What Is The Maintenance Work Of DC Motor Rotor?

DC motor rotor through the current and stator magnetic field interaction to complete the conversion of electrical energy into mechanical energy rotation. The rotor is one of the important components of DC motor, its maintenance work is essential, the following is a detailed explanation of the DC motor rotor maintenance work are what

1、Check the armature core
(1) The core should be kept clean and free of debris, oil and dust from brushes.
(2) The core should be kept fixed and not slipped or deformed.
(3) Ventilation grooves should be cleaned regularly and leveled.
2、Check the armature coil
(1) Whether the slot wedge is tightened
(2) The coil surface should be free of defects and damage, such as burns, wear or breaks.
(3) Measure the insulation resistance of the armature coil to the core with a 1KV shaking table, it must be at least 0.5 megohm.

3、Check the armature tying wire
(1) The tied wire should be neat and free from looseness.
(2) Solder without melting open welding phenomenon.
(3) The insulation of the pad of the tied wire should be intact.
4、Check the fan
(1) The fan should be neat and tidy, without oil and dust.
(2) The rivets should be secure and the blades should not be broken or deformed. Assess the fan for obvious damage by tapping the blades with a small hammer and listening to the sound produced.
(3) The balance block should be stable and free of movement.
