AC & DC drives are common choices among companies seeking to improve efficiency and control of their applications
These drives are used to regulate the speed and torque of industrial machines; since these machines need to operate at varying speeds and forces depending on their specific duties, the inclusion of a drive is crucial.
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.
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, Renown 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 a cost-effective choice for medium to high horsepower applications. 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%
