Variable Frequency Drives (VFD)
High performance, cost effective VFDs, ideal for both machines & process control. Unitronics VFDs offer options for both single and three phase VFDs from 0.4 kW and up to 500 kW.
Use as stand-alone inverters—or optimize your applications with a complete All-in-One package with our controllers and free, Ready-made Motion code.
New! B7 Series support Ethernet and precise, integrated closed-loop control for torque, speed, and position.
Q: Which motor types are supported?
A: The B1 VFD series supports Asynchronous Induction Motors
The B5 and B7 VFD series support Asynchronous Induction Motors and Permanent Magnet Synchronous motors

Unitronics VFDs can be used as a stand-alone product, or within an end-to-end solution: VFD, controller, and HMI.
This simplifies workflow by enabling you to:
- Obtain your VFDs, PLC + HMI controllers and related components, as well as technical support, from a single supplier.
- Operate your VFD directly from the controller’s HMI panel
- Use the same programming software as the PLC control and HMI application, to:
- Set-up and configure multiple VFDs in a snap
- Monitor and debug your VFD – either via UniLogic or Scope Trace
- Remotely Access your VFD via UniLogic software environment
- Effortless Communication- Simple communication based control . Ensuring your system provides robust operation & minimizing EMI effect.
- Cost Effective –
- Energy efficacy
- Reduce IO modules and cabling costs
- Short integration & development time
