White Paper Overview
Trapezoidal control is one of the simplest BLDC motor control methods available. By applying square-wave currents to the motor phases that align with the BLDC motor, optimum torque is generated. Benefits of trapezoidal control include over-current protection, over-voltage protection, and over-temperature protection. Combining trapezoidal control with essential protection and design techniques can be one of the most efficient methods of driving an electric motor for power tools and robotics by improving the control and accuracy of the motors.
