The Losses in DC Machines The losses that occur in DC machines can be divided into four basic categories: 1. Electrical or copper losses 2. Core losses 3. Mechanical losses 4. Stray load losses ELECTRICALOR COPPER LOSSES. Copper losses are the losses that occur in the armature and field windings of the machine.
1. This magnetizing current lags behind the supply voltage, V 1 by 90° and produces the flux ϕ, which induces the primary and secondary emfs. These emfs lag behind the flux, ϕ by 90°. The magnitude of primary induced emf E 1 and supply voltage V 1 is the same, but are 180° out of phase.
