Patent number: 11362605Abstract: A method of driving a three-phase motor includes, while a first phase is energized, driving a second phase using a first drive function which is sinusoidal. The first phase is switched to a non-energized state and a back electromotive force (BEMF) voltage of the first phase is detected. For at least a portion of a time when the first phase is non-energized the driving of the second phase depends on the output of a second drive function different from the first drive function. The second drive function may be non-sinusoidal and may be a cosine function. The second drive function may drive the second phase when the output of the second drive function is a modulation ratio less than 1. When the output of the second drive function is a modulation ratio greater than or equal to 1 the second phase may be driven to a modulation ratio of 1.Type: GrantFiled: January 29, 2020Date of Patent: June 14, 2022Assignee: SEMICONDUCTOR COMPONENTS INDUSTRIES, LLCInventors: Kazumasa Takai, Fumio Kumazawa, Masaki Yamashita

Patent number: 9099944Abstract: To provide a disk drive capable of inhibiting the occurrence of acoustic noise caused by a voltage pulse when the head is retracted using a speed control method using voltage obtained by rectifying a back electromotive force after the power source has been cut off from the rotation of a spindle motor. Retraction control circuit is used to control the on and off modes of transistors in accordance with the speed of VCM. The voltage across VCM becomes a voltage that can be regulated with VCM voltage control circuit. At this time, voltage is supplied to the terminals based on the voltage of ISO5V that is the rectified voltage of the back electromotive force of the spindle motor and the pulsating voltage is synchronized and produced at both terminals. As a result, the potential difference across VCM is such that the pulsating voltage is negated and acoustic noise is inhibited.Type: GrantFiled: March 26, 2014Date of Patent: August 4, 2015Assignee: TEXAS INSTRUMENTS INCORPORATEDInventors: Masaki Yamashita, Chisako Asaoka, Nobuhiko Wasa
