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.
What are the advantages and disadvantages of an electrical drive?
Electrical drives have numerous application like pollution free, longer life, economical and easy transportation. Some disadvantages of electric drives are that in the failure of electricity, electrical drives cannot work and initial cost is high.
What are advantages of electrical drives?
Advantages of Electrical Drives
- Enough overload capacity without loss of life of machine.
- Four quadrant operation.
- Modifiable torque-speed characteristics.
- No requirement of warming up period.
- Higher efficiency.
- Easy control.
- Clean operation, no pollution.
- Wide range of speed control.
Which of the following is the disadvantages of group electric machine 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.
What is a electric drive?
An electrical drive is defined as a form of machine equipment designed to convert electrical energy into mechanical energy and provide electrical control of the processes. The system employed for motion control is called an electrical drive.
What are the advantages of electrical drive over mechanical drive?
electric drive is more clean as there are burning of any fuel and no fumes etc. mechanical drive requires burning of therefore it may contains ash or fumes etc. electric drive is flexible as it can be brought any where and can be control from any location. due to mechanical components this drive is not flexible.
What are the advantages of group drive?
Advantages : 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. Group drive has high overload capacity.
What are the advantages of individual drive?
Advantages of Individual Drive
- Since each machine is driven by a separate motor, it can be run and stopped as desired.
- Machines not required can be shut down and also replaced with a minimum of dislocation.
- There is flexibility in the installation of different machines.
What are the three types of electrical drives?
There are three general categories of electric drives: DC motor drives, eddy current drives and AC motor drives. Each of these general types can be further divided into numerous variations. Electric drives generally include both an electric motor and a speed control unit or system.
What are the different types of drive?
Types of Drives, Features and Principles (Motors And Drives)
- Mechanical. Mechanical variable-speed drives were probably the first type of drive to make their way into the industrial environment.
- Hydraulic Drives.
- Eddy-Current Drives.
- Rotating DC Drives.
- Electronic Drives (DC)
- Electronic Drives (AC)
What are the disadvantages of group drive?
Group drive has high overload capacity. Speed control of individual machine is very difficult. It does not give good appearances due to use of line shafting pulleys and belts. Group drives are less safe to operate.
What are the advantages and disadvantages of group drive shaft drive )?
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.
What is multi motor electric drive?
a group of electric motors that are interconnected by a common control system and drive the working members of a machine or installation (for example, rolling mills, paper machines, composite metalworking machines, and walking excavators).
What are the different factors affecting the choice of electrical drives?
Choice of Electrical Drives depends on a number of factors. Some of the important factors are: Steady state operation requirements: Nature of speed torque characteristics, speed regulation, speed range, efficiency, duty cycle, quadrants of operation, speed fluctuations if any, ratings.
What are drives used for?
A drive is a location (medium) that is capable of storing and reading information that is not easily removed, like a disk or disc. All drives store files and programs used by your computer. For example, when you write a letter in a word processor, the program is loaded from the hard drive.
What are the requirements of electric drive?
Components of Electric drives
- Power source.
- Motor.
- Power processing unit.
- Control unit.
- Mechanical load.
What is the advantage of AC drive compared to DC drive?
With DC drives, the motor turns at a speed directly proportional to the voltage applied to the armature. Advantages provided by AC drives include: Reduced power line disturbances, lower power demand on start, controlled acceleration, controlled starting current, adjustable operation speed, and adjustable torque.
What are the losses in electric drive systems?
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.
What type electric drive is used in cranes?
variable voltage variable frequency. 10? What type electric drive is used in cranes? Multimotor.
Why electric drive is becoming more and more popular?
Electric drive is becoming more and more popular because
(b) it provides easy and smooth control, flexibility in layout easy starting and facility for remote control.
Is a important feature of electric drives?
The main function of electric drive system is to transfer energy from storage system to wheels, which is used for overcoming rolling resistance, air resistance, acceleration resistance, and climbing resistance. When braking, the mechanical energy is converted to electrical energy back to the energy storage system.
