This method is compared to the well-known direct field-oriented control (FOC) and stator flux vector control (SFVC) methods.

Earlier we talked about how accessors are slower than direct field accesses, so this is an example of a certain language idiom resulting in an "invisible" performance hit.

Field access may be marginally faster, but rarely. Sometimes, getter access may provide a slightly different value from direct field access, especially when subclasses are in play.
