Electric motors should make torque, not noise!

Most COTS motor controllers use simple 6-step trapezoidal commutation. Just like footsteps, these 6-steps create impact points in the rotation in the form of  torque ripple and electrical harmonics in the motors.  This results in reduced efficiency, and yes even sound!  Our Taurus motor controllers implement Field Oriented Control (FOC) and Space Vector Pulse Width Modulation (SVPWM) resulting in much more continuous torque delivery, increases in efficiency, and reduction in unwanted heat generation and noise. Our technology is fundamental to quiet, efficient vehicle operations for electric and hybrid-electric systems.
