Hi Sai Tez. Arduino can not drive a motor directly, same as Raspberry Pi. Saying that, you do not need an Arduino if you do not want it. You can control the Raspberry Pi GPIOs output, to logically control an interface, like the relay same as Arduino. For example, with the WiringPi library you can control the GPIOs for motor direction and delivery PWM for motor speed. The diagram that I sent before shows that. Of course, in that case the interface was obtained by a H-Bridge that can drive small motors. For big motors, relays, contactors, are needed.
Thanks

thank you +Marcelo Rovai , iam finding that which Relay is suitable for switching 3ph motors ,our test has been started . so firstly we connect relays at the "Direct online starters"
by using single phase supply and the relay is capable of 380v and 10A current rating one relay is parallel to start button and another relay in series with the stop button by using normally connection and normally open coils,

yes obviously we can use GPIO pins of Raspberry pi for controlling motor . I am totally agree with @Marcelo Rovai … we can control GPIO pins using wiring pi … I have some experience with Raspberry Pi . I am surely help you, if you will let me know the task @[Sai Tez] . you can mail me also some details on my mail -id - [email protected] . I will surely try my level best to solve your problems
