The increasing tendency for cordless implementation is making high energy efficiency a priority in the design of these applications.  

Nowadays, 3-phase Brushless DC motors are becoming more and more popular in low-voltage drives such as power drills, drivers, sanders, grinders and saws. The new control algorithm Field-Oriented Control for BLDC motors has seen a rise in low-voltage drives such as blowers, electric bikes, impact drivers and robotics servo drives.

Let's say you need to implement one of these systems for a new application. Which one do you choose? We will provide you with all information you will need to make the right call.
