The utility model belongs to the technical field of water pumps, and discloses a novel water pump based on a brushless motor, which comprises a bottom plate and a
plunger pump assembled above the bottom plate, an
assembly plate is assembled outside the
plunger pump, the output end of the
plunger pump is fixedly connected with an output shaft, and the output shaft is fixedly connected with the brushless motor. A transmission structure used for being connected with a brushless motor is assembled at one end of the output shaft, the
plunger pump is matched with the transmission structure, the transmission structure is connected with an external brushless single
machine, after
electrification, current is transmitted to a
stator coil to generate an induction
electromagnetic field to drive an outer rotor to rotate, and a
motor shaft is directly connected with a water pump main shaft to drive the
plunger pump to operate.
Power transmission is direct and efficient,
energy loss is reduced, a brushless motor is adopted, stepless pressure regulation is achieved in cooperation with PWM speed regulation, different working condition requirements can be accurately met, and compared with a water pump with the same pressure and flow in the market, the water pump is smaller in size, lighter in weight, convenient and fast to install and transport, large in flow and
water pressure and excellent in conveying performance.
