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.
