Commonly seen in various types of motor, the interior is the core and winding coil. Windings have resistors, electricity will produce loss, the loss of the size and resistance and current square in direct proportion, this is what we often say copper loss, if the current is not a standard DC or sine wave, but also generate harmonic losses; The core has hysteresis vortex effect, in the alternating magnetic field will also produce loss, its size and material, current, frequency, voltage, It's called iron loss. Copper loss and iron loss will be expressed in the form of heat, thus affecting the efficiency of the motor.
