In some applications, it is interesting to know the position of a BLDC Motor at standstill. This paper propose one solution using the saturation property of the motor. Principle, simulation and measures are presented. The results of industrial applications ...
This paper describes a low cost sensorless position detection scheme for a brushless DC motor. This method is based on interruption of the 3 phase-currents and reading the back-EMF. The hardware for measuring the back-EMF is very simple. The method is poss ...
Today, the use of brushless DC motors (BDCM) in robotic applications is only at its beginning in spite of their remarkable features. This is due to the increased complexity of the control with respect to the conventional DC motors, but also to the parasiti ...
A multispeed testing method for obtaining tool-life parameters using radioactive tools has been developed. By suitable interpolation of the instantaneous rates of absolute wear measured for a number of discrete cutting speeds, the corresponding tool-life v ...
