NettetThe compound wound DC motor utilizes the features of both series wound & shunt wound DC motor. it combines both the parallel combination as well as the series combination of the field & armature windings. Due to the combination of the series & parallel windings, the compound wound motors can be classified into the following two … NettetCompound Wound DC Motor; Series DC Motor. The series DC motor is the one in which the field winding is connected in series with the armature winding as shown in the figure. From the above circuit, it is clear that the series field winding of the motor carries the entire armature current, therefore, it is designed to have low resistance. sac zim bog to two harborsNettetOperating Characteristics. Wound rotor motors are usually started with maximum resistance in the rotor. This provides maximum starting torque in the range of 225% of the full-load torque. This is in the range of the breakdown torque of the motor. At the same time, the resistance limits the starting current to about 150% of the full-load current. sac à dos eastpak out of office cloud navy
