►Product structures
►Why do you need a VFD:
Variable frequency drives (VFDs) control the speed of AC induction motors and often save energy, especially while running applications like pumps and fans. When sized correctly, VFDs can also be used for phase conversion if you need to run a three-phase motor but are limited to a single-phase supply.
VFDs modify the electricity from the utility to run the motor precisely and provide the right speed and torque to optimally run the application. Drives dictate motor speed and torque by controlling the ratio of frequency and voltage — commonly referred to as the volts/hertz curve.
Motors without VFDs often wear out sooner and consume significantly more energy than may be needed for the application. This is especially important for applications with fluctuating load or speed requirements.
For example, to maintain a set PSI or flow rate on a pumping system, a VFD can be used to automatically accelerate or decelerate the pump to meet the immediate demands of the system. Or on Hammer Mills and large cone crushers, like those found in a Metso HP4, the VFD can be used to increase torque when a load surge requires more output from the motor for a short amount of time.
1. Wireless diagnostics
Wireless diagnostics represent the future of VFDs whether it’s Wi-Fi, Bluetooth, or something else entirely. In a typical plant where access to a drive in a closed enclosure may be limited, engineers can connect directly to the system from a distance using the wireless signal built into the drive.
Online software enables engineers to view and diagnose problems without touching the drive or its enclosure.
2. Flexible integration
VFDs with flexible integration allow engineers to solve for the application challenge once and then interface to an upper-level programmable logic controller (PLC) of choice.
For example, say an OEM is selling a given machine to customers both domestically and abroad. Regional trends in PLC preference are not an obstacle for machine integration. The OEM can take a drive with multiple
communication options, solve the machine application once, and pick the option that matches the upper-level controller choice for each customer.
VFDs constructed specifically for flexible integration usually consist of a single basic inverter with control or networking modules that can be selected at will.
3. Modular memory
Gone are the days when technicians would have to go into the keypad to program a replacement VFD. Soon, having to use a PC or even just a USB stick to transfer the configuration to a replacement drive will be a thing of the past.
Today, drives with removable, modular, nonvolatile memory make maintenance quick and easy. They eliminate the need to connect additional hardware. If a piece goes bad, device replacement is as simple as taking the memory module out of the old drive and putting it into a new one.
4. Predictive maintenance
Manufacturers are gathering massive amounts of data from their machinery and manipulating it into business intelligence that drives predictive maintenance.
The Internet of Things (IoT), a global trend in every industry, has had an impact on VFDs by speeding and simplifying the flow of information from machine to technician and back again. As such, manufacturers are making changes to everything from their machines to their information technology (IT) departments to facilitate the collection, analysis, and application of drive data.
From a hardware perspective, teams are moving away from serial and toward Ethernet as the network of choice. Basic IT departments are familiar with Ethernet switches, hubs, and routers, resulting in a more seamless integration when it comes to data transfer.
Complex communication strategies are requiring modern VFDs to report lifetime counters, production rates, downtimes, power output, and more for better real-time decision making.
