General Magnetic of Calgary, Alberta, Canada has developed a large 85-horsepower MagnoDrive Permanent Magnet PCP Top Drive Motor that drives progressive cavity pumps (PCP). In the development stages of their MagnoDrive, General Magnetic noticed a problem when conducting field tests with an initial variable speed drive (VSD) it had selected. This is when they contacted ABB whose people visited GM, did some research, and in early 2014 offered to provide an ACS880 for testing.
