Sensorless Speed Control of Brushed DC Motor Based at New Current Ripple Component Signal Processing

Sensorless Speed Control of Brushed DC Motor Based at New Current Ripple Component Signal Processing

Signal processing of the brushed DC motor current was developed in this paper to obtain information about a rotor speed from a measured motor current. The brushed DC motor current contains a signal with a frequency proportional to the rotor speed. This signal is the outcome of a commutation process...
