1 Introduction

Although most small drives cover the power range between 40 W and 2.2 kW, their configuration is
quite different depending on the application. The compressor of an air conditioner, the drum drive of a
washing machine and the spindle drive of a numeric controlled lathe may all have the same power
ratings of about 750 W. But they strongly differ in their control algorithms and inverter set-ups assuming
the same electrical motor, either and induction machine or a brushless DC type. While the operation of
a fan or a compressor might be already sufficient with an open loop voltage-frequency control, the
washing machi……
