A driving method of a high speed rotation stepping motor exhibiting good starting performance, its driving circuit, and a vibration motor and a fan motor employing them. The motor driven electronic apparatus comprises a two pole flat stator, a rotor consisting of a two pole permanent magnet coupling magnetically with the two pole flat stator through a gap, stopping with detent torque and secured to the rotor shaft, and a drive coil. The motor driven electronic apparatus is characterized in that at least any one of the reference voltage of an amplifier constituting a rotor position detector and the reference voltage of a comparator constituting the rotor position detector are used more than one.
