Re: Variable speed drive said by whizkid3:said by shdesigns:A new VFD and 3P motor will cost you about $300. It could be a good idea, except that not too many people have 3-phase power to their residence. You missed the point, the VFD converts single-phase power to 3-phase. Actually it is a 3-phase PWM signal. Since it is generating the phases, frequency and PWM, it had a lot of control over the motor.
My VFD, has ramp up/down, PWM frequency, current limits, braking and failsafe options.
