Based on the analytical and simulation results, a prototype LABLT motor is fabricated using aerospace grade materials. A static test is conducted and a peak torque of 2.5 Nm is achieved for an armature current of 2 A with constant torque region of ±20° mechanical. Various position commands are issued at three rate inputs namely 1 deg/s, 2 deg/s, and 3 deg/s between ±20° and the results show a position accuracy of less than 0.32°. From the experimental investigations, the motor is found suitable for driving the scan mirror at three different rates and any six different positions within the constant torque region of ±20 deg mechanical. The motor is able to control and precisely position the scan mirror in the satellite mechanism. The requirement of the scan mechanism, to drive the scan mirror with a nominal torque of 2 Nm for ±20 deg mechanical at three different scan rates and six selectable scan positions is achieved.
