ABB's new motor is offered as a complete package together with a frequency converter and dedicated software. The package is offered in two configurations, one that maximises efficiency, the other maximising output.
The high efficiency package meets the latest most stringent efficiency level specified by the IEC; class IE4, super premium efficiency. For customers, this means 40 percent less energy losses than a conventional motor.
The motor and drive package is designed specifically for variable-speed drive operation, leading to further energy savings. Thanks to these savings the pay-back time of this package is very short, in many cases less than two years.
The second package, high output, is configured for maximum output. This motor-drive package offers a power density up to 40 percent higher than in a conventional induction motor. As a result the motor size can be up to two frame sizes smaller than a conventional induction motor, an important benefit for machine builders who often work with stringent space restrictions. Customers who buy this package get the high power density of an equivalent permanent magnet motor with the robustness of an asynchronous squirrel-cage motor.
Because the rotor runs cooler than other technologies, the bearings also run much cooler, making the motor much more reliable. With bearing failure accounting for around 70 percent of unplanned motor outages, customers will appreciate the longer greasing intervals and higher reliability offered by the new motor and drive packages.
