Title: Brushless motor drive system
Inventor: NANAE YUUICHI
IPC: H02P6/28
Filed: 1990-01-26
Abstract: PURPOSE:To reduce the number of magnet position detecting element required for polyphase driving by producing a polyphase position signal having no phase error from position detection signals provided from three magnet position detecting elements and then producing a conduction signal to be employed for polyphase driving from thus produced polyphase position signal. CONSTITUTION:Three magnet position detecting elements H1-H3 are arranged with electrical angles of 120 deg. and position detection signals from the magnet position detecting elements H1-H3 are subjected to subtraction thus producing three sinusoidal position signals where tertiary higher harmonic components are cancelled. These three position signals are then weighed and added to produce a polyphase position signal and a conduction signal required for polyphase driving is produced from thus produced polyphase position signal. Consequently the number of magnet position detecting element required for polyphase driving can be reduced to three without sacrifice of motor performance such as fluctuation or lowering of torque.
