How does DC motor maintain?
Short-term maintenance
Optimal configuration of the number of carbon brushes
The number of carbon brushes in the DC motor should meet the load capacity specified in the national standard. According to the requirements in "Technical Conditions of Z Series Medium-sized DC Motors" ZBK23 001-89, DC motors for metal rolling mills should be able to withstａnd the following continuous overloads: ①Continuous operation with 115% rated load at rated voltage and speed; ②At rated voltage After continuous operation at speed and load, run at 125% rated load for 2 hours.
For example, a Z400-4B DC motor has a rated power of 400kW and a rated current of 715A. There are 4 brush holders in the motor, and 6 carbon brushes are installed on each brush holder. The surface size of the carbon brush is 25mm×32mm. Then the carbon brush design work area (cm2) is:
The surface area of a single carbon brush × the number of carbon brushes on each brush holder × the number of motor pole pairs =
25×32×6×2=9600mm2=96cm2
Under the rated load of 125%, the operating current density of the carbon brush is: 715A×l.25÷96cm2=9.3A/cm2, which is within the range of the theoretical optimal operating current density of the carbon brush from 8 to 12A/cm2. But in actual use, the maximum load current of the motor is only 600A, that is to say, the maximum working current density of the carbon brush of the motor is: 600A=96cm2=6.25A/cm2. It is much lower than the lower limit of the theoretical optimal working current density of carbon brushes, 8A/cm2.
If the working current density of the carbon brush is too small, it will cause linear and groove-shaped nicks on the surface of the motor commutator, which shortens the turning treatment cycle of the commutator and shortens the service life of the motor. On the contrary, if the working current density of the carbon brush is too large, it will cause the surface of the carbon brush and the commutator to heat up, and the commutation spark will be large. After adjusting the number of carbon brushes as shown in Table 2, the current status and groove-like nicks on the surface of the commutator are effectively avoided.
