My background is mechanical engineering (robotics). I apologize in advance.
I have a sensitive torque ripple (Vibrations) application and would like to use sinusoidal drive to run a 3 phase BLDC motor instead of trapezoidal for low speeds. This is for a speed controller (just inferring torque).
12V motors, 8W peak, estimated 2W Steady state. Unfortunately, I am forced to use the UC1825 pwm controller chip. Can the UC1825 PWM controller output to 6 mosfets (inverter) portion, whereupon it has 3 phase output and 1 for direction?What are comparable sinusoidal drive chips?
Alos, if I could implement this using DSP inside an fpga, would I still need a pwm controller (UC1825) or just an 3-phase inverter ?
