Abstract
A motor assembly in which magnetic attraction between the magnets and the base of the motor is reduced by providing increased magnetic reluctance. This is achieved without the need to increase the overall height of the motor assembly, thus making the motor assembly particularly suitable for use in applications with tight space constraints and power consumption limitations.
