Comparison of square wave and sine wave drives for brushless DC motors

Compared with the sine wave drive, the brushless DC motor square wave drive has the advantages of simplicity, low cost, and high material utilization, but it has the disadvantages of large torque ripple. However, with good design and control, square wave drives can reach the level of brushed DC servo motors and are suitable for systems with average performance.
