A Self-Sensing Method for Electromagnetic Actuators with Hysteresis Compensation

open access: yesEnergies, 2021
Self-sensing techniques are a commonly used approach for electromagnetic actuators since they allow the removal of position sensors. Thus, costs, space requirements, and system complexity of actuation systems can be reduced.

An Exact Solution to the Modified Winding Function for Eccentric Permanent Magnet Synchronous Machines

open access: yesMathematics, 2022
The Winding Function Approach has been used since 1965 to describe the inductance behavior of small air-gap electrical machines, and several works have contributed to its formulation in the presence of mechanical faults, such as eccentricity, leading to ...

A Hybrid Control Strategy for a PMSM-Based Aircraft Cargo Door Actuator

open access: yesActuators, 2022
There are some disadvantages of a traditional AC-induced motor or hydraulic cylinder-based aircraft cargo door actuator (CDA), such as strong stopping shock, big slippage, high power, or current demand.

Smart Tendon Actuated Flexible Actuator [PDF]

open access: yesJournal of Robotics, 2015
We investigate the kinematic feasibility of a tendon-based flexible parallel platform actuator. Much of the research on tendon-driven Stewart platforms is devoted either to the completely restrained positioning mechanism (CRPM) or to one particular type of the incompletely restrained positioning mechanism (IRPM) where the external force is provided by ...

Effect of Slot Opening on Permanent Magnet Power Loss of a Permanent Magnet Synchronous Machine Driven by PWM

open access: yesEnergies, 2022
In this study, the influence of slot opening on the leakage reactance, power factors, winding current, and air gap flux density, as well as other parameters of the surface-mounted permanent magnet synchronous motor driven by an inverter is analyzed using
