A lot of good information be shared here by all. I can sometimes be vague or use wrong terminology, for which I apolgize. When posting about the Rotary Phase Converter, the term Pony motor was used in place of what the video calls the idler. This ”idler” must Be in operation continously. And due to losses , needs to be bigger than the motor your trying to drive.
The windings within the idler motor interact with the driven motor to produce the end current phases.
My Capacitor Phase Converter post . Correct Terminology : Static Converter, Uses 3 large capacitors and a small relay board.It is called an AutoGen, model CD14, made by Smith Electric Motorworks GWM, Marceleine , Mo. For “moderately. Loaded 3-7hp 3ph motors. These work great. For small lathes. Physical size: 7”x 4 1/2” x 9 1/2”. No “idler required”
Smith Electric Motorworks’web site has nice training and application link, describing their diffent type converters.
When I posted about using a several 100Hp motor to start a gas turbine; that starting motor is called a pony motor. (pony motor: a small auxiliary motor used to get a prime mover , moving.) in the case of your automobile: the electric starter is a pony motor.
The VFD basic function is to control speed and torque. Speed determined by the frequency of applied current (and physical number of poles.) Other parameters are in the process, thus the wave shape changes.
PWM can part of the scheme. I think PWM control applies more to. DC motor control.
