Hi guys,
An ordinary DC motor can be converted into a servo motor using an encoder connected to it's shaft.A driver/controller takes the signals from the encoder and acts accordingly to control the speed of the motor(using PWM or something like that).The question is that when the motor is stopped at a certain angle how can it maintain it's stalling torque(like a stepper motor does) or how does the driver keep the motor at that certain angular position without applying any power to the motor(An ordinary motor can be stopped by cutting the power) and also not letting the load to move it's shaft.
Thank You, prizark.
