datum electronics CASE STUDY SPERRE AS: MEASURING TORQUE TO IMPROVE MOTOR PERFORMANCE & EFFICIENCY ALGORITHMS

SPERRE AS: MEASURING TORQUE TO IMPROVE MOTOR PERFORMANCE & EFFICIENCY ALGORITHMS BACKGROUND STORY ROVs were developed in 1960s and used by US Navy to perform deep-sea rescue operations and recover objects, such as lost bombs, from the ocean. Despite the fact that they have been with us for less than half a decade, technological development of ROV vehicles have come a long way. Not only have ROVs matured considerably technologically, but they've become an essential tool in a whole array of industries, serving oil & gas, underwater construction, military, scientific and even filmmaking needs.

SPERREAS: MEASURING TORQUE TO IMPROVE MOTOR PERFORMANCE & EFFICIENCY ALGORITHMS Sperre As is a company in Norway that specializes in providing customised ROV solutions for inshore and offshore use. Their different models of ROVs and TMSs (Tether Management Systems) are used in initial subsea construction, as well as subsequent repair and maintenance of subsea structures, pipelines, etc. Their products are also utilised in a number of military applications, particularly in minehunting and minebreaking. Apart from that, ROVs are working for archaeological and scientific purposes and...

SPERRE AS: MEASURING TORQUE TO IMPROVE MOTOR PERFORMANCE & EFFICIENCY ALGORITHMS THE CHALLENGE “The challenge was to demonstrate that the motor could meet the worst case drive requirements at temperatures over 50°C. With the Datum M425 Torque Sensor we were able to accurately measure the motor heat generation , do this quickly and be confident in the test data”. With the rising cost of energy, use of VSD with the ability to control the motor’s speed and torque is growing at an increasing rate. Looking to continuously improve product performance and efficiency for their clients, for the last...

SPERRE AS: MEASURING TORQUE TO IMPROVE MOTOR PERFORMANCE & EFFICIENCY ALGORITHMS DATUM SHAFT POWER MEASUREMENT SOLUTION After a full check up and assistance from Datum’s support team, the torque transducer was installed on a test rig for repetitive engine testing. This continuous testing was done to optimize and verify the closed loop sensorless control by maximizing the amount of torque per ampere current drawn from the VSD. As a result, the Sperre As team was able to tune the open loop U/F curves to work optimally for a given load (torque) for optimizing U/F controls in old drives,...

SPERREAS: MEASURING TORQUE TO IMPROVE MOTOR PERFORMANCE & EFFICIENCY ALGORITHMS THE IMPACT “ The overall design and all-digital interface of the Datum sensor are great. It avoids introducing errors or noise in analog signals.” Even though tests are still in a very early stage, the company was able to significantly improve motor control tuning. Their current progress shows there is a lot of potential for the new VSD system to enter market as an innovative product, allowing their clients to maximise their competitive advantage. Even now, as motor output can now be proved and...
