Aerospace electric machine manufacturers are often limited with respect to the implemented cooling mechanisms. That is, natural convection systems are the norm, as fan cooled and fluid cooled machines may suffer from reliability issues.The original contribution of this work, is the design, testing, and implementation of an alternative forced cooling convective system (FCCS) based on piezoelectric fans.This thesis commences by an investigation of the capabilities of MotorCAD (a sophisticated analytical lumped thermal package) and how it can be utilised in a fully integrated way to optimise (for a maximum power density and an overall minimum motor mass) both the electromagnetic and thermal aspects of a typical traditional horizontally mounted permanent magnet synchronous machine (PMSM) operating at flight level. The resultant analytical temperature values were then compared to actual experimental temperature data.Piezoelectric fans are then investigated as a potential, fault tolerant FCCS that may enhance the overall cooling of a motor.

Democrats in the New York State Assembly will weigh rescinding Governor Cuomo’s emergency powers as one of his top aides attempts to walk back her stunning admission that the administration covered up the true number of COVID nursing home deaths in order to avoid being attacked by the Trump administration. The Democratic lawmakers plan to hold a conference Friday morning to discuss stripping the governor of the emergency powers granted to him last year when the pandemic began, local news outlet NY1 reported. She apologized to state Democratic lawmakers during a recent video conference call, saying “we froze” out of fear that the true death toll would “be used against us” by federal prosecutors.
