Automotive 12V Three Phase Motor Drive

Automotive 12V 3-Phase Motor Drive

3-phase motors are becoming more popular in automotive applications when power levels exceed 100W. They are cost-effective and improve reliability when compared to brushed motors by eliminating the brushes and associated concerns.
