  • Selecting The Right Motor Starter Option
    It's estimated that there are more than 300 million electrical motors installed worldwide. Application requirements necessitate motor starters in many of those installations. Of the various motor starter options, which is the best fit for your application? This white paper provides the pros
  • High-Efficiency Operation of an Hybrid Electric Vehicle Starter/Generator Over Road Profiles
    Efficient operation of induction motor starter/alternator systems is an important part of the power-management function that is required in the self-contained vehicular environment. However, the nonlinear dynamics of the induction motor [1], parameter sensitivity to environmental factors, load
  • Understanding Electronic Motor Drives
    . For instance, take a simple application of a fixed-speed motor driving a fan. Replacing a three-phase motor starter with variablefrequency drive (VFD) permits the fan to operate at variable speeds. One benefit is energy savings,
  • Not By MOSFETs and Processors Alone: Passive Components Also Critical to Advanced Motor Control
    The internal-combustion car historically had only one high-current electric motor: the starter. This 12-V/100-A (typical) unit does not need sophisticated control, as it is just an on/off, "give it the full 12 V DC and let it rip" motor. The few other motors were small and easily controlled
  • Virtual Engineering Lab for Motor Testing and Development
    for fully interactive control of actual system hardware. To understand the potential benefits of the VE-LAB, consider one example application: the development of a high-efficiency starter/generator for hybrid electric vehicles. With an induction motor starter/generator connected into the VE-LAB
  • What Is Your Ideal Overload Relay?
    Choosing which relay to use for overload protection depends on the specific electric motor starter application.
  • Motor Starters
    Full-voltage starters (manual and magnetic) apply full voltage directly to motor terminals. Two other types, combination and reversing starters, consist of a starter, usually magnetic, with added functions. Some machines or loads may require a gentle start and smooth acceleration up to full speed
  • Motor Starters
    Single-speed squirrel-cage motors have starters that fall into two categories: full-voltage or across-the-line starters; and reduced-voltage starters. Full-voltage starters (manual and magnetic) apply full voltage directly to motor terminals. Two other types, combination and reversing starters
