Unbelievable Dc Series Motor Circuit Diagram

E b back emf.

Dc series motor circuit diagram. The self excited motors are further classified as shunt wound or shunt motor series wound or series motor and compound wound or compound motor. Armature circuit connections some motors are furnished with a stabilizing series field s1 s2. I l line current.

When voltage is applied current flows from power supply terminals through the series winding and armature winding. The circuit diagram of the proposed dc motor speed controller can be seen below. The construction of the dc motor and generator are the same.

The working principle of the dc motor. On the other hand when the wiper arm of vr1 is at the bottom position c1 charges through r1 r2 and vr1 and discharges via r2. Therefore the motor speed is slow.

The circuit diagram corresponding to the dc series motor the field and armature winding are connected in series is depicted. A series wound dc motor like in the case of shunt wound dc motor or compound wound dc motor falls under the category of self excited dc motors and it gets its name from the fact that the field winding in this case is connected internally in series to the armature winding thus the field winding are exposed to the entire armature current unlike in the case of a shunt motor. In a series motor electric power is supplied between one end of the series field windings and one end of the armature.

But the dc motor has a wide range of speed and good speed regulation in electric traction. Where v t input voltage. Figure 4 shows the automatic dc starter circuit diagram.

The equivalent circuit corresponding to this motor is shown in the figure. When the wiper arm of potmeter vr1 is in top position capacitor c1 charges through r1 r2 and d1 and produces a pulse train at the output of ic1 with long negative and short positive pulse widths. R f field winding resistance.
