Actuators Analysis NI ELVIS Mechatronics Device—The Quanser Mechatronics Actuators Board for NI ELVIS III is an add-on application board for the NI Educational Laboratory Virtual Instrumentation Suite III (NI ELVIS III). This device helps educators teach students principles of electromagnetic actuation, linear and PWM actuators, brushed and brushless DC motors, stepper motors, and servos. The Quanser Mechatronics Actuators Board for NI ELVIS III consists of a brushed DC motors, brushless DC motor, unipolar stepper motor, and servo motor. Onboard linear and PWM power amplifiers allow students to experiment with motor power systems. Feedback on the behavior of the motors is provided by onboard current sensing, and photomicrosensor for the brushed DC motor. The courseware covers three overarching topics: motor amplifiers, DC motors, and position-controlled actuators.
