Abstract
The utility model discloses an energy-saving direct-current motor. The motor comprises a motor base, and a stator and a rotor mounted in the motor base. Enamelled wires winded on the stator and the rotor are formed in a manner that a layer of silver is additionally arranged between a copper wire and insulating varnish, and the thickness of the silver is 1/4 to 1/10 of that of the copper wire; and a coil of the stator and an armature winding of the rotor are formed by 3-5 silvering insulated enamelled wires stranded together. An external end of a commutator bar of a commutator of the rotor is provided with a groove. As the coils in the motor are formed by the silvering enamelled wires, the resistance of the coil is reduced, the inductance factor of the motor is increased, the power consumption is reduced, and the energy is saved. Besides, the commutator bar of the commutator has a groove, so that a protective film can be built while a brush contacting with the commutator, thereby reducing the temperature rise of the motor, and preventing sparks generated between the commutator and the brush.
Description
Technical field
The utility model relates to a kind of motor, particularly relates to a kind of energy saving dc motor.
Background technology
At present, existing DC motor ubiquity power factor is not high, needs to consume a large amount of energy, easily produces spark and the defective that can occur the temperature rise phenomenon along with the prolongation motor of machine operation time between the commutator of DC motor and brush.
Summary of the invention
In order to improve the DC motor power factor, energy savings, easily produce spark when avoiding starting DC motor between commutator and brush, and along with the temperature rise phenomenon can appear in the prolongation motor of machine operation time, the utility model provides a kind of energy saving dc motor.
This energy saving dc motor, comprise support, and be installed in stator and rotor in the support, it is characterized in that: around stator and epitrochanterian enamelled wire be: between copper cash and insulating varnish, set up one deck silver, this silver-colored thickness is the 1/4-1/10 of copper cash radius, and the coil on the stator and epitrochanterian armature winding are the silver-plated enamel insulated wire of 3-5 root to be wound up as one coiling form.
There is groove the outer end of the commutator segment of commutator on the rotor, and the length of groove is 1/3rd of commutator segment length, the width of groove be commutator segment width 1/3rd.
During this DC motor work, because the coil in the motor is silver-plated enamelled wire, reduce coil resistance, improved the induction factor of motor, reduced energy consumption, saved the energy; Again owing to opened groove at the commutator segment of commutator, can set up the better protection film when making the contacting of brush and commutator, reduced the temperature rise of motor and avoided commutator and brush between produce spark.
