Our Power Conversion engineering team has more than twenty years of experience with all types of motor drives. Depending on the power level required, these drive systems can be designed using large, integrated power modules, or can be based on discrete components. We supply virtually every component or sub-system needed for your drive circuit design.

We can assist your Motor Drive design team with:
  • Component Selection
    Our engineers can help you select the right components for you design, including capacitors, heat sinks, power semiconductors, ultracapacitors, resistors and integrated AC-DC and DC-DC converter modules. Interested in SiC components? Let us help you find the right part from our extensive selection of SiC discrete and module products.
  • Design Review
    Working together, we can review your design goals, provide specific design assistance, and even suggest design alternatives to help you meet those design goals easily and quickly.
  • Turnkey Design
       We also have the ability to provide complete design services for your specific motor drive circuit design project.

Please contact us here for design support regarding your specific Motor Drive application.

By offering deep technical expertise to support the latest products from the leading suppliers in Energy and Power Technologies, Richardson RFPD is uniquely positioned to help customers meet the challenges of changing markets.

In today’s heavily industrialized world, there are many industrial processes that depend on high-quality, powerful motor drives to supply power for any given industry’s precision motors and machines. These machines can be as large as the motors driving large thrill-rides at our local amusement park, or as small as the computer-driven lathe making mechanical parts for just about anything: clocks, engines, planes, heart-lung machines and dental equipment. In every case, the specialized power driving each of these machines needs to be dependable—and it needs to be the specific “type” of power that the individual load (the motor) requires to do its specific job.

For some precision motor drives, the designer must consider specifically how the load (the motor) starts-up, how it stops and changes speeds, how it operates during ‘steady-state,’ and even how it shuts-down safely—especially if power is lost unexpectedly. These industrial machines, then, are not simply plugged-into a convenience outlet for their power. These machines are provided various amounts of controlled power (DC or AC), depending on the individual requirements of the machine. This specialized power is derived from high-voltage three-phase electrical power, such as that provided by a utility company to a factory.

The block diagram shown on the Our Products and Services tab offers ideas and information to help you design a specialized Motor Drive circuit that meets your specific needs.
