To get the optimum performance from the motor, the drive current should match the back Electro Motive Force waveform. As back EMF of BLDC motor is in trapezoidal shape it should be driven with trapezoidal current to get best performance. Trapezoidal commutation is also known as \u201cSix Step Commutation\u201d because there are total six steps of drive current used to complete one revolution of rotor. In trapezoidal control at a time only two phase are active. This method has simple control algorithm but the torque ripple exist in the motor at every commutation(60 Degree).<\/p>\n<p><img decoding=\"async\" loading=\"lazy\" src=\"https:\/\/bacancysystems.com\/blog\/wp-content\/uploads\/2021\/08\/BLDC-motor-min.jpg\" alt=\"BLDC motor\" width=\"1100\" height=\"637\" class=\"aligncenter size-full wp-image-19724\" srcset=\"https:\/\/bacancysystems.com\/blog\/wp-content\/uploads\/2021\/08\/BLDC-motor-min.jpg 1100w, https:\/\/bacancysystems.com\/blog\/wp-content\/uploads\/2021\/08\/BLDC-motor-min-300x174.jpg 300w, https:\/\/bacancysystems.com\/blog\/wp-content\/uploads\/2021\/08\/BLDC-motor-min-1024x593.jpg 1024w, https:\/\/bacancysystems.com\/blog\/wp-content\/uploads\/2021\/08\/BLDC-motor-min-768x445.jpg 768w\" sizes=\"(max-width: 1100px) 100vw, 1100px\" \/><\/p>\n<h3>Advantages<\/h3>\n<ul class=\"bullets text-left\">\n<li>Control Algorithm is simple<\/li>\n<li>Only two phase is needed to active at time<\/li>\n<li>Less switching losses<\/li>\n<\/ul>\n<h3>Disadvantages<\/h3>\n<ul class=\"bullets text-left\">\n<li>Torque ripple at every commutation<\/li>\n<li>Torque produced is less<\/li>\n<li>Acoustic and electric noise<\/li>\n<\/ul>\n<h2>Sinusoidal Control<\/h2>\n<p>The Sinusoidal commutation is used in Permanent Magnet Synchronous Motors because the PMSM motor has the sinusoidal back EMF. Although theoretically, the back Electro Magnetic Force waveform of a BLDC motor is trapezoidal, but the inductance in the motor smoothens it into a sinusoidal shape. This is why BLDC motor can use either of the two- trapezoidal or sinusoidal commutation methods.<\/p>\n<p>As its name suggests the shape of the back EMF and drive current is sinusoidal in this method. Sinusoidal control eliminates the torque ripple and give smooth motion. The basic principle of sinusoidal commutation is to provide sinusoidal current which vary according to rotor position. The current are phase shifted by 120 Degrees. Sinusoidal control is achieved by using Field Oriented Control Algorithm. The basic principle of this algorithm is that the maximum torque is produced when rotor and stator magnetic field are orthogonal to each other. So sinusoidal current varies according to rotor position to get maximum torque and smooth motion.<\/p>\n<p><img decoding=\"async\" loading=\"lazy\" src=\"https:\/\/bacancysystems.com\/blog\/wp-content\/uploads\/2021\/08\/BLDC-motor-min-1.jpg\" alt=\"BLDC motor\" width=\"1100\" height=\"609\" class=\"aligncenter size-full wp-image-19725\" srcset=\"https:\/\/bacancysystems.com\/blog\/wp-content\/uploads\/2021\/08\/BLDC-motor-min-1.jpg 1100w, https:\/\/bacancysystems.com\/blog\/wp-content\/uploads\/2021\/08\/BLDC-motor-min-1-300x166.jpg 300w, https:\/\/bacancysystems.com\/blog\/wp-content\/uploads\/2021\/08\/BLDC-motor-min-1-1024x567.jpg 1024w, https:\/\/bacancysystems.com\/blog\/wp-content\/uploads\/2021\/08\/BLDC-motor-min-1-768x425.jpg 768w\" sizes=\"(max-width: 1100px) 100vw, 1100px\" \/><\/p>\n<h3>Advantages<\/h3>\n<ul class=\"bullets text-left\">\n<li>No torque ripple in commutation<\/li>\n<li>Smooth motion<\/li>\n<li>Maximum Torque is produced<\/li>\n<\/ul>\n<h3>Disadvantages<\/h3>\n<ul class=\"bullets text-left\">\n<li>Possible to have three phase on same time<\/li>\n<li>Higher Switching losses<\/li>\n<li>Control Algorithms are complex and mathematically intensive<\/li>\n<\/ul>\n<p>Practically BLDC and PMSM motor can run from any two methods because as said earlier we are not getting exactly trapezoidal back EMF but it somewhat looks like sinusoidal.<\/p>\n<p>Although sinusoidal control algorithms are complex to implement,to get maximum torque and smooth motion in applications sinusoidal control should be used.In applications where less torque is not an issue,driving the motor with simple control algorithm with trapezoidal control is a better idea.<\/p>\n<h2>Conclusion<\/h2>\n<p>WIth this we conclude the blog discussion.
