Abstract
The loss minimization in surface permanent-magnet synchronous
motor drives is investigated. Based on theoretical analysis, a loss
model controller is introduced to specify the optimal air-gap flux that
minimizes losses. Theoretical results are verified experimentally. The
proposed loss model controller is simple and does not adversely affect
the cost and complexity of the drive. Implementation of the loss model
controller does not require knowledge of the loss model. The suggested
loss minimization method can be applied both in V/f- or
current-controlled schemes
