Dc Motors With Forward And Reverse Motion

[Girish]

Hi,

 

First of all i would like to let you know i am not a very techie guy.

 

I have a machine with 3 Phase, 230V AC, 1/8HP, 33 RPM, AC Induction Motor with Forward and Reverse Direction and speed control using VFD (Inverter) without need to change terminal connections for direction change.

 

I want to know if i can have a DC Motor which can also rotate in forward and reverse direction without changing the terminal connections and also i need to control the running of the motor from 0 rpm to 60 rpm.

 

Kindly advice what type of DC Motor (Preferably Brushless DC Motor) and Motor Speed Controller should i use.

Hello Girish

 

Welcome to the forum.

 

The device that you have will not be an inverter, but some form of DC rectifier and controller.

 

It is very common to use DC motors for speed control and for rotating in both directions. What you need is a four quadrant DC controller. This is a pretty standard piece of equipment available from a number of suppliers, although it is now more common to use an AC motor and inverter.

 

Best regards,

Hi Marke,

 

Thanks for your reply,

 

Just for your info, I am from India

 

I want to use a DC Motor because for varying the speed in a AC Motor we use VFD (Variable Freqency AC Drives) which is pretty expensive. in my case double the cost of my motor, and due to the very bad voltage conditions we have frequent problems with VFD requireing repairs or replacement necessary.

 

Hence i was told that if had a DC motor then it would be much better
