How an Inverter Can Reduce Electricity Costs

Article details

1. How an inverter works

An inverter changes frequency (Hz), allowing motor speed to follow the actual load instead of running at full speed continuously.

2. Energy saving

The source states that a small reduction in speed may result in a much larger reduction in electricity use, with typical savings of 20–50% depending on the machine and application.

3. Soft start and stop

Soft start and stop reduce starting-current surges, motor-winding heat and mechanical shock to belts and gear systems.
