The basic work of an inverter within a VSD is simple. A microcontroller integrated with the inverter manages the speed of a motor according to demands. For example, in a refrigerator data such as temperature, humidity and motor speed are gathered through sensors to keep the motor running efficiently.
155:
A fixed speed drive can run in two states: on or off. The energy consumption of such a system is higher because it runs at full power even when that is not needed. Fixed speed drives are designed to manage starting at full speed, which does not maximize efficiency. An

Inverterization has multiple applications in home appliances and industrial drives. Most major home appliances, including refrigerators, washing machines, fans, vacuum cleaners and pumps, are inverterized.

Reducing motor speed saves energy. For example, slowing down a fan motor from 100% to 80% when less airflow is needed can save as much as 50% ofn energy use.
189:
Higher durability through smoothly starting engines improves efficiency through an increase in power factor, and improves process control.

Based on such data, a microcontroller optimizes performance. Motor speed is optimized and keeps the refrigerator’s temperature constant.
