Sale discount house motors， It is easy to cause wear and tear in the process of motor operation. Under such circumstances, how can we reduce the occurrence?For example, a DC motor is a motor that converts direct current energy into mechanical energy.Because of its good speed regulation performance, it has been widely used in electric drive.Dc motors can be divided into permanent magnet, separate excitation and self-excitation, among which self-excitation can be divided into shunt excitation, series excitation and compound excitation.When the DC power supply is supplied to the armature winding through the brush, the n-pole lower conductor on the surface of the armature can flow the current in the same direction. According to the left-hand rule, the conductor will be subjected to the counterclockwise torque.Some of the conductors below the S pole of the armature surface also flow current in the same direction, and the conductors will also be subjected to counterclockwise torque according to the left-hand rule.
In order to ensure the service life of DC motor, we must pay attention to the phenomenon of equipment wear when using. In order to ensure the safety coefficient and achieve greater efficiency of the equipment, it is suggested that we learn the method to reduce the wear of DC motor.
1. Main manifestations of failure after long-time use
The vibration is enhanced during use.The main reason for this phenomenon is: the internal parts of the DC motor case wear too much or have been damaged.
2. Parts that may be damaged: gear tooth surface is worn, gear tooth is broken, axle hole or keyway of gear wheel is worn;The screw hole in the bearing hole is easy to fail because of wear;Shaft surface, keyway is also prone to wear due to long use time.
3. Solution skills: Not all repair departments have the technical strength to repair according to this method, but if the large equipment, can find the repair point to repair parts, for the overall cost of the enterprise will be greatly saved.
