Thermal analysis on BLDC Motors is very important to be learned in order to obtain a low-cost motor design and have a high level of efficiency. The design of the existing motor cooling system uses a complex design that must use sophisticated machining tools and spend a lot of money in the manufacturing process. The purpose of this paper is to get the geometry of the cooling system on BLDC motor with simple manufacturing process thus saving the cost of production. The expected cooling system design is a simple geometry so that manufacturing can be done using 3-axis CNC machining. Design of cooling system using water-jacket with an additional cover. On this study, Author modeled the motor with Ansys Maxwell to obtain the heat source parameters of the motor geometry. Software Fluent is involved to perform the temperature simulation on the motor using the designed cooling system then validated with an experiment. Thermal analysis of this study compares motor performance with the use of water and oil. The flow rate compared to the radiator power efficiency.
