At what distance does a long straight wire carry a current?
Answer. Magnetic field, We have to find the distance from a long straight wire that is carrying a current of 12 A. Hence, at 0.08 m from a long straight wire carrying a current of 12 A.
What basic principle enables all electric generators?
The basic principle of all electric generators is electromagnetism. The magnetic field should be moved to generate electricity.
Which device is magnetic field present?
Generator, DC and AC motor, because it composed magnets that has magnetic field that will move the electrons inside of the copper wires.
How is an electric motor different from a generator?
Converting energy from one form to another is the key to understanding the differences between electric motors and generators. An electric motor converts electricity into mechanical energy, providing a power source for machinery. A generator does the opposite of this, converting mechanical energy into electricity.
How are Motors useful in our daily life?
Electric motors are extremely important in modern-day life. They are used in vacuum cleaners, dishwashers, computer printers, fax machines, video cassette recorders, machine tools, printing presses, automobiles, subway systems, sewage treatment plants, and water pumping stations, to mention only a few applications.
Are motor controllers important in industry?
It’s essential to ensure that motors and motor starters are adequately protected. The control manufacturers are mainly involved in the development of improved and cost-effective motor protection devices. Moreover, to ensure motor protection, overload relays are used in circuits to protect motors and motor conductors.
What are the four major factors when installing a motor control system?
Explanation:
- power source that is need for operate machine.
- motor type that is depend on our work output.
- motor connection need horse power and service factor etc.
- environment that is also important for outside of equipment with dust and moisture etc.
- controller type it is depend upon type of motor and its purpose.
What is the most important function of motor control system?
Motor and Circuit Protection One of the major functions of most control systems is to provide protection for both the circuit components and the motor. Fuses and circuit breakers are generally employed for circuit protection, and over load relays are used to protect the motor.
What is the importance of control system?
Control is one of the managerial functions like planning, organizing, staffing and directing. It is an important function because it helps to check the errors and to take the corrective action so that deviation from standards are minimized and stated goals of the organization are achieved in desired manner.
What is the principle of control system?
A control system is a system of integrated elements whose function is to maintain a process variable at a desired value or within a desired range of values. The control system monitors a process variable or variables, then causes some action to occur to maintain the desired system parameter.
What are the basic functions of motion control?
Motion control board mounts functions to output pulse train at designated pulse number or frequency. It can automatically output control pulse according to motion parameters such as target position, velocity, acceleration and deceleration rate, etc. It has various limit input functions for positioning control.
What way can we control motion?
Answer Expert Verified Motion exist because there is an unbalance force acting on an object. By applying exact amount of force and the direction of the force you are exerting, it can can control motion. The way we move our body, hands, head, feet, all of these are controlled motion.
How do we control motion?
The motion controller is the brain of the system, controlling the motion path, the servo loop closure, and the sequence execution. The controller sends a low-power command signal to the motor drive or the amplifier in the digital or the analog form.
What is meant by motion control?
Motion control is the engineering discipline focused on moving a load from one place to another. It does this by precisely controlling the position, velocity, and acceleration of the load under defined operating conditions.
How can we control motion and use it to your advantage?
Yes we can control motion by the use of different forces. Force can make the object move and it can make the object stops. It can also change the direction of motion. We are able to build different mode of transportation by the advantage of understanding motion.
What drives the motion of motor?
The controllers are telling the drives where to move the motors that turn the electrical energy they receive into mechanical energy. The motors produce the torque to create the rotational force or linear force when connected to an actuator to rotate at a setpoint speed or move to a commanded position.
What are the motion control systems used in CNC?
The Three Most Basic Motion Types
- Rapid Motion (Also Called Positioning)
- Straight Line Motion.
- Circular Motion.
Which motor is used for precise control?
1 Electrodynamic Rotary Motors for Precision Positioning Electric motors have also become a mainstay of the precision automation and positioning industry. They are usually smaller than industrial motors and have to meet different requirements. Today, there are many variations of the original DC motor.
