From ceiling fan installation to smoke detectors and electrical water heaters, our team of licensed electricians can tackle it all! Another area that our team of electricians specializes in is electrical motors. Since electrical motors convert electricity into mechanical or kinetic energy, they have many different applications. Keep reading to learn more about the basics of electrical motors, common applications and repairs.

Electrical motors are commonplace in many personal, household and industrial products such as power tools, watches, disk drives and batteries. Essentially these motors are machines that come in all different sizes and are used to transmit electricity into mechanical or kinetic energy. We often take electricity for granted when we switch on our lights or our television. In fact, it is the behind-the-scenes work of electrical motors that causes the instant conversion of electricity into energy which immediately powers our devices.

As previously mentioned, electrical motors are used in so many of our personal and household items. We rely on them to track time, grind coffee, wash clothes and keep us warm. Our world would be much different without electrical motors. Outside of our homes and personal lives, electrical motors play a much larger role. Electrical motors are used in all types of commercial industrial equipment including pumps, mills, refineries and more. The significant impact of electrical motors extends all throughout the oil & gas, energy, mining and water industries.

Like most electrical items, electrical motors require regular maintenance and repairs. Although electrical motor repairs may seem intimidating to some, a licensed electrician can handle the repair and maintenance of most motors in personal and household items.

LED fixtures, such as

With energy consumption that is less than half of what 150-watt LED parking lot light that is a direct replacement for 400-watt metal-halide (MH) fixtures. That’s 250 watts less for the same amount of light!

The average price of electricity per kilowatt-hour (kWh) is 12 cents. To figure out the monthly cost of running 25 LED parking lot lights for 11 hours per day, use this formula: (combined wattage x monthly hours of use)/1,000 x price per kWh. For 25 LED lights, (3,750 x 330)/1,000 x .12) the total would be $148.50 per month or $1,782 per year.

When the same formula is used for 400-watt MH fixtures, the monthly cost is $396, and yearly cost would be $4,752. So, in this situation, switching to LED fixtures would save approximately $3,000 per year. When coupled with the savings on maintenance, LED fixtures can save $6,470 per year. At that rate, the cost of 25 $340 LED fixtures would be recouped within two years.

Left: LED wall packs; Right: HID wall packs

Unlike LED fixtures that light up instantly, HID parking lot lights require a warmup period of up to 10 minutes before they reach full brightness. They also can’t be turned immediately back on after being switched off; this is called restrike time, and it can take up to 15 minutes before they can be turned on again. Attempting to power on the lights before the bulbs have cooled can damage a fixture’s components and cause the HID bulb to fail sooner.

HID lamps consist of a ballast and a quartz tube that contains gas, metal salts, and two tungsten electrodes. In order to create light, an electric arc passes from one electrode to the other through a gas (most commonly mercury, metal halide, or sodium). The mercury used in this process is dangerous if enough is inhaled or released into the environment. If an HID bulb bursts, all contents should be put into a sealed container or sealed bag and taken to a recycling center or hazardous waste facility. If HID fixtures are used indoors, wall packs and canopy lights, are used indoors, the possibility of ultraviolet (UV) radiation exposure should be taken into consideration. HID bulbs emit a substantial amount of UV radiation, but an outer glass envelope prevents the radiation from escaping. However—according to the FDA—”If the outer bulb breaks and the inner tube continues to operate unshielded, intense UV radiation is emitted. UV exposure at this level can cause eye and skin burns, as well as blurred or double vision, headaches, and nausea.” The UV light from an HID bulb with a broken envelope can also lead to discoloration of items and fabric. LEDs emit little to no UV radiation.

In short, LED lights are a better alternative to HID parking lot lights. They offer a great deal in the way of savings, longevity, maintenance reduction, brightness, color, and safety. While it may take a short amount of time to recoup the price of switching to LEDs, all of their qualities make it easy to see why so many businesses have started the process.

We’re finally through another summer in Texas. Our air conditioners are being turned off for the first time in months, and we’re all looking forward to watching that power bill drop. Now that your electrical system is under less stress, it’s the perfect time to make sure that the system is working the way it should.

Nobody should go years without performing maintenance on their vehicle. It just makes no sense to throw away the investment you made on a vehicle. And yet, people regularly go years and years without having their electrical system inspected on their home. Typically you spend a lot more on your home than a vehicle, yet both can be dangerous if you don’t do regular maintenance!

With this in mind, I wanted to share some important Electrical System Maintenance with you that can help keep you safe and even keep your power bill low! Keep in mind that the things I’m going to share with you aren’t really things you can do on your own; you should always contact a Licensed Dallas Electrician to implement any of these tips.
