Which of the following is a characteristic of a group drive system?

Electrical Drives

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

Group Drive:

• A group drive system uses a high-powered motor to drive a common shaft. When several machines are organized on a single shaft and are driven by a single large motor, this system is known as a group drive.
• A key characteristic of a group drive system is its lower capital cost compared to other drives. This is because a single, larger motor and associated control gear can power multiple machines connected to a common shaft, rather than requiring a separate motor for each machine. 
• Examples: Food grinding mills, paper mills, etc.
   

Multi-motor Drive:

• A multi-motor drive system uses multiple electric motors to power different parts of a machine, each motor operating its own mechanism.
• This allows for independent control and operation of various machine functions, as seen in traveling cranes where separate motors handle hoisting, long travel, and cross-travel. Example: Cranes
   

Individual Drive:

• In an electric drive system, if an individual machine is fitted with its motor and each operator has complete control over their machine, then it is termed as an individual electric drive.
• Examples: Drill machine, lath machine, etc.
