There are strict requirements regarding in-vehicle products, and this additionally applies to those mounted within motors themselves. Increases in motor efficiency are in a direct relationship with being able to reduce physical sizes, which allow for such improvements. Motor control is one method of increasing motor efficiency. Our company worked in analyses with the objective of increasing efficiency with timing optimization using JMAG, focusing on FET switch timing in motors using our PAM inverter circuit.
