Vertical PL-25C two-phase stepper motor automatic connection - This device is equipped with pulse input protection, and the shortest sequence control unit for safe start (including PL-25C), stop, and jump control has a human-machine interface, making the system more stable and reliable. It has been widely used in vertical PL-25C two-phase stepper motors, three-phase stepper motors, and three-phase stepper motor drive units. The parallel configuration of the device can ensure stable operation of the motor in a short period of time and improve stability, but the overall performance of the system is more reliable, and the thermal balance of the system can improve the cooling efficiency of the system.
The temperature rise characteristics of the machine will directly affect the operating characteristics of the motor. Firstly, the change in current should be controlled through temperature changes to improve the operating performance of the motor, and the safe operation of the motor should be ensured.
The power level is a unit of motor insulation and operation that achieves electrification at the rated operating voltage of the switch. From the relevant working conditions of power capacitor banks, it can be seen that the insulation characteristics of motors with the same voltage level can allow the maximum operating voltage and current to reach 600 A. The average ultimate working voltage of motor insulation is usually lower than 40 V. When appropriate control measures are taken, it can be ensured that the motor has a "long-term operation" load at the rated operating voltage. Due to the consideration that the rated current ratio of high-voltage cables is usually 1 A. The outgoing direction of high-voltage cables is generally horizontal, and shielded wires can be used in both vertical and horizontal directions. However, shielded cables are generally set in a different direction from high-voltage wires, and they can be converted into a mesh structure. In addition, shielded cables can also be directly used with power cables (low-frequency shielded cables). The selection of power cable specifications is generally based on the lack of design of circuit breakers that do not affect the components. However, if the installation is not standardized, the high-voltage connection during the occurrence of faults can cause short circuits, becoming the most common problem. Today we will discuss the selection process of high-voltage cables to help
