1. Due to the large moment of inertia of the air compressor, the capacity of the inverter should be determined according to the specific working conditions and the operating current of the site. 2. The pressure sensor should be in the pressure change is not relative...

1. Why can the rotation speed of the motor be changed freely? The unit of motor rotation speed: r/min the number of rotations per minute, can also be expressed as rpm. Example: 2-pole motor 50Hz3000 [r/min] 4-pole motor 50Hz1500[r/min] Conclusion: The rotation of the motor ...

The presentation of inverters has brought a revolution to industrial automation control and motor energy saving. Industrial production is simply inseparable from the inverter, even in the daily livelihood, elevators, inverter air conditioning has become a part of the insistence, inverter from the beginning into all corners of production, subsistence. However...

1.SB200 fan pump special inverter, widely used in textile, printing and dyeing, washing, cable, packaging, machinery, ceramics, constant pressure water supply, constant temperature control or various OEM. 2.HG1000 high-performance light-load intelligent inverter ...

What is a frequency converter? Variable Frequency Drive (VFD) uses inverter technology and microelectronics to change the operating power frequency of the motor to control the power control unit of the communication motor. The inverter is mainly composed of rectifier (from communication to DC), inverter, inverter (from DC to communication) ...

When the inverter current is too large, exceeding the limit value of the inverter, the maintenance circuit will produce action, so that the inverter trips and stops, and the phenomenon of repairing such inverter can be divided into energized ...

What is a frequency converter? The inverter is a converter that converts the communication electricity with fixed voltage and frequency into the communication electricity with variable voltage and frequency, which is called the inverter. It is mainly used in the local demand for speed regulation, and its output not only changes the voltage but also changes the frequency together; The soft engine is really ...

1. The contact screen all-in-one machine adopts the new contact identification technology, and the user only needs to touch it lightly on the contact screen without passing the pressure sensing to complete the operation. Care must be taken not to use too much force or sharps to scratch the surface of the contact screen. ...

If the three power cables of the servo motor (SM) are not connected correctly, there may be no alarm in the static state. But as soon as the motor is operated manually or actively, the motor jumps off or starts to flutter, such as jumping when the speed is added too high, the system will issue generalized faults, etc.

The following four steps are very important for the commissioning of the inverter with the machine (i.e., connected to the motor) and no-load (i.e., the motor without load). (1) Set the power of the motor, the number of pole pairs, and check the operating current of the inverter. （ ...

1. Select the inverter according to the load characteristics Second, when selecting the inverter, the actual motor current value should be used as the basis for the selection of the inverter, and the extra power of the motor can only be used as a reference. Secondly, it should be fully considered that the output of the inverter contains higher harmonics, which will form the power factor of the motor.

How does the hovering function of the inverter work? When the speed of the asynchronous motor is 0, the encoder response is meaningless, and it needs to be converted to V/F control, and the frequency is set to 0; The voltage is set to 0 speed at which the motor promises to withstand the current at the moment ...

In some fields, the use of inverter to control the motor will present the problem of leakage, and the leakage voltage ranges from tens of volts to 200 volts. According to the inverter control motor ...

On April 15, 2011, the "Century Tour of China's Automation Industry (CAIE2011)" was held in Beijing, and Sunland inverter was once again re-elected as "China's well-known brand of domestic inverter". Dr. Chen Bin, President of Continental Hope Group and Chairman of Hope Sunland Technology Co., Ltd., personally ...

The wearing parts of the driver mainly include electrolytic capacitors for filtering and cooling fans, and their service life is closely related to the environment and maintenance of the operation. Depending on the operating moment, the user can determine whether a wear part needs to be replaced. Cooling ...

Now, the frequency conversion speed regulation system has been widely used in the industrial production of various small and medium-sized enterprises. This is all due to our ability to provide accurate speed control and complete stepless speed regulation. Therefore, it can easily control the ascent and descent of mechanical transmissions, traverse ...

Hope Sunland Technology Co., Ltd. is a national key high-tech enterprise dedicated to the research and development of high, medium and low voltage frequency conversion technology and the design, development, production, sales and service of related products.

There are many special faults, which come and go, looming, making it impossible to judge and deal with. At this time, you can clean the circuit board with water or alcohol, and brush off the dust and rust on the circuit board with a soft brush, especially pay attention to the solder joints are dense, and the circuit near the 0 volt copper layer is also ...

The motor is able to rotate, but the operating current exceeds the rated value, which is called an overload. The fundamental reflection of overload is that although the current exceeds the rated value, the fluctuation of the excess is not large, and it generally does not constitute a large inrush current. 1. The main reason for overload (1) Excessive mechanical load ...

The wiring interval between the motor and the inverter is too long, causing the new motor to catch fire Burn two new motors in a row! The output current and voltage of the inverter are balanced, the input voltage is balanced, the current is unstable, the fluctuation is 20%-50%, the inverter is burned off by a short circuit between 35Hz turns, the grid voltage is very stable, 720V, ...
