Abstract:

The single-phase DC motor has the low-cost advantage over 3-phase DC motor owing to its easy-assembling and high yield-rate, however, it has larger torque ripple and clogging torque. Single-phase DC motor is currently applied to low profit margin products such as cooling fan. In order to utilize single-phase DC motor to high precision system, for instance, DVD Digital Versatile Disk, the vibration caused by torque ripple and cogging torque needs to be solved. In this paper, focusing error, tracking error, seeking ability and some velocity control performances are studied when single-phase DC motor is used in DVD related products.
