Re: [CAD_CAM_EDM_DRO] Re: why not just change the motor? VFD Question ??

Here you go.
Question what is sensorless vector?
Sensorless vector control is a technique used in variable frequency drives
to rotate the force vector in the motor without the use of a shaft position
sensor. The goal of ac sensorless vector technology is to give the user "dc"
like control while making traditional speed or shaft position feedback from
the motor unnecessary. The SV control removes a major source of complexity
and potential for failure (the tach. feedback), while simplifying many ac
drive installations

Any further questions about drives? Got to website listed bellow......
