Variable frequency drives convert ac power to dc and then reshape that current to control ac motors. All types control speed by varying current frequency, but one subtype — flux vector drives — uses ...

High-performance motors need a control mechanism that ensures enhanced smoothness, reliability, and efficiency. One of the most apt examples of such an application is the motor used in ...

{Editor's note: This article originally appeared as a series of blogs in EE Times. It is replicated here in its entirety for the convenience of the EDN community.} Motors are all around us, and an ...

OEMs and hobbyists benefit from technology’s trickle-down effect. Figure 1. Many industrial applications and small machines with a motor and limited I/O requirements can benefit from using AC VFDs with ...

The past few decades have seen a rise in the use of field-oriented control in induction motor applications. One advantage of field-oriented control - or as some call it, vector control - is that it ...

BorgWarner. has been granted a patent for a method of motor control using a complex vector flux regulator (CV?R). The method involves receiving a modulation index ...
