Variable Speed Router
High RPM single phase motor?
I wonder what makes an engine in a turn so fast router. The unit is direct (not directed upwards), monophasic 120 V AC, 60 Hz, with 2 poles. Is it a variable rate? Is there anything else you can do to speed up to 20,000 RPM? phase could be divided, not sure.
It is likely that a universal motor. A universal is essentially a DC motor with a switch and a series connected field winding. It's called "universal" because it can operate with either AC or DC power. Universal motors have been used for many years in power tools, vacuum cleaners and kitchen appliances as mixers and blenders. They can be designed for a wide range of speeds and variable speed provide a good operation. Recently, manufacturers have begun to use DC motors without brushes for some of these application types. PS1 variable frequency drives (VFD) are a bit too large and expensive tool Portable. However, many industrial wood working and metal working tools are equipped with VFD. VFD have been used in commercial heating, ventilation and air conditioning (HVAC) and now are appearing in residential air conditioning systems. The Tesla Roadster has a variable frequency, but not in the wheels and engines In order to minimize UN-sprung weight.
