding of ATP or the release of inorganic phosphate (or whatever) must be stored in springs (con...

Effective condition monitoring of induction motors requires knowledge of the number of rotor slots and the rotor speed. These were primarily obtained in the literature by multiple measurements and using design knowledge of the motor under test. Furthermore, the earlier studies have mainly concentrated on stator current analysis. This paper investigates the use of the stator current, axial flux,...

Hover performance of a twin-rotor test model in terms of rotor overlap sweep, blade collective pitch, and blade tip speedwasexaminedexperimentally.The experimental setup consisted of two three-bladed rotors (tandem rotor configuration) with a diameter of1,220 mm and constant chord of 38 mm, giving a blade aspect ratio of 16.05. The blades were of a rectangular planform with NACA 0012 cross-sect...

The model for the stator-rotor interaction is discussed in the sections The stator-rotor interaction and The rotor switching dynamics of the main text. The model is based on the model Oster and Blair and coworkers [1, 2] and Meacci and Tu [3], but extended to include the conformational transitions of the rotor protein complex. Here, we discuss aspects of the model that are not discussed in the ...

This paper is the first of a three part report on the transient thermal analysis of screw compressors. Knowledge of rotor-to-housing and rotor-to-rotor clearances is a fundamental first step in defining part dimensions that lead to a design with high efficiency and reliability, characteristics which must be balanced as they impose opposite demands on internal clearances. As reliability and perf...
