BRUSHLESS MOTOR
Document Type and Number:
WIPO Patent Application WO/2018/147054
Kind Code:
A1
Abstract:
This motor (1) is provided with switching units (E1, E2, F1, F2, G1, G2) that switch a connection of a first stator coil (U1) and a second stator coil (U2) between a serial connection and a parallel connection on the basis of operation information. One end (U1a) of the first stator coil (U1) is electrically connected to one end (U2a) of the second stator coil (U2) through the switching units (E1, F1). Also, the other end (U1b) of the first stator coil (U1) is electrically connected to the other end (U2b) of the second stator coil (U2) through the switching units (E2, F2). The switching unit (F1) is electrically connected to the switching unit (E2) through the switching units (G1, G2). Switching between the serial connection and the parallel connection is performed by appropriately switching the switching units (E1, E2, F1, F2, G1, G2).
