Myson Motor Controller IC Solutions CS6257 FOC/VC Benefits:

FOC/VC overcomes the low-speed imprecision of trapezoidal motor control, as well as the high-speed inefficiency experienced with conventional sinusoidal control.

In addition to reducing energy consumption, FOC delivers advantages such as lower audible noise, reduced wear, constant torque over the complete speed range including zero-speed operation, and good velocity control under varying load conditions.

Essential hardware-based execution of the computationally intensive FOC calculations, as well as built-in analogue IP optimized for motor control, avoids the complications and performance limitations experienced when implementing FOC in pure software.
