Static frequency converter.<\/h2>\n\n\n\n

Frequency converters or 50Hz to 60Hz converters are pretty popular in industrial environments. That’s because they can change the supplied frequency of voltage and protect expensive industrial equipment. Some applications also need 400Hz or 60Hz to 50Hz converters. While keeping that in mind, let’s explore more on static frequency converter 50Hz to 60Hz in particular. The solid-state unit uses Pulse with modulation (PWM) technique to generate the desired frequency. On this page, we will see working, advantages, and types of hertz converters. We hope this will help you decide to select the right style and capacity.<\/p>\n\n<\/div><\/div><\/div>\n<\/div>\n<\/div><\/div>\n\n

What is a frequency converter?<\/h2>\n\n\n\n

A frequency converter, sometimes known as a power frequency changer, is a device that transforms 50hz to 60 Hz or 50Hz to 400 Hz output power. There are several types of power frequency converters, including rotary converters and solid state frequency converters. Rotary type system runs a motor using electrical energy. The incoming alternating current (AC) is converted to direct current using solid-state frequency converters (DC).<\/p>\n\n\n\n

You will come across the need to modulate the frequency of current for industrial applications. Frequency converters are, described, Hertz converters. The frequency converter transforms a fixed-frequency, fixed-voltage sine-wave power (line power) into a variable-frequency, the variable-voltage output used to adjust induction motor speed. Frequency converter 50Hz to 60Hz is the most commonly used unit of all configurations.<\/p>\n\n<\/div><\/div><\/div>\n<\/div>\n<\/div>

Why do you need a frequency converter?<\/strong><\/h2>\n\n\n\n

When working on applications with power load, you will need to use a power frequency converter. For example, many machines imported to Asian or Middle Eastern countries from the USA run on 60Hz. But, the utility power supply in most of Asia and the Middle East is 50Hz. Hence, to start those machines, one needs a 50Hz to 60Hz converter. <\/p>\n\n\n\n

Frequency converter 50Hz to 60Hz is commonly used in UAE, Oman, Qatar, Saudi Arabia, & Kuwait. Defense, Aviation, Marine, and Manufacturing industries need Hertz converters.<\/p>\n\n<\/div><\/div><\/div>\n\n

Other than above, there are several reasons which justify the use of a frequency converter. Some of the most prevalent reason behind investing in it are as follow.<\/p>\n\n\n

For energy saving.<\/h3>

However, there are situations where the lights and resistance heaters don’t be mindful of the incoming power frequency. If you are using a resistive load, you will not necessarily have to go with frequency conversion. However, it will still be possible for you to save money. In industrial applications, the fundamental function of a static frequency converter is to save energy. Energy savings can be significant when a pump’s speed is controlled rather than flow through throttling valves.<\/p>\n\n\n\n

In addition to conserving energy, the impeller, bearing, and seal life is also substantially enhanced. For example, a 20% drop in speed can result in a 50% reduction in energy use. The next sections discuss how to reduce speed and save energy as a result.<\/p>\n\n<\/div><\/div>\n\n

Frequency converters, which come in various configurations, are the most efficient way to adapt pump and fan flow rates to system needs. It transforms conventional plant power in 220V and 50Hz to customizable voltage and frequency to power an AC motor. The frequency determines the motor speed supplied to an AC motor. For some motors, you might need a 60Hz to 50Hz converter.<\/p>\n\n\n\n

AC motors are typically identical standard motors that may be connected to an AC power line. Even if the inverter fails, the function may be maintained by integrating bypass starters. Frequency converters also provide the added benefit of extending the life of bearings and pump seals. The pump is not subjected to any greater pressures than necessary since just the pressure required to meet system requirements is maintained in the pump. As a result, the components have a longer lifespan. The same benefits apply to fans controlled by solid state frequency converters, although to a lesser extent. Also, we can use stabilizers and regulators.<\/a><\/p>\n\n<\/div><\/div>\n\n

