Optimizing development of a bipolar stepping motor with electronic circuit for quartz analogue clocks
Abstract
Alternatives concerning stator assembly, stator material and rotor material in conjunction with drive are shown in accordance with the objective. The specifications for an integrated circuit are defined with regard to motor drive, also buzzer systems including drive were investigated for the optimum cost-performance ratio. Possibilities for a larger integration depth (hybrid assembly system) of IC and quartz crystal are discussed in view of automatic oscillator frequency alignment.
