Simulation of Dynamics of a Permanent Magnet Linear Actuator
Comparison of two approaches for the simulation of the dynamic behaviour of a permanent magnet linear actuator is presented. These are full coupled model, where the electromagnetic field, electric circuit and mechanical motion problems are solved simultaneously, and decoupled model, where first a set of static magnetic filed analysis is carried out and then the electric circuit and mechanical m...
متن کاملEvaluation of Various Permanent Magnet Arrangements on Linear Actuator
Linear actuator are used to provide linear motion in the absence of a motion translator. By using the linear actuator, the linear motion can be produce with high degree of efficiency. Linear actuators can be designed with and without slots; moreover, there are various types of magnetization arrangements can be applied to the mover. In this paper, ten different magnetization arrangements were us...
متن کاملFinite Element Analysis of Permanent Magnet Synchronous Motors Subjected to Symmetrical Voltage Sags
This paper studies the effects of symmetrical voltage sags on the operational characteristics of a Permanent Magnet Synchronous Motor (PMSM) by Finite Element Method (FEM). Voltage sags may cause high torque pulsations which can damage the shaft or equipment connected to the motor. By recognizing the critical voltage sags, sags that produce hazardous torque variations could be prevented. Simula...
متن کاملModeling and Precision Control of Permanent Magnet Linear Motors
Abstract: Permanent magnetic linear motors(PMLMs) are easier to accelerate and achieve higher precision than rotary motors. Hence, they have a broad range of applications in the manufacturing industry and other motion control fields. Owing to the structural variation, however, the models of permanent magnet linear motors and rotary motors are different. As a result, their motion control systems...
متن کاملDynamic Characteristics of a Bistable Linear Actuator with Moving Permanent Magnet
The dynamic characteristics of an axisymmetrical linear actuator with axially magnetized moving permanent magnet are obtained using combined field and circuit approach. The magnetic field of the actuator has been analysed using the finite element method over a current-displacement sampling grid. Two field analyses are carried out for each point of the grid one for the real system and one for th...
