Variable Frequency Drives form an essential part of any manufacturing plant. Its continuous operation is necessary for maintaining a plant’s output, and any failure results in a chain reaction, effectively bringing the entire industry to a standstill.
In order to stay ahead in industry and to keep a company profitable, it is important to stay up to date with technology. Using the most efficient systems and products in manufacturing can help your company save money and save energy, which helps to not pollute the earth.
It’s a beautiful day outside. But the sun is high overhead and the temperature is going through the roof. As the air conditioning struggles to keep up, all the machinery, drives, panels are running, doing their job. Then, all of a sudden, everything shuts down. After investigation, you find that one of your drives overheated and shorted out the whole area. Heat dissipation in variable frequency drives (VFDs) or AC drives is an easy thing to overlook, but could lead to devastating downtime. Here are some tips on what to keep in mind when calculating how cool to keep drive enclosures.

When it comes to industrial configurations, one of the most important pieces of the puzzle is an energy efficient installation of variable frequency drives (VFDs). Also known as adjustable-frequency drives (AFDs) or AC drives*, VFDs should be a mainstay in nearly any manufacturing operation. After all, being energy efficient is not only more time efficient, but it also ultimately saves in many different costs.
Many motors are controlled by a valve that releases fuel as needed and a vane that regulates the air current flowing into the motor. In these cases, the speed of the motor is constant. These motors are often controlled by switching the motor on or off. Some other motors are two-speed motors and are slightly more efficient than the single speed motors. However, both of these types of motors are inefficient with regards to energy. Variable speed drives (VSDs) or adjustable speed drives help to eliminate this inefficiency.

Starting a motor can be compared to accelerating too hard after a red light turns green; everyone gets jerked around and everything goes flying. There’s nothing gentle about it and it can even hurt. With motors, it’s the same thing. If a motor starts up with too much power, too fast, it can be damaging. Soft starters are one way to prevent violent starts. Not only do they prevent damage, but they can save money and add efficiency as well.
Environmental concerns have pushed the world towards better energy efficiency. In the long run, energy saving practices can also save money. However, to actually reduce energy usage, new technology is needed. Equipment and machines in the manufacturing industry have had major improvements in recent years so that these practices are possible.
When TECO Electric and Machinery Company and Westinghouse Electric joined forces in the 1980’s to form TECO Westinghouse, they became a powerhouse for producing drives and motors. They manufacture a range of series with both AC and DC products. PanelShop.com offers a number of their AC drives and AC motors, and can guide you into choosing the right product for your application.
Technological advances all seem to be moving in the same direction. Everyone wants hardware and devices to be smaller, cheaper, and more effective. Drives and motors aren’t any different. Smaller drives and motors aren’t bonuses anymore; they are essential. But as these drives and motors become more compact, the inner workings of the devices have to keep up as well.
OEE stands for Overall Equipment Effectiveness. It is a measure in percentage of how well a production machine is utilized over a period of time. A rating of 100% means that a machine never breaks down, never runs slower than target time, and never produces a bad part. Although this is the goal, no machine is perfect, but having a way to measure how a machine performs gives us a way to determine whether changes to a machine are beneficial or not.
