The master’s thesis focuses on the development of a battery-powered brushless
direct current motor controller, with an emphasis on temperature optimization.
The operation of the control circuit board is based on an existing software code,
but it differs from previously developed control circuit boards by being integrated
directly onto the motor contacts.
The master’s thesis begins with the basics of BLDC motors and their control,
followed by a detailed description of the control circuit board. Next, the theory
of MOSFET transistor losses and the theory of heat dissipation mechanisms are
presented; the latter is finally verified by temperature measurements.
