the hysteresis loss in a DC Machine varies with the frequency of the magnetic reversal is directly proportional to the weight of the iron present.
Explanation:
- hysteresis is a special type of loss of energy which takes place in a DC motor. A DC motor works on the principle of the the force which takes place in the arms of the motor when it is placed in a variable magnetic field.
- as a result of this when there is change in the polarity of the magnet there is some amount of energy that is lost. The hysteresis loss increases with increase in the mass of the iron and increase in the density.
