Title:
MOTOR DRIVING CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2019/080793
Kind Code:
A1
Abstract:
A motor driving circuit. The motor driving circuit comprises a first switch (K1), a second switch (K2 and 30), a third switch (K3 and 40), and a first transistor (Q1), where: one end of the first switch (K1) is connected to a power supply (VCC), the other end is connected to the second switch (K2 and 30) and the third switch (K3 and 40); both the second switch (K2 and 30) and the third switch (K3 and 40) comprise a first interface, a second interface, and a third interface, the first interface is electrically connected to the second interface or to the third interface, the first interface of the second switch (K2 and 30) and that of the third switch (K3 and 40) are connected to a motor (10), the second interface of the second switch (K2 and 30) and that of the third switch (K3 and 40) are grounded, the first interface of the second switch (K2 and 30) and that of the third switch (K3 and 40) are connected to the first switch (K1); and the first transistor (Q1) is connected between the second interfaces of the second switch (K2 and 30) and of the third switch (K3 and 40) and the ground. The described solution solves the problem that an existing motor driving circuit is incapable of adjusting load capacity.
