Quando si seleziona un trasformatore toroidale, la potenza del toroidale trasformatore deve essere determinato in base alla tensione e all'utilizzo della corrente del carico. La corrente di uscita nominale di un toroidale trasformatore is the output current at full load. When overloaded, the toroidal trasformatore can output more than 30% of the rated current. The overload capacity of toroidal trasformatores is very good, but the following two points need to be noted.
1. Utilizzato per avviare macchinari e attrezzature sovraccaricati
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 trasformatore to be overloaded for a short time. Such a device with overloaded driving current is equipped with a toroidal trasformatore, and the rated output current of the trasformatore 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 trasformatore rises, and the long-term trasformatore life becomes shorter.
2. Adatto per apparecchiature senza sovraccarico
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 trasformatore, it is not necessary to design a margin for the output current of the toroidal trasformatore 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 aQuando si seleziona un trasformatore toroidale, la potenza del toroidale trasformatore should be determined based on the voltage and current usage of the load.
