Variable Frequency Drives (VFD)
One of the main advantages of using a VFD is the energy cost savings associated with speed control. When using belts/sheaves or gearboxes to reduce speed, the motor still runs at full speed; however, a VFD reduces the actual motor speed, which reduces the amps drawn by the motor. This reduces the amount of energy used—and saves you energy costs. By ramping up the motor speed slowly, VFDs also help customers save energy by reducing the in-rush and mechanical issues associated with starting motors across the line.
Three main reasons to consider using a VFD:
- Possible financial rebate incentives from your energy provider.
- Improved efficiency of motor-driven equipment by matching speed to changing load requirements, allowing accurate and continuous process control over a wide range of speeds.
- Yaskawa VFDs provide the benefits of network communications, a user-friendly interface, easy auto-tuning/programming, and ease of installation. Because all Yaskawa VFDs are rigorously tested, you can be assured of built-in quality and reliability.
- A VFD may be used for control of process temperature, pressure, or flow without the use of a separate controller. Suitable sensors and electronics are used to interface the driven equipment with the VFD.
- Lower maintenance costs, as lower operating speeds result in longer life for bearings and motors.
- The motor does not require a starter.
- The ability of a VFD to limit torque to a user-selected level protects driven equipment that cannot tolerate excessive torque.
- Users can utilize multi-motor applications, such as pumps or fans, with one control unit.
- High-speed applications for the wood finishing industry.
