Description

Motor and cleaner having the same The present disclosure relates to a motor and a vacuum cleaner including the same, and more specifically, to a vacuum cleaner including a motor with improved durability. Generally, a motor is a machine that obtains rotational force from electrical energy and includes a stator and a rotor. The rotor is configured to interact electromagnetically with the stator and rotates due to the force acting between a magnetic field and the current flowing through the coils. The motor may include a stator, a rotor arranged to rotate, a housing that accommodates the stator and the rotor, and a bearing that allows the stator and the rotor to be coupled at an accurate position so that the rotation of the rotor is stable. Motors can be used in various vacuum cleaners. For example, the motor can be placed inside the body of the vacuum cleaner to generate power. Electrolytic corrosion can occur in the bearings as the motor is used. When the motor is driven, switching occurs, and the current flowing through the stator can generate an induced current in the rotor. This induced current can travel from the rotor to the rotating shaft. Additionally, the induced current can be transmitted to the rotating shaft and to the inner ring, balls, and outer ring of the bearing, respectively. At this time, a potential difference is generated between the inner and outer rings of the bearing, which can damage the balls. In other words, galvanic corrosion can damage bearings and cause noise. Therefore, there is a recent demand to minimize galvanic corrosion of bearings. Additionally, there is an increasing demand for lighter motors for ease of use.
