Field Control Resistance at Clarence Ellsworth blog

Field Control Resistance. When the resistance added to the field is zero then the current. It's most common to lower speed under light loads. Conversely, we may increase a dc motor’s speed (and reduce its torque output) by increasing the field control resistor’s resistance, weakening the stationary magnetic field through which. Armature resistance control method for dc series motor. Where, v a is the voltage applied across. This approach requires controlling the resistance in connection to the supply. Tm = (k1 kf ia)if. Also, tm ∝ kf if ia. Speed control of dc motor by field resistance control. We know that the speed of shunt motor is given by: In field control method, a varying external resistance is connected in the field circuit. The torque tm developed by the motor is proportional to the armature current i.e. Speed control of dc series motor is done by the armature control and field control methods. This method controls speed by inserting a variable resistance in series with the shunt field, which decreases the field current and flux but.
