Motor Speed Control:
- Simple PWM code is suitable to vary the speed of the motor.
- Figure shows the PWM is interfaced through the DC motor through the motor drive.
- By varying the voltage applied to the DC motor by PWM will change speed.
- Figure shows the Motor speed control with direction change.
- Typical connection from the FPGA development board.
- Direction and enable(PWM) are the signals driven from the FPGA I/O.
- It is interfaced to the motor through H-Bridge circuit. VM. Voltage applied to the motor that is controlled through EN (PWM signal)
- L293 D is the driver circuit cable to drive two 5/12V DC motor.
- This principle is applicable for the high voltage DC motor with suitable drive circuit
- Using Class 12 PWM code the open loop speed control can be implemented.
