Part 1: Multiple Choice - only one answer is correct!
Part 2: project task
An encoder is flanged to the 24V DC motor and outputs a square wave signal of 4 times the frequency per revolution. How this system works, you can see in the small video clip:
The circuit diagram is shown below:
1. For which maximum voltage (peak value!) must the diode V1 be designed if the transformer has an output voltage of 24 V?
The rotational speed is detected by a encoder, which supplies rectangular pulses to the control. The encoder signals at minimum speed and maximum speed are shown below:
2. What is the frequency of the encoder signal at low and high speeds.
3. How long does the motor need for a complete revolution at low and high speed?
