What is electric drive system?
Electric drive is an electromechanical system (mechatronic system) intended to set into motion technological equipment. It consists of an electric motor (motors), a transfer mechanism, an electrical energy converter, and a control system.
What are the methods of operation of electric drives?
We know that electrical drives mainly accomplishes three kinds of work, (1)Starting (2)Speed control (3)Braking It can be said that the electrical drives enable us to control the motor in every aspect.
What are the applications of electric drives?
Applications of Electrical Drives Electrical drives are extensively used in the huge number of domestic as well as industrial applications which includes motors, transportation systems, factories, textile mills, pumps, fans, robots, etc.
What are the advantages and disadvantages of electric drive systems?
Advantages of Electrical Drive 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.
What is the advantage of electric drive?
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.
What is the function of your drive control system?
A motor drive controls the speed, torque, direction, and resulting horsepower of a motor. Dc drives typically control a shunt-wound dc motor, which has separate armature and field circuits. Ac drives control ac-induction motors and, like their dc counterparts, control speed, torque, and horsepower.
What are the advantages of electric 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.
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 factors that influence the choice of electrical drives?
FACTORS INFLUENCING THE CHOICE OF ELECTRICAL DRIVES: 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 the typical elements of an electric drive?
Basic Elements of Electric Drive- Before discussion makes clear that an electric drive system basically consists of a mechanical load to which the required mechanical motion is imparted through a transmission drive usually equipped with gears or pulleys.
What is the main disadvantage of electric drive?
Disadvantages of Electrical Drives High initial cost due to the presence of power converters and controller electronics. Regular maintenance and high attention are required.
What is an electrical drive?
Definition: The system which is used for controlling the motion of an electrical machine, such type of system is called an electrical drive. In other words, the drive which uses the electric motor is called electrical drive.
What thermal management systems are required for electric drive vehicles?
Electric drive vehicles (EDVs) must incorporate thermal management systems for powertrain-related subsystems, including the power electronics, electric motors, and energy storage system (ESS) as well as the passenger compartment.
What is the source of energy in electrical drive?
The electrical drive uses any of the prime movers like diesel or a petrol engine, gas or steam turbines, steam engines, hydraulic motors and electrical motors as a primary source of energy. This prime mover supplies the mechanical energy to the drive for motion control.
What are the advantages and disadvantages of electric drive?
The electric drives have many advantages shown above. The only disadvantage of the drive is that sometimes the mechanical energy produced by the prime mover is first converted into electrical energy and then into a mechanical work by the help of the motor.
