Measurement of addi t ional harmon ic losses of mo tors fed by con verters

•

define test methods for determining the additional harmonic motor losses of converter-fedinduction motors

• the motor is part of a Power Drives System (PDS), see EN 50598-2

• Aim: to create a comparability between motors regarding their additional harmonic losses

• Measurements are performed under standardized conditions with the motor supplied by a

reference converter (uncontrolled 2 / 4 kHz PWM converter without over-modulation)

• The measured losses are for reference only and do not represent the actual losses in any

given application
