Abstract

The utility model relates to a motor for DC and AC dual-purpose electric fan, which is provided with a motor stator and a motor rotor. A motor shaft is arranged in the rotor, and the rotor is provided with wire grooves, and enamelled wires are arranged in the wire grooves; the number of the wire grooves of the motor rotor of the utility model is five, the diameter of the enamelled wires arranged in the wire grooves is 0.23 mm to 0.31 mm, and the number of turns is 80 to 100. Because the electric fan driven by the motor is DC and AC dual-purpose electric fan mainly used in areas with lack of alternating current power sources, particularly in the case of power failure, definited requirements of the number of the grooves, the diameter of the wires, the number of turns, etc. of the motor are put forward. If the structure of a shaft head of the motor is more reasonably matched with leaves of the electric fan, the shaft head can be provided with a clamping sping groove, etc.

Description

The AC/DC fan motor

Technical field

The utility model relates to motor, particularly relates to the AC/DC fan motor.

Background technology

Electric fan is a class household electrical appliance commonly used, and use amount is very big, and is of a great variety.What existing electric fan adopted is the 220V AC power, and equipped is alternating current machine, therefore, runs into power failure in electricity consumption area in short supply or does not have the place of AC power just can't use.So need exploitation AC/DC electric fan, thereby corresponding motor that requires design AC/DC electric fan.When the AC/DC electric fan used, when alternating current supply, alternating current converted direct current supply motor to through transformation, rectification, and when not having AC power, and by storage battery power supply, what this shows that the AC/DC electric fan uses is direct current machine.And the direct current machine and the AC/DC electric fan that still lack this kind at present are supporting.The spindle nose of existing in addition motor shaft is installed the fan leaf and is adopted nut etc. fixing, and trouble is installed.

Summary of the invention

The purpose of this utility model provides a kind of supporting with the AC/DC electric fan, and laborsaving, the firm AC/DC fan motor of fan leaf is installed on the spindle nose of motor shaft.

The technical scheme of the utility model AC/DC fan motor is: motor stator and rotor are arranged, motor shaft is installed in the rotor, rotor is shaped on wire casing, enamelled wire is installed in the wire casing, the groove number that it is characterized in that the rotor wire casing is 5 grooves, the enamelled wire line of installing in the wire casing directly is the 0.23-0.31 millimeter, and the number of turn is 80 circles-100 circles.The length of its motor shaft is the 80-90 millimeter, is shaped on jump ring groove or pinhole on the spindle nose of motor shaft, perhaps is shaped on one-sided plane on the spindle nose of motor shaft.Because the electric fan of this driven by motor mainly is in AC-powered area in short supply, particularly under power-off condition, use, consider that parameters is that the voltage of motor is that 12V is good, load current≤1.6A, input power≤19W, power output 〉=6W is so propose to limit requirement to groove number, line footpath and the number of turn etc. of rotor; Again because consider that motor shaft head and fan leaf are easy for installation, firm, so on the spindle nose match with the leaf keyway in fabrication spring groove or pinhole or one-sided plane.

Embodiment

The utility model discloses the supporting motor 1 of a kind of AC/DC electric fan, motor stator and rotor are arranged, motor shaft 2 is installed in the rotor, rotor is shaped on wire casing, enamelled wire is installed in the wire casing, the groove number that is primarily characterized in that the rotor wire casing is 5 grooves, and the enamelled wire line of installing in the wire casing directly is the 0.23-0.31 millimeter, and the number of turn is 80 circles-100 circles.The line that a special case is arranged is enamelled wire directly is 0.25 millimeter, and the number of turn is 94 circles.Its motor shaft 2 length are 80-90 millimeters, and the best is the 80-85 millimeter.Be shaped on jump ring groove pinhole 3 or pinhole on the spindle nose of motor shaft 2, install and to fix by jump ring behind the fan leaf or pin is fixed, convenient firm.Perhaps on the spindle nose of motor shaft 2, be shaped on one-sided plane 4, cooperate, rotate non-slip with the strong groove of fan leaf.This empty load of motor electric current≤0.2A, voltage 12V, no-load speed 3000-3600 rev/min, load current≤1.6A, moment of torsion 〉=0.04NM, load speed 1200-1800 rev/min, power output 〉=6W, efficient 〉=33%, input power≤19W.
