More Information
Summary:A brushless motor device including: a rotor; a stator including a first coil, a second coil and a third coil, first ends of which are Y-connected to each other; a motor driver including an inverter circuit including switching elements and configured to: switch ON and OFF states of each switching element of the inverter circuit, wherein by switching the ON and OFF states of each switching element of the inverter circuit, the motor driver is configured to switch an energization time period from a first time period in which current is caused to flow from the first coil to the third coil to a second time period in which current is caused to flow from the second coil to the third coil and set both voltages of second ends of the second coil and the third coil to a power supply voltage during the second time period.
