What is your experience with ac/dc motors

DC motors are usually seen in applications where the motor speed needs to be externally controlled. AC motors work best in applications where power performance is sought for extended periods of time. All DC motors are single phase, but AC motors can be single phase or three phase.

AC and DC motors use the same principle of using an armature winding and magnetic field except with DC motors, the armature rotates while the magnetic field doesn’t rotate. In AC motors the armature does not rotate and the magnetic field continuously rotates.

In some applications today, DC electric motors are replaced by combining an AC electric motor with an electronic speed controller, known as variable frequency drives. DC electric motors are replaced with an AC electric motor and an electronic speed controller because it is a more economical and less expensive solution.

DC electric motors have many moving parts that are expensive to replace, and DC electric motor repair is usually more expensive than using a new AC electric motor with an electronic controller.

In our experience, combining an AC motor and drive proves to be the most cost effective solution for mostapplications. When servicing our customers in the field, we often recommend looking at the SMVector Series Variable Frequency Drive in combination with a three phase AC motor.

Why did Christianity take hold in some places more than in others?
zepelin [54]
- Christianity integrated most fully into regions where European colonial powers ruled, where there was an overwhelming European presence, where the established society had been defeated and disrupted, and where no literate world religion was already established.
- It had the least impact when it had to operate with the permission of non-Christian rulers, when it sought to convert in a society that was stable and well established, and when it sought to convert in a region where a literate world religion already existed.

If students gossip about teachers, is that also ethically wrong? why or why not ?
AlekseyPX

Shayshay12317,

It is indeed "wrong." Why? It is because if students gossip about the teachers, the teacher would be less likely to help that student pass their class. For example, imagine if Micheal was gossiping about how the teacher walks and the teacher found out Micheal said those things. So, when Micheal needs extra credit the teacher would be less likely to give him less credit because he said those things.

Hope this helps!
