Physical changes occur when objects or substances undergo a change that does not change their chemical composition. This contrasts with the concept of chemical change in which the composition of a substance changes or one or more substances combine or break up to form new substances. In general a physical change is reversible using physical means.
12-17 can be reversed by changing the polarity of the armature winding. If the motor has interpoles, the polarity of the interpole must be changed when the armature's polarity is changed. Since the interpole is connected in series with the armature, it should be reversed when the armature is reversed.his type of motor is called a differential compound because the polarities of the shunt field and the armature are opposite. The cumulative compound motor is one of the most common DC motors because it provides high starting torque and good speed regulation at high speeds.
