Servo motor power type, please say more details
At present, Taiwan Delta has introduced 380V power supply servo motor system, is the ASD-A2-L series, eliminating the transformer, more convenient.I wonder if I answered the question you wanted to know.
1. servo transformer can choose the traditional 3 phase isolation transformer (input 3 phase 380V, output 3 phase AC 200V)But the performance is stable and the price is more expensive.2. currently on the market have launched the 3 phase of electronic transformer, switching power supply with small volume, not much, but the wiring should pay attention to is the AC380V+N input line, the output is 3 200V; the price slightly cheaper than the 3 phase isolation transformer.
Servo motors are currently 200-220V power supply design, general power supply wiring principle: servo less than 750W driver can be directly connected to the single-phase AC220V can drive, nor will alarm.If the servo motor is more than 750W, the 3 phase AC 200-220V power supply is more stable and powerful.
