Question

Merits and demerits of electric drive ?​

Answer 1

Answer:

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.

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.

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 :–
