Unified motor and drive offers a single, compact and customisable plug-and-play solution
ABB’s new LV Titanium variable speed motor platform delivers the benefits of a high-efficiency motor and variable speed drive (VSD) technology in a single, compact, customisable, plug-and-play solution that enables industrial customers to minimise their energy consumption, save money and reduce carbon emissions.
The LV Titanium offers a simple and cost-effective way to provide IE5 Ultra-Premium efficiency for pumps, compressors and many other applications. As a drop-in replacement for existing direct-online (DOL) induction motors, the variable speed motor provides an easy upgrade path to a VSD-driven motor with a fast ROI.
The LV Titanium platform is more than a drive simply bolted onto a motor. Instead, it is engineered as a fully integrated concept, with an advanced drive module purpose-designed from the outset for optimal performance with a high-efficiency permanent magnet (PM) motor. This streamlined design, with the axial drive mounted on the end of the motor, saves space and makes the LV Titanium ideal for applications like vertical pumps. It is also particularly quiet in operation.
A further advantage of the LV Titanium is that it can operate over a wide range of speed and torque requirements, with the capability to deliver high torque at low speeds.
“We developed the LV Titanium in collaboration with customers who asked us to help them achieve energy savings and reduced carbon emissions without installation complexity,” said Stefan Floeck, Division President, IEC Low Voltage Motors at ABB. “This variable speed motor delivers just that – advanced performance in a compact, user-friendly and speed-controlled motor package that draws on our application expertise.”
Plug-and-play functionality means the LV Titanium needs no commissioning, as the fully integrated motor and drive are commissioned and optimised to work together before leaving the factory. This makes installation fast and easy, with no need for cabinets or electrical rooms, and specially trained personnel are not required.
The LV Titanium has an intuitive control panel with customer-friendly analogue and digital inputs and outputs (I/O) together with a simple built-in PLC, while its connectivity features include the Modbus RTU communications protocol for easy integration with PLCs and other control devices.
Thanks to its compact design and high power density, the variable speed motor is at least two frame sizes smaller than comparable induction motors, making it suitable for installations where space is at a premium, such as in replacing older, inefficient motors.
The possibilities for energy cost savings by switching to the LV Titanium are illustrated by comparing it with a conventional, standalone, fixed speed motor in a 7.5kW centrifugal pumping application – one of the main sweet spots for the IE5 variable speed motor. The annual savings on the electricity bill are estimated at well over €4,000 based on a typical energy cost for Europe of €0.21/kWh. At the same time, there is a yearly reduction of 6,000kg in CO2 emissions based on the average European carbon intensity factor of 0.3kg CO2/kWh. The LV Titanium variable speed motor is currently available in smaller sizes from 1.5kW, while the platform will expand to cover applications up to 30kW for a wide range of industrial sectors – from water treatment and chemical processing to food and beverage. In addition to being available off the shelf, the motor can be customised to suit specific customer requirements.
