Design and Modelling of a Novel Linear Electromagnetic Actuator
IFAC Proceedings Volumes, 2004Abstract The paper presents the design of a novel permanent magnet linear actuator for short-stroke and high dynamic operations. The design procedure based on the magnetic analysis is shown and finite-element calculation results are given. In the second part the modelling of the developed actuator for dynamic and control studies is presented, where a

Nonlinear electromagnetic force analysis and compensation control of electromagnetic linear actuator
Physica Scripta, 2023Abstract Nonlinear electromagnetic force is a common phenomenon in electromagnetic linear actuators (EMLA). This nonlinearity limits the application in high-precision control systems. For facilitating the controller design, the influencing factors of nonlinear electromagnetic force were analyzed, and the quadratic polynomial with unknown

Electromagnetic Modeling of a Novel Linear Oscillating Actuator
IEEE Transactions on Magnetics, 2008Single-phase linear oscillating actuators (LOAs) produce short-stroke reciprocating motion, and, thus, have many applications. Feasible pole/tooth number combinations for single-phase tubular moving-magnet LOAs are identified and results from a study on a 2-pole LOA equipped with an E-cored stator, and quasi-Halbach magnetized and radially magnetized ...

A New Electromagnetic Linear Actuator for Quick Latching
2006 12th Biennial IEEE Conference on Electromagnetic Field Computation, 2006The traditional engine valve train in a combustion engine is the mechanically driven camshaft system that provides one-fixed valve timing. The variable valve timing (VVT), however, is highly required to achieve the significant improvement in fuel economy and lower emission.

Robust Design of Quadratic Electromagnetic Linear Actuator
Advanced Materials Research, 2012This paper describes the robust design of the Quadratic linear actuator. The linear actuator is higher efficiency than the existing rotary or reciprocating actuator. The linear actuator, however, has the inherent drawback of air gap variation because its linear motion is usually guided by springs and its dynamic performance is difficult to maintain ...

Sensorless position control of electromagnetic linear actuator
Proceedings of the 21st IEEE Instrumentation and Measurement Technology Conference (IEEE Cat. No.04CH37510), 2004Sensorless principles utilize the transducer characteristics of actuators during excitation. As the measured data are extracted directly from the actuator, an additional sensor is not required. The information on the armature position of a solenoid can be found in its impedance.
