Date: April 24, 2008 To: Chris Vincent From: Matthew Swaters Subject: Dynamic characteristics of DC permanent magnet motor Objective Permanent magnet direct current (DC) motors use permanent magnet to generate the magnetic field for a much simpler motor structure. The output from the motor is the torque generated from the rotating shaft and is proportional to the armature current, which is determined by the applied DC voltage, circuit impedances, and induced voltages. The object of the experiment is to calibrate the torque sensor from which the relationship between the motor torque and speed is determined. By using a dynamometer to vary the motor torque output, applied through an MR brake the speed is detected using a shutter wheel and light device, and as a check a hand held revolution detector was also used. From the data, torque-speed curves were formed to visualize the effects and to be used for future reference. Instrumental Setup/Calibration
