トロイダル トランスを選択する場合、トロイダルの電力 変成器 負荷の電圧と電流の使用状況に基づいて決定する必要があります。トロイダルの公称出力電流 変成器 is the output current at full load. When overloaded, the toroidal 変成器 can output more than 30% of the rated current. The overload capacity of toroidal 変成器s is very good, but the following two points need to be noted.
1.過負荷の機械および装置を起動するために使用されます
The current of some devices is rated during operation, but the current at startup is very large, sometimes exceeding 30%~50% of the rated current. For example, the overload capacity of an AC servo motor is usually designed to be 3 times the rated operating current. When the load starts, the current is large, which requires the toroidal 変成器 to be overloaded for a short time. Such a device with overloaded driving current is equipped with a toroidal 変成器, and the rated output current of the 変成器 needs to be considered to exceed about 20% of the rated current of the device. Due to frequent start-up overloads, the temperature of the toroidal 変成器 rises, and the long-term 変成器 life becomes shorter.
2.非過負荷機器に適しています
Many devices are designed with the maximum operating current in mind and the startup current does not need to be overloaded. For example, stepper motors are used as equipment power, and the operating current is the same as the starting current. When selecting a toroidal 変成器, it is not necessary to design a margin for the output current of the toroidal 変成器 as long as the output current is equal to or greater than 10% of the maximum current of the stepper motor driver. Stepper motors never have overload current. In more work environments, the power of stepper motors is variable. This requires that voltage and current parameters should be determined during structural design, and reasonable power should be given artificially. In fact, the power of aトロイダル トランスを選択する場合、トロイダルの電力 変成器 should be determined based on the voltage and current usage of the load.
