TDA2030 single power connection circuit diagram
TDA2030 is a Hi-Fi amplifier integrated block used in many computer active speakers. It is easy to connect and affordable. The rated power is 14W. The power supply voltage is ± 6 ～ ± 18V. The output current is large, the harmonic distortion and the crossover distortion are small (± 14V / 4 ohm, THD = 0.5%). Has an excellent short circuit and overheat protection circuit. There are two kinds of connection methods: single power supply and dual power supply: single power supply connection

The single groove blanking process of motor blanking is a kind of blanking process relative to double blanking. Motor fixed, Rotor Core punching using single groove punching process, its mold design, manufacturing are relatively simple, suitable for small batch, variety of production, has the characteristics of low cost, fast change. With the development of advanced punching machine, production efficiency continues to improve, the single punching process is also developing rapidly. For the large motor, because of the cost of the duplex die and the equipment capacity, the single groove is also used. Another advantage of single groove punching is the consistency of groove size. Compound die is the same punch, stator or rotor groove completed at one time. How many slots correspond to the same number of punches, punch size to achieve complete has always been some difficulties: single slot punching is by the same punch to complete all the slots, groove consistency is better.
Stator and rotor laminations are an important part of motors and generators. For large-size and small-batch punching sheets, we usually use the notching method to produce them. The advantages of notching are that the cost of the notching die is low and the production cycle of the notching die is short. It is suitable for producing large size laminations, usually the outer diameter is from 500mm-1250mm. The slot size is more accurate than Laser Cutting.
