The combination of an electric motor, energy transmitting shaft and control devices for motion control is known as electric drive. The following figure shows the block diagram of a typical electric drive.

Based on their assembly, electric drives can be of the following three types −

  • Individual Drive

  • Group Drive

  • Multi-motor drive

In this article, let's check the advantages and disadvantages of using an Individual Electric Drive.

What is an Individual Electric Drive?

When an individual machine is fitted with its own electric motor, then the electric drive is known as individual electric drive. In case of individual electric drive, each operator has complete control on his machine.

The block diagram of the individual drive is shown in the following figure.

Advantages of Individual Drive

The most prominent advantages of using an individual electric drives are as follows −

  • It is possible to control the speed of individual machine easily.

  • These drives produce comparatively less noise.

  • Future expansion is possible.

  • Individual drives have good appearance and flexibility in the layout.

  • In case of individual drive, fault on any one machine does not create problem for other machines.

  • Individual drive is economical in long-term.

  • As in case of individual drive, each machine operates near to rated capacity, so the power factor and efficiency are better.

Disadvantages of Individual Drive

Following are the disadvantages of using individual electric drives −

  • The initial cost of individual drive is high.

  • There is power loss in transmission system equipment such as gears, pulleys, etc.

Applications of Individual Drive

Individual drives are used in −

  • Drill machines,

  • Lathe machines, etc.
