Abstract
The behaviour of electromagnetic braking using eddy current was studied. Started with preliminary study investigating 3 different materials of aluminium, copper and zinc to choose the best material as brake disc. It also looks on effects of increasing current induced into electromagnet. Aluminium performs better copper and zinc, and then the study continues using two different series of aluminium which are Al6061 and Al7075. A few parameters have been varied such as air-gap, brake disc thickness, number of electromagnet turns and voltage supplied to DC motor. For the purpose of recording speed (rpm) and time (s), an optical tachometer connected to PULSE analyzer has been used. Graphs presented to show the behaviour and reaction of parameters involved, including the calculation of braking torque that been generated using previous study equation. From this study, it can be concluded that Al6061 has greater performance than Al7075 as the brake disc material. It also founded that the thicker the disc, small air-gap, large number of electromagnet turns and increasing the current induced will increase the performance of this electromagnetic braking. All parameters that have been studied show significant effects to be considered in developing electromagnetic braking to replace the conventional braking system.
