However, the technology has not been widely implemented on larger sized motors due to the relatively high cost of producing the permanent magnets. Over the past 4 years however this cost has been reduced and the benefits of PM motor technology is now economically feasible for larger drilling equipment such as utility winches, drawworks and top drives. Another important reason why the PM motor technology now is feasible in larger machines is the recent development of improved control systems for these motors.When using PM-motors in winch applications, operational safety is improved due to the inherent failsafe electrical braking characteristics in PM-motor technology. Another benefit is that the power-to-weight/size ratio can be improved up to 30% compared with a standard induction motor. Permanent magnet motors additionally lend themselves to greater flexibility for high torque and low speed applications thus reducing the need for gear transmissions and in some cases eliminating the transmission all together. This simplifies the overall mechanical design and improves the ability to accurately control the machines.This paper focuses on the opportunities to introduce larger drilling equipment with better performance characteristics related to increased capacities, improved control, enhanced safety, and reduced maintenance as a result of simplified mechanical design. The paper also discusses the challenges related to current regulations and standards that do not recognize with new and improved technology. Manufactures of drilling equipment should work closer together with the authorities and certification organizations to update standards and regulations so that this does not hinder introduction of new and better technology.Abbreviations PM Permanent Magnet DC Direct Current AC Alternating Current VSFD Variable Speed Frequency Drive PLC Programmable Logical Controller UPS Uninterrupted Power Supply DnV Det Norske Vertias MRU Motion Reference Unit EN European Norm NOV National Oilwell Varco PM Permanent Magnet DC Direct Current AC Alternating Current VSFD Variable Speed Frequency Drive PLC Programmable Logical Controller UPS Uninterrupted Power Supply DnV Det Norske Vertias MRU Motion Reference Unit EN European Norm NOV National Oilwell Varco View LargeDefinitions(as used in this paper)AC-motor = Induction, squirrel cage motor controlled via a variable speed frequency drivePM-motor = Permanent magnet motor controlled via a variable speed frequency driveIntroductionNew products utilizing permanent magnet motor technology have recently been introduced to the drilling industry in different applications.
