[0002] The casing type series motor is a motor form commonly used in vacuum cleaners. It is generally composed of a casing, a stator, a rotor, a stator winding, and a rotor winding. The casing is generally made of metal. Because the metal material conducts electricity, the metal casing The electrical safety performance is poor, and the metal casing is difficult to process and difficult to shape. The metal casing needs to be stamped and formed many times during the production process, resulting in large processing errors in the casing size and large motor vibration. The motor occupies a large space in the vacuum cleaner, which cannot meet the needs of use

The invention discloses a series excited motor for a dust collector. The series excited motor comprises a shell, a stator and a rotor are arranged in the shell, The rotor comprises a rotating shaft, the rotating shaft is sleeved with a rotor core and a commutator, a rotor winding is arranged on the rotor iron core, the stator comprises a stator iron core, a stator winding is arranged on the statoriron core, the shell is made of plastic, a stator impeller and a carbon brush are connected inside the shell, a torsion spring is connected onto the stator impeller, one end of the torsion spring isconnected with the stator impeller, and the other end of the torsion spring abuts against the carbon brush to enable the carbon brush to abut against the commutator. The shell is easy to shape and process, the safety performance of the motor is improved, the processing error of the shell can be effectively reduced, the vibration of the motor during operation is reduced, and the space occupied by the motor in the dust collector is reduced.
Description
technical field [0001] The invention relates to the technical field of motors, in particular to a series motor for a vacuum cleaner. Background technique [0002] The casing type series motor is a motor form commonly used in vacuum cleaners. It is generally composed of a casing, a stator, a rotor, a stator winding, and a rotor winding. The casing is generally made of metal. Because the metal material conducts electricity, the metal casing The electrical safety performance is poor, and the metal casing is difficult to process and difficult to shape. The metal casing needs to be stamped and formed many times during the production process, resulting in large processing errors in the casing size, large motor vibration, and existing The motor occupies a large space in the vacuum cleaner, which cannot meet the needs of use. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a series motor for a vacuum cleaner, which can ...
