Description

Technical Field

[0001] The utility model relates to the technical field of driving equipment, in particular to a high-efficiency energy-saving motor for a pump. Background Art

[0002] Electric motors, commonly known as motors, refer to electromagnetic devices that convert or transmit electrical energy based on the law of electromagnetic induction. Electric motors usually include a stator and a rotor. The stator includes a stator core and a coil winding wound on the stator core. The rotor includes a rotating shaft and a rotor core sleeved on the rotating shaft. A permanent magnet is provided on the outer edge of the rotor core. Electric motors are generally divided into DC motors and AC motors. At present, energy-saving motors are needed when pumps are driven.

[0003] The utility model with the prior art publication number CN214256040U relates to a high-efficiency energy-saving motor, including a machine base, a motor body is installed on the top of the machine base, a front end cover is fixed on the periphery of one end of the motor body, an output shaft is horizontally penetrated in the middle of the front end cover, a rear end cover is fixed on the periphery of the other end of the motor body, a heat dissipation impeller is installed in the middle of the rear end cover, and a dust-proof vent connected to the inner cavity of the rear end cover is opened in the middle of the other end of the motor body. The high-efficiency energy-saving motor drives the heat dissipation impeller to rotate when the output shaft is working, thereby cooling the heat diffused to the rear end cover, and a cylindrical cooling water tank is arranged on the periphery of the motor, and the heat generated by the motor is transferred to the cooling water in the cylindrical cooling water tank, wherein a part of the increased water temperature is dissipated through the heat dissipation fins, and the other part is dissipated by the heat dissipation fan in the heat dissipation frame, thereby ensuring high-efficiency heat dissipation, reducing the working energy consumption of the motor, and improving the working efficiency of the motor.

[0004] However, the above device still has the following problems when in use: when the existing high-efficiency energy-saving motor for pumps is used, it often requires the pump machinery to drive for a long time at a high load. After the motor body works for a long time, it is very easy to accumulate heat, resulting in increased energy consumption. However, the air-guiding and heat-dissipating efficiency of the existing impeller mechanism is limited. In addition, when the existing high-efficiency energy-saving motor for pumps is combined and fixed, its matching installation structure is single, and often only a single installation work can be performed, and its matching installation flexibility is poor.
