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.
I think the answer is All of the above
The correct answer is A) prevent monopolies.
Financial regulatory agencies focus on preventing monopolies because monopolies can be negative in a capitalist economy.
A monopoly is when one company has almost complete control over one specific market. For example, John D. Rockefeller was considered a monopoly by many people as his company Standard Oil controlled roughly 90% of all oil created in the US during the late 19th century. This type of control by one company can have a negative effect on the consumers. This is due to the fact that the monopoly has very little competition. Since there are few (if any) companies that can compete with the monopoly, the company that has cornered the market may have the chance to raise prices as high as they want. This is due to the fact that there is no other source to get this good from. This is why the government regulates the development of monopolies.
