Why is individual drive preferred over Group drive?
The advantages of group drive over individual drive area. Initial cost: Initial cost of group drive is less as compared to that of the individualdrive. b. Sequence of operation : Group drive system is useful because operations are stopped simultaneously.
What is meant by group drive and individual drive?
when one prime mover or motor is used for the number of machine tools on common shaft then the drive is called as group drive . it is also sometimes called as line shaft drive. Speed control of individual machine is very difficult. It does not give good appearances due to use of line shafting pulleys and belts.
What are the advantages of group drives?
Group Drive :
- Any Fault that occurs in the driving motor renders all the driving equipment idle.
- Efficiency low because of losses occurring in the energy transmitting mechanisms (Power loss)
- Not safe to operate.
- Noise level at the working spot is high.
- Flexibility.
Which of the following is the disadvantage of using a group drive?
Explanation: Group drive does not provide constant motor speed. It has less initial cost compared to individual drive setup. It also has low maintenance cost, but it has a great disadvantage that the speed of the motor is not constant. 2.
What is difference AC and DC drive?
The “AC” stands for alternating current. AC-type drives are also known as adjustable speed drives, adjustable frequency drives, and variable speed drives. In contrast, DC drives are used to convert alternating current into direct current (The “DC” in DC drives is an acronym for direct current).
What is a group drive?
A group drive is a place for groups, projects or collaborations of researchers to share files and data among themselves. Group drives can also be used as clearing houses for instrument or field data collection with integration into your scientific workflow.
How electric drives are classified?
Classification of Electrical Drives Electrical Drives are classified into two types based on running speed namely Constant speed drives & changeable speed drives. Electrical Drives are classified into two types based on a number of motors namely Single motor drives & multi-motor drives.
Which type of electric drive is used in crane?
Conventional AC operated crane drives use slip ring induction motor whose rotor windings are connected to power resistance in 4 to 5 steps by power contactors. Reversing is done by changing the phase sequence of the stator supply through line contactors.
Why is group drive better than individual drive?
Cost of group drive is less for given capacity of load. cost of one motors of given capacity is less than the cost of many motors of the same capacity. Total H.P of motor used in group drive may be less than the sum of the H.P of individual machines since all the machines may not be working at same time.
What’s the difference between a shared drive and a personal drive?
Unlike My Drive, Shared Drive belongs to an entire Team instead of one individual. Shared Drive spreads ownership and usage across a team or group instead of restricting to a single person, which can make collaboration easier. Shared Drive allows for more ownership, sharing and restore rights, with longer retention for deleted items.
What’s the difference between shared Google Drive and my Drive?
Both Shared Drive and My Drive allow businesses and individuals to have many benefits not afforded by keeping files on-premises or carrying data on removable storage. But what is the difference between using google team drives and sharing google drive files? What are the pros and cons of Google Drive, and what are Shared (Team) Drives?

What are the advantages of a group drive?
Sequence of operation: Group drive system is useful because all the operationsare stopped simultaneously.c. Space requirement: Less space is required in group drive as compared toindividual drive.d. Low maintenance cost: It requires little maintenance as compared to individualdrive.
What’s the difference between group Drive and shaft drive?
Group Drive : If several group of mechanisms or machines are organized on one shaft and driven or actuated by one motor, the system is called a group drive or shaft drive. Advantage : Most Economical. Disadvantage: 1. Any Fault that occurs in the driving motor renders all the driving equipment idle.
