| description |
In recent years, researcher has developed many actuators with different configurations
depending on application required. Linear actuator has become one of the most popular
actuator used in industry especially in factory automation. Linear motor, which have a
compact and simple structure are easy to control compare to rotational motor [1]. The
advantages of linear actuator are small size, low power and high thrust. The thrust of
linear motor can be applied on to the load without any mechanical loss as rotation motor.
But then, the generation of thrust produced by linear actuators is barely being fully
investigated. Therefore, problem arises in producing low cost machine but with higher
thrust production.
A study was conducted with the objective to investigate thrust density characteristics in
relation with dimension. Two designs were tested, that is Linear DC actuator using
electromagnetic application and Linear DC actuator which using permanent magnet application. The range of current supplied to wound coil is 1 A to 3 A, while permanent
magnet produced magnetic flux directly.
Expressions on the thrust generation on both linear actuators were derived in relation
with the dimension and size of the machine. Derivation was done based on a few
assumptions that may constitute to the objectives of this study. For clarification
purposes, experiment on both linear actuators was done depending on the physical
condition. Through the experimental result, comparison can be made between theoretical
and experimental result in order to find the thrust density characteristic of linear
actuator.
Basically, the objective of this study is achieved when comparison that has been made
for both type of linear actuator shows the largest error was only 20%. For future
improvement, a few prototype of linear actuator with different configuration of closed
loop path for the flux to flow can be made. This study only concentrated on the same
closed loop path of flux flows with a few assumption have to be taken which are the
temperature and type of material for yoke is neglected. It is important to take the a few
assumptions in order to focus on the thrust density characteristics in relation with the
dimension. |
