QNET Mechatronic Actuators Board
This product is no longer available.
One of the topics covered in a typical introductory mechatronics course is understanding and application of actuators commonly used in modern mechatronic systems. The QNET Mechatronic Actuators board is an ideal tool to introduce hands-on a variety of actuators, and demonstrate their advantages, interfacing and operation, as well as design considerations and limitations. Designed exclusively for NI ELVIS platform and LabVIEW™ software, students learn principles of electromagnetic actuation, linear and PWM actuators, brushed and brushless DC motors, stepper motors and servos.

Product Details
The QNET Mechatronic Actuators board consists of a solenoid, two brushed DC motors, a brushless DC motor, an unipolar stepper motor, and a servo motor. One of the brushed DC motors is commanded through a linear power amplifier, the other is commanded by a PWM amplifier. The solenoid can be used to couple the two brushed DC motors. The brushless DC motor, stepper motor and servo motor are driven by a PWM amplifier. Current sense is used to read the current supplied to each of the motors, the angular position of the motors is measured by photomicrosensors.
