Optical Torque Exerted Rotator Illumination Vortex Beam
2013/7/3
We investigate the torque on a specially shaped rotator produced by a vortex beam. The formulas for the torque alongx, yandzdirections are derived, and numerically calculation is performed. It is foun...
Low cogging torque and high efficient 3-phase spindle motors by reshaping magnetic circuit profiles
2011/11/29
The dynamic characteristics of a 3-phase spindle motor with 12-poles and 9-slots can be improved by reshaping the magnetic circuit profiles. The stator cores were designed with different ratios of x/y...

The belt conveyor is the main transport equipments in coal field, and its controllable drive system directly impacts on the running safety reliability and cost in coal production. Starting speed is un...
Coupling between switching regulation and torque generation in bacterial flagellar motor
Supramolecular assembly switching regulation and torque generation bacterial flagellar motor
2011/8/26
The bacterial flagellar motor plays a crucial role in both bacterial locomotion and chemotaxis. Recent experiments reveal that the switching dynamics of the motor depends on the motor rotation speed, ...
Determination of the Upper Critical Field of a Single Crystal LiFeAs: The Magnetic Torque Study up to 35 Tesla
iron-based superconductor LiFeAs upper critical field anisotropy
2010/11/18
We report on the upper critical field Bc2 of a superconducting LiFeAs single crystal with
Tc ∼16K, determined from magnetic torque measurements in dc-magnetic fields up to 35T and
at temperatu...
Spin Torque Ferromagnetic Resonance Induced by the Spin Hall Effect
Spin Torque Ferromagnetic Resonance Spin Hall Effect
2010/11/22
We demonstrate that the spin Hall effect in a thin film with strong spin-orbit scattering
can excite magnetic precession in an adjacent ferromagnetic film. The flow of alternating current through a P...
Van der Waals torque induced by external magnetic fields
torque induced external magnetic fields
2010/11/8
We present a method for inducing and controlling van der Waals torques between two parallel slabs using a constant magnetic field. The torque is calculated using the Barash theory of dispersive torque...
