Description

Technical Field

[0001] The utility model relates to the technical field of motors, in particular to a motor. Background Art

[0002] A motor is a device that converts electrical energy into mechanical energy. It uses an energized coil (that is, the stator winding) to generate a rotating magnetic field and act on the rotor to form a magneto-electrodynamic rotating torque. The motor is mainly composed of a stator and a rotor. The direction of the force movement of the energized wire in the magnetic field is related to the direction of the current and the direction of the magnetic flux lines (magnetic field direction). The working principle of the motor is that the magnetic field acts on the force of the current, causing the motor to rotate.

[0003] At present, in order to reduce the friction between the rotor and the casing during the use of the motor, a bearing is provided on the outer surface of the rotor to reduce the friction when the rotor rotates. In order to further reduce the friction and protect the bearing, lubricating oil is added to the bearing during use. During the operation of the motor, the lubricating oil will gradually be consumed, so the bearing needs to be regularly replenished with lubricating oil. When replenishing lubricating oil to the bearing in the existing technology, the lubricating oil is generally added to the filling hole, and then the lubricating oil is transported to the bearing through the operation of the machine. As a result, the lubricating oil cannot accurately reach the bearing position, resulting in unsatisfactory lubrication effect of the bearing. To this end, we propose a motor. Utility Model Content
