  • High-Efficiency Operation of a 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
  • 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.
  • Three Wire Control SJ100 L100 (.pdf)
    Sometimes it may be desirable to use a remote START/STOP pushbutton arrangement together with an inverter. This often occurs when a machine is being retrofitted or upgraded with the addition of a Hitachi inverter as a replacement for a motor starter
  • RF Pouch Isolates Wireless Car Entry/Starter Devices from Code Grabbers
    locks and starter motor. This evolving technology is generating new opportunities for customer service, for example rental companies are now able to remotely allow access to vehicles. There are also new opportunities for high tech thieves known as "Code Grabbers"
  • Say 'NO' to Safety Reliability Calculations (.pdf)
    is additional manufacturer responsibility due to the requirement of "functional safety.". This paper will review the effect of these changes in regard to a simple safety design strategy and will introduce readers to a new safety motor starter technology that is pre-certified to meet the new safety
  • Driven to Excel: Switched Reluctance Motor (SRM) Drives
    Switched reluctance motors (SRMs) have attracted considerable attention in industry over the past few years. Their unique capabilities (e.g., robustness, ease to closed-loop control, low-cost manufacturing, etc.) are among the determining factors for this renewed interest. Today, SRM drives
