Determination of Stray Losses Using myDAQ

Authors : A. Sathishkumar, P. Sridhar and S. Swathi

Abstract: DC machine is a versatile electrical machine. Its particular test is used for DC shunt motors and generators. It is arrived at the stray losses from measured values of armature losses and copper losses for given load current. Efficiency can be measured from these values. The machine is run up slightly beyond its normal speed and then supply is cut off from the armature while keeping the field excited. The armature slows down and its stored energy is used to meet therotational losses, i.e., friction. The required data of a machine are sensed by myDAQ and hence, the losses are determined. After determination of the losses, DC machine efficiency is determined while it is acting as motor. This study introduces automation of the machine to calculate the losses in a machine.
