hi,
in my project a want to design drive & control speed circuit for dc-motor
(1.5 hp,24 v)
PWM is the tech. that i will use to control the motor speed because i need smooth variation in speed, the PWM signal is taken from PIC.
in that circuit i want to use the darlington transistor (TIP 122)(up to 5 A)
dc-motor current may rise to 20 A, so i want to ask if i can use the TIP 122
in the way which obtaind in the graph.
and thnks....
