The China high voltage dc motor factory tells you the work requirements of the DC motor.
The work requirements of DC motors are discussed from both the system and the requirements of motors. In order to ensure productivity and processing quality, DC motors require good rapid response characteristics in addition to high positioning accuracy. That is, the response of the tracking instruction signal is required to be fast, because when the CNC system is started and braking, it is required to increase and decrease the acceleration sufficiently to shorten the transition time to the system and reduce the profile transition error. The working principle of the DC motor was mentioned above. Now we follow the miniature electric machine factory to understand the working requirements of the DC motor.
Requirements of DC motors for systems
1, wide speed range
2, high positioning accuracy
3, there is enough drive stiffness and high speed stability
4, rapid response, no overtones
5, low speed large torque, strong overload ability
In general, the DC motor driver has an overload capability of more than 1.5 times in a few minutes or even half an hour, and can overload 4 to 6 times without damage in a short period of time.
6, high reliability
