| Abstract |
Sensorless operation of conventional eld oriented asynchronous drives around
the zero stator frequency region is problematic due to lack of information for the flux
observer. A novel modular vector drive circumvents this problem by ensuring that
operation of individual modules is outside said region. This paper examines from a
magnetic perspective how the motor is a ected by this type of operation. An analytical
and nite element based approach is presented which determines the flux density
distribution in the modularised motor. Results from these studies concludes that its
magnetic behavior is signi cantly changed when operation takes place in the zero
frequency region. This implies that the motor design must be adapted to allow this type
of modular drive control. |
