Will the motor start OK if the supply is current limited to, say, 2A?

 

This is a separate question from the discussion in the original thread - http://forum.allaboutcircuits.com/showthread.php?t=23399

We prefer you to always start a new thread for each new question.

If the motor is not under load, it will start with limited current.

 

My question was aimed at establishing whether the motor in the original thread could be powered from a current limited supply, thereby eliminating the need for a supply that can handle inrush currents of 11A.

Current limiting is a piece of cake. Why isn't this an appropriate approach for the problem in the original thread?

 

Pardon me if I got the wrong impression from your post. The discussion had settled on a PS that would supply the startup current.

You are correct the current limiting is quite simple. The question not asked or answered is about loading on the motor after startup. Any load would be problematic with a current limited supply.

Which motor?


It may start or not depending on the load on its axis. If you limit the stall current you reduce the starting torque.
