I would suggest browsing the Microchip application notes on motors. They ha= ve quite a lot of information on BLDC motors in them. -----Original Message----- From: piclist-bounces@mit.edu On Behalf Of Jason = White Sent: 05 August 2018 17:18 To: Microcontroller discussion list - Public. Subject: [EE] can a 160V 3-phase brushless motor be used with AC VFD? Hello, I am working on rewiring a small CNC mill. For the spindle the existing uni= t has the following brushless DC motor with hall effect sensors (see attach= ed drawing). It is rated at 160V, 7A. Could this motor be driven by a VFD intended for conventional 3-phase AC in= duction motors? As I understand it most 3-phase AC motors are 220Vac which = would suggest that the answer is no. For this application I do no care about slippage or precise speed.
