Abstract
This paper discusses the modeling and analysis of a 120 volt, single-phase AC brushless motor used in an aquarium pump. Single phase motors are used for low volume pumps to simplify the design and to reduce cost The basic operation of the motor is explained. The magnetic flux paths are then described and a circuit model is developed for the two tooth motor. From this model, detent and energized torque are derived using the change in magnetic energy with rotor angle. A mechanical and electrical dynamic simulation is then used to investigate the torque and rotor position during startup and steady-state operation
