Control,osition of the AFPM machine is sensed and fed back to the controller as shown in Fig. 7.1. The controller in its turn controls the supply voltage and frequency of the AFPM machine via the solid-state converter (inverter)..This chapter focuses on all the control aspects of the AFPM machine drive of F

Introduction,sidered. In principle, the electromagnetic design of AFPM machines is similar to its radial flux PM (RFPM) counterparts with cylindrical rotors. However, the mechanical design, thermal analysis and assembly process are more complex.

AFPM Machines Without Stator and Rotor Cores,, P83, 225]. A completely coreless design reduces the mass and increases the efficiency of the machine as compared with a conventional design. Besides this, a coreless AFPM brushless machine does not produce any normal attractive force between the stator and rotor. It also does not produce torque pu

Control, of the AFPM machine. It was also shown that the magnitude of the induced phase voltages is directly related to the frequency and hence the rotor-speed of the AFPM machine. Therefore, for variable speed operation of the AFPM machine both the frequency and magnitude of the supply voltage must be adju
