Question

Merits and demerits of electric drive ?​

Answer 1

Explanation:

Disadvantages of Electrical Drive

The application of the drive is limited because it cannot use in a place where the power supply is not available.

It can cause noise pollution.

The initial cost of the system is high.

It has a poor dynamic response.

The output power obtained from the drive is low.

Answer 2

Definition of Electric drive :–

✒️ The system which is used for controlling the motion of an electrical machine, such type of system is called an electrical drive.

Merits of Electric drive :–

✒️ The following are the advantages of electrical drive.

• The electric drive has very large range of torque, speed and power.

• Their working is independent of the environmental condition.

• The electric drives are free from pollution.

• The electric drives operate on all the quadrants of speed torque plane.

• The drive can easily be started and it does not require any refuelling.

• The efficiency of the drives is high because fewer losses occur on it.

Demerits of Electric drive :–

✒️ The power failure completely disabled the whole of the system.

• The application of the drive is limited because it cannot use in a place where the power supply is not available.

• It can cause noise pollution.

• The initial cost of the system is high.

• It has a poor dynamic response.

• The output power obtained from the drive is low.

• During the breakdown of conductors or short circuit, the system may get damaged due to which several problems occur.
