Abstract

This report is about designing a slot-less linear actuator for food processing application. Linear actuator is a device that produces linear motion without using any mechanical transmission to converts rotary motion into linear motion. The objective of this research is to design slot-less linear actuator for food processing application. People are still using traditional or conventional compression method by pressing hand in the moulding device. Samperit and tart cookies are examples of the food that requires this method to process it. But nowadays, this method is no longer practical as this method is not productive in handling large amount of dough. It takes a long time to press the dough as it requires human energy. So, a power moulding device embedded with slot-less linear actuator is proposed to help increasing the productivity as it use electrical as a source of force. The process flow for this project is firstly, to carry out preliminary experimentation using traditional moulding device to get the real dimensions and specifications of the moulding device. Then, the slot-less linear actuator has been designed using SolidWorks software and the modeling by using Ansys Maxwell software. There are two (2) models have been design; the model using one (1) coil and the model using two (2) coil. Next, the analysis of the coil sizing has been done. The analysis of the coil sizing includes the number of coil, the height of the coil and the varied gap of the two (2) coils. The result gain should fulfill the target design specifications and the expected thrust characteristic. Lastly, the best model of the slot-less linear actuator is chosen and the model is fabricated using rapid prototyping.
