Inverters

Inverters play a critical role in equipment sustainability and energy cost-savings for commercial and industrial applications. They are an essential part of electrical systems because you can easily adjust the frequency of the voltage supplied to your motors. This is extremely important when demand changes and you need a reliable system to help regulate needed adjustments.

Inverters

Inverters Control AC Power Frequency and Voltage

An inverter can freely adjust and modify the speed and torque of an electric motor.

They convert input AC power to DC power and then create AC power from the converted DC power using pulse width modulation (PWM) control.

It enables them to emit a pulsed voltage that is smoothed by the motor coil so that a sine wave current travels to the motor, allowing the motor inverter to control the speed and torque.

Control Modes of Inverters

  • V/f Control. V/f control is a method of motor control in which the voltage and frequency are proportional. It is also called the V/f characteristics. The motor speed is directly proportional to the applied voltage and frequency.
  • Vector Control. Vector control, also known as field-oriented control (FOC), is a control mode for variable-frequency drives (VFDs). A three-phase AC electric motor’s stator currents are identified as two orthogonal components displayed as a vector.

One component is directly proportional to torque, while the other is proportional to flux. Torque and change are measured in motor windings and used by the motor controller to produce the correct motor torque and flux.

  • Sensorless Vector Control. Sensorless vector control is a variation of vector control that does not require feedback from an encoder. The inverter uses the motor’s current and voltage output to correct the waveform. It results in finer speed control.
  • Vector Control with Encoder Feedback. Vector control with encoder feedback is a vector control variation that uses an encoder’s feedback. The encoder adjusts the output waveform and improves speed control.

Best Inverter Control Mode

The best inverter control mode for your application depends on several factors, including:

  • The type of motor you are using
  • The speed control range you need
  • The level of precision you require
  • The amount of torque you need
  • If you need the ability to reverse the motor’s direction

Benefits of Inverters

  • Energy-saving. An inverter AC motor drive is a key technology for reducing energy consumption in fan and pump applications. Inverter drives can reduce energy consumption by 20 to 50 percent compared to traditional on/off control or damper control methods by controlling motor rotation.
  • Precision speed control. Inverters can precisely control motor speed, making them ideal for applications that require slow speeds or frequent starts and stops.
  • Smooth acceleration and deceleration. An inverter motor drive can ramp up or down the speed of the motor smoothly and gradually, which is critical for applications such as escalators and conveyor belts to avoid dropouts of loads.
  • Improved process control. Because inverter drives can precisely control motor speed, they can also improve process control in packaging and materials handling applications.
  • Longer motor life. Inverter drives can extend the life of motors by reducing mechanical stress on the engine and bearings.
  • Reduced maintenance costs. The extended motor life and improved process control of inverter drives can lead to reduced maintenance costs.
  • Operator comfort. Inverter drives can help reduce noise and vibration in applications such as fans and pumps, which improves operator comfort.

Gear Reducers

Gear reducers are essential in many mechanical systems and can be found in everything from manufacturing plants to automotive engines. It can be used in many applications and industries, including machines with heavy or repetitive loads.

Gainesville Industrial Electric Co. offers a wide selection of quality gear reducers to help you get the most out of your machines and motors. We’ll go through the advantages of using one and the many available types. We’ll also advise on choosing the best gear reduction for your needs.

Gear Reducers

What is a gear reducer and what are its purposes

According to Market Prospects, industrial machines need a gear reducer to change the speed and power of the device. This is so it can meet the needs of different applications.  The reducer also helps to keep the machine running smoothly and efficiently.

A gear reducer is a type of mechanical device that is used to change the speed and torque of a machine. The device consists of two or more gears that are connected. The gear reducer’s size and capacity must match the application’s specific requirements.

There are several types of gear reducers, but the most common ones are helical, bevel, and worm. Helical gear reducers are the most popular type. They have a high-efficiency rating and low noise level. Bevel gear reducer is used in applications where space is limited. Worm gear reducer is used in heavy-duty applications.

Advantages of gear reducers

Some of the advantages of gear reducers include:

  • Increased Efficiency: One of the main benefits of using a gear reducer is that it can help increase the efficiency of a machine. When the speed and torque of a device are lowered, less energy is required to run it. This reduces operating expenses while also enhancing performance.
  • Improved Safety: Another advantage of gear reducers is that they can improve safety. When used properly, they can help to prevent accidents and injuries.
  • Extended Service Life: Gear reducers can help extend a machine’s service life. Reducing the speed and torque reduces wear and tear on the engine. This results in fewer repairs and more extended periods of operation between maintenance intervals.

Applications of gear reducers in various industries

Gear reducers are used in multiple industries, including food processing, manufacturing, mining, and construction. Below are some examples of how they are used:

  • In the food industry, gear reducers are used in conveyor systems to move food products from one location to another.
  • In manufacturing, gear reducers are used in assembly lines to move parts and components from one station to another.
  • In mining, gear reducers are used in conveyor systems to transport materials from the mine site to the surface.
  • In construction, gear reducers are used in cranes and hoists to lift heavy loads.

How to choose the right gear reducer for your needs

When selecting an electric gear reducer, it is essential to consider the application’s specific needs. The type of gear reducer, size, and capacity must match the machine’s requirements. The working environment will also influence the gear reducer’s material and construction.

For example, stainless steel or other corrosion-resistant materials must be made in wet or corrosive environments. Selecting a gear reducer with the proper efficiency rating and low noise level is also essential.

Maintenance and troubleshooting tips for gear reducers

To keep a gear reducer running smoothly, it is vital to perform regular maintenance and troubleshoot any issues that may arise.

Some tips for maintaining a gear reducer include:

  • Check the level of lubricant regularly and replenish it as needed.
  • Inspect the gears regularly for wear or damage.
  • Check the bearings and seals for wear or damage.
  • Clean the unit regularly to prevent the build-up of dirt and debris.

Here are some guidelines for resolving electric gear reducer issues:

  • If the unit is making noise, check for loose parts or excessive build-up of dirt and debris.
  • If the unit is vibrating, check for misalignment or wear.
  • If the unit is not operating correctly, check the lubricant level, type, and speed and torque settings.

Machine Design notes that when oil and grease lose their lubricating qualities, wear of the reducer soon follows.  Check the oil level monthly and change it according to the manufacturer’s schedule. Also, keep an eye out for metal filings in the bottom of the housing; they indicate abrasive wear.

These reducers are an essential part of many industrial machines and applications. You can ensure that they will provide years of reliable service by understanding how they work and how to maintain them properly.
