  • Soft Starter 101: How do they work?

    Motor damage takes place as a result of mechanical wear and tear and huge inrush currents. Typically, VFDs help prevent wear and tear to mechanical components. VFDs slow starting and stopping of the drive train. A soft starter is a viable option if it is impossible to use a VFD with a motor. A soft starter minimizes the initial impact that a motor receives upon starting. The soft starter eases that impact once the operation stops. How do Soft Starters Work? Motor-driven applications rely on VFDs or soft starters. These devices prevent damage, or a significant amount of stress, to the

  • Do You Know How Critical Brushes are to a DC Motor?

    A DC motor has several components, and each serves an important role in ensuring its proper function and efficient performance. One of these is the carbon brush. We will find out more about its essential role inside a DC motor as explained below. Carbon Brush Basics In DC motors, a carbon brush plays a critical role. The brush makes sure the commutation process remains free from sparks. This contact is a sliding contact capable of transmitting electric current from static to the rotating part of a generator or electric motor. A single or several carbon blocks composes a brush. The brus

  • Advantages and Disadvantages of AC Generators

    Most commercial areas rely on AC to power a wide range of electrical appliances and pieces of equipment. AC results from the movement of the electrical charge through a medium. The direction of movement varies over time. This variation is not the case with DC since it only involves a single direction for its movement. AC Generator Basics An AC generator is a type of electromagnetic device, responsible for converting mechanical energy into electrical power, essential in electromagnetic induction applications. This device comes with a rectangular coil of wire, and this component rotates

  • What Role do Laminations Play in Electric Motors and Generators?

    In a DC motor, there is an iron core in a ring shape. Once the core rotates in a magnetic field, this generates a voltage in the coils that results in eddy current. In simpler terms, eddy currents are a type of magnetic loss. When losing power due to eddy current flow, this condition is called eddy current loss. Multiple factors impact the amount of power loss attributed to the flow of eddy current These include the magnetic material's thickness, the frequency of the EMF induced, and the density of the magnetic flux. What are Laminations in Motors? The resistance of the material in wh

  • Keeping us Safe One Sheet at a Time: MSDS

    A Material Safety Data Sheet is a vital element for anyone that works with a potentially dangerous material. It keeps the area safe, and when included with the right training, helps provide a safer and more eco-friendly work environment. What is a Material Safety Data Sheet? A Material Safety Data Sheet (MSDS) is a document that explains details about possible occupational hazards that might hinder the well-being and safety of workers. The documentation is not designed for consumers, but instead those who work around or with a particular substance that could be possibly dangerous.

  • Difference Between the Types of Explosion-Proof Motors

      It is important to choose the right type of motor to use on a site where there are explosive vapors or gasses nearby. In such locations where there is ignitable dust, be careful to select special motors to prevent hazards once an internal fault occurs during operations. In this article, we look into explosion-proof motors along with the differences between each. Basics on Explosion-Proof Motors The term explosion-proof refers to motors that approved for use in Class 1 locations. These sites have with potential explosive or ignitable vapors and gasses present throughout the p

  • Ultrasonic Signature Provide Early Warning of Mechanical Failure

    Ensure the proper condition of your equipment by conducting tests and checks providing accurate results. Ultrasonic signature is one these practical tests. Ultrasonic signature detects crucial issues, including insufficient lubrication or early problems with bearings. What Causes Ultrasound? Various factors result in ultrasound, including electrical discharge, impact, and friction. Whenever there is excessive friction in individual components, for instance, the equipment is likely to lose balance. Over time, the equipment may stop performing in an efficient manner. Or the equipment may

  • PdMA Tip of the Week: Drive Input Imbalances

    Current imbalances are sometimes referred to as a burglar alarm; problematic and need further diagnosis. However, imbalance at the inverter input under lightly loaded conditions is a normal phenomenon of the electrical circuit. The source of this current imbalance is often the connection of the power supply to the VFD, not to the motor itself. More specifically, the issue is the VFD’s full-bridge rectifier combined with subtle line voltage imbalances to the VFD. The VFD rectifier will draw from the input as necessary to supply the DC bus, which provides power through transistors to the motor
