Low cost sinusoidal control of BLDC motors with Hall sensors using ST7FMC
ثبت نشده
چکیده
BLDC motors are the workhorses in most light industrial applications. In some cases, Halleffect position sensors are used to simplify control logics for controlling these motors. BLDC motors, by the nature of currents through them, are somewhat noisy and a little less efficient. These disadvantages plus the cost of sensors are an integral part of these drive systems. However, if the motor can be driven with sinusoidal currents, preferably with only one Hall-effect sensor, these drawbacks can be greatly reduced.
