Heating can be very common within stepper motors, some heating is normal, however this heat should be kept at a safe level. Why does the stepper motor heat up? Often this happens due to the internal core and windings of the motor. The resistance of the winding will cause power loss, which is often called copper loss. If the current is not a standard DC it may also experience harmonic loss.
The stepper motor may also have heat changes in response to the speed of the motor. The motor will often maintain constant speed under low speeds that are consistent. If the stepper motor is subjected to various speeds the copper loss may increase and heat the motor.
To reduce the step motor from heating the easiest thing to do is reduce the copper loss. This is done by reducing the resistance and the current, the easiest way to do this is to find a motor with a low resistance and current. Keep the motor running at consistent speeds, and make sure you select the proper step motor for your application.
This past June the Fluke Company made a generous donation of twelve new digital multimeters to Everett Community College located in Everett, Washington. The company is based out of Everett, Washington and has made multiple contributions to institutions in the past. The multimeters were sent to the engineering department of the community college and will be used in a number of different class related projects.
Engineering instructor, Matthew Parsons, of Everett Community College mentioned it is more useful to have a digital multimeter in an electrical engineering class than a pencil. The multimeters are used to measure functions such as voltage, current, temperature, and resistance.
Donations like these help drive students to pursue careers within engineering, and possibly with the Fluke. Fluke, being a leader in test equipment and software, realizes it is important to provide the youth with quality tools. The company knows the products are going to good use.
Soldering is a tool that is used by professionals and hobbyists alike. It is defined as joining metals by fusing the alloys which have low melting points. This type of skill is often used in electrical and electronic work, it is a skill that is easy to practice and is very useful. Use the following tips to prepare yourself for soldering.
Before you begin soldering it is important to “tin” the tip of the soldering iron. This is coating the soldering iron tip with a coat of solder to aid in heat transfer. Next will be time to warm up the soldering iron. Make sure the iron heats up completely, this is very important with new soldering irons, since there may be a layer of coating on the tip to prevent corrosion.
The next step is to have an open, clutter free work area. It is important to have proper air flow, no loose clothing on, and a moistened sponge for cleaning the soldering tip. Now you will want to coat the tip in solder, making sure to coat the entire tip. Keep in mind you will be using a good amount of solder so keep more close and handy. Once the soldering tip has been coated with solder wipe the tip with the wet sponge to remove any flux residue. This is best done quickly so the residue has no time to harden and stick to the solder tip.
Tinning must be done every time the soldering iron tip is changed or a new one is being used. This will make it easier for heat to transfer from the iron to the solder. Soldering will go quicker and you will be much more precise.
PRNewswire has reported the Industrial Designers Society of America(IDSA) has honored Fluke Corporation with a Gold Award in its International Design Excellence Awards(IDEA) program. This international competition honors design excellence in strategy, products, concepts and research, and more. The new 37x/38x clamp meter from Fluke won the award in the Commercial and Industrial Products category.
Fluke was created in 1948 and has been a leader in growing a technology market that requires troubleshooting in service and manufacturing industries. Fluke products are used in a number of manufacturing plants, offices, hospitals and homes of hobbyists. Professionals in many fields, including; electricians, plant engineers, and HVAC technicians, use Fluke products including digital multimeters, and variances of the clamp meter.
The Fluke clamp meter answers the ergonomic issue clamp users have had for years. How to read the display easily, while positioning the clamp. Fluke has fixed this problem by decoupling the display from the meter making it easier to read. The new clamp meter is sure to be a great addition to many professionals, in many different fields.
