Model No. 169: The aim of the project is to design a contactless speed sensing device (techometer) for a Brushless DC (BLDC) motor. Traditional tachometers require a physical contact to the shaft of the motor to measure the speed. In certain applications, where it is not feasible to measure the speed for safety and technical reasons, it is possible for a contactless techometer to take the readings from a certain distance.