Other benefits of frequency converters.<\/h3>
<\/span>\n <\/div><\/div>
\n\n

Frequency converters can give other benefits in addition to energy savings and greater process control:<\/p>\n\n\n\n

  • We can use a static converter to manage process temperature, pressure, or flow without a separate controller. The frequency converter is interfaced with driving equipment using appropriate sensors and electronics.<\/li>
  • Lower running speeds result in longer bearing and motor life, which reduces maintenance expenses.<\/li>
  • The maintenance of throttling valves and dampers and all associated controls are eliminated when these devices are removed.<\/li>
  • It is no longer required to use a soft starter for the motor.<\/li>
  • In a liquid system, a controlled ramp-up speed helps prevent water hammer issues.<\/li>
  • A frequency converter’s ability to limit torque to a user-defined level helps safeguard driven equipment that can’t handle too much torque.<\/li><\/ul>\n\n\n\n

    If these benefits are appealing, you may consider getting a frequency converter for the industrial applications that you are currently working on.<\/p>\n\n\n\n

    Many specifiers request comprehensive information from manufacturers to achieve maximum efficiency and dependability. They next conduct a thorough investigation to decide which system would provide the highest return on investment. It might include efficiency, needed maintenance, diagnostic capabilities, and basic operating characteristics of the frequency converter.<\/p>\n\n<\/div><\/div>\n<\/div>\n<\/div><\/div>\n\n

    What are the types of frequency converters?<\/strong><\/strong><\/h2>\n\n\n\n

    There are two main types of frequency converters available for you to use. They include static frequency converters and rotary frequency converters. Let’s deep dive and explore what these differences are.<\/p>\n\n\n\n

    Static frequency converter.<\/h3>\n\n\n\n

    Static frequency converters are power converters that convert incoming AC power to DC power (rectifier stage) and then to the appropriate AC frequency and voltage. Where noise, compactness, accuracy, or flexibility are essential, static frequency converters are excellent. These units are naturally silent, making them perfect for use in offices and laboratories. Noise levels are typically less than or equal to 65 decibels (dB). Single-phase to three phases and three phases to single-phase is the most common phase conversions.<\/p>\n\n\n\n

    Static frequency converters are not particularly successful at beginning motor loads because of the regular motor starting surge current necessary to start motors. To begin to run, motor loads require a hefty kick (6 to 10 times full load amps). This motor starting spike, also known as “locked rotor,” current, is very temporary, lasting only a few milliseconds at its peak before decreasing to normal operating current in about a second. On the other hand, a static frequency converter doesn’t “know” that this big spike will only last milliseconds, so it shuts down to protect itself. The overload capacity of the converter must be matched to the motor starting current. Thus, it resulting in a substantial oversizing of the converter.<\/p>\n\n\n\n

    Airports require a frequency converter 50hz to 400Hz as a ground power unit (GOU). The advantage is that the same unit can use a 60Hz to 50Hz or 50Hz to 60Hz converter with setting change. Temperature and humidity are additional factors that affect static converters. They are, in essence, air-conditioned and are not tolerant of harsh conditions, such as salt fog. They typically last for ten years of uninterrupted service.<\/p>\n\n\n\n

    Rotary converter.<\/h3>\n\n\n\n

    Incoming AC is converted into rotational mechanical power, sent to a generator, which transforms the mechanical power into electric AC output power. Electrical power measurement is in Kilowatts (kW) or Kilovolt-Amperes, whereas rotary power is measured in Horsepower (HP). This procedure necessitates frequency, voltage, and\/or phase conversion. The driving motor and generator are connected in a variety of ways in motor-generator systems. The rotary frequency converter is always ideal for motor loads.<\/p>\n\n\n\n

    Belt coupled converters are the most straightforward and least expensive technique since they employ drive belts and pulleys to transmit energy from the motor to the generator and alter the frequency by changing the pulley ratio. Some clients are concerned about drive belt lifetime, yet drive belts do not fail in practice when correctly designed and fitted.<\/p>\n\n<\/div><\/div><\/div>\n<\/div>\n<\/div>
