DRIVES

AC & DC drives are common choices among companies seeking to improve efficiency and control of their applications.

Each drive type offers users unique capabilities and an abundant array of control options to vary the supply of horsepower and speed to your machine; additionally, both AC & DC drives have a history of proven results.

Before choosing a drive, you must consider several factors: application, environment, horsepower requirements, sequencing, and others. Though these drives are similar, each has its respective characteristics and applications.

When the time comes to choose a suitable drive, we can help. We are a leading supplier of AC & DC drives from top manufacturers.

In addition to supplying AC & DC drives, we can also provide shop and field services to support these products.

LEI Drives

AC DRIVES

AC drives control the speed of electric motors in an energy-efficient way. They have solid-state inverters that adjust the voltage and frequency needed to vary speeds. To maintain a constant relationship between voltage and frequency, AC drives rely on the volts per hertz (V/HZ) ratio.

AC drives are an ideal choice for:

  • Damp, corrosive, or potentially explosive ambient motor environments
  • Applications requiring smaller and lighter motors
  • Controlling multiple motors with a single unit
  • Motors that don’t need regular maintenance (because of inaccessibility)

AC drives can provide tight speed regulation and high dynamic response in applications that include material handling, metering, web processes, and more. From the very small to extremely large, LEI represents, services and commissions AC drives for your application.

DC DRIVES

DC drives use converters to change AC current into DC current. Changes in speed can be made by either increasing or decreasing the voltage being fed from the drive to the motor.

DC drives are an ideal choice for:

  • Dry, mostly clean ambient motor environments
  • Applications that require a broader range of changing loads
  • Motors that need to reach speeds of 2,500 RPM starting torques that exceed 150%
