What force is applied in working of a fan?
In a fan, the force that is applied is typically generated by an electric motor that drives the rotation of the fan blades. This motor creates a torque that spins the blades and moves air through the fan. The movement of air is then produced by the fan blades as they push or pull the air in the desired direction.
A motor has an efficiency of 0.4 how much useful energy is produced from 250 J?
The useful energy produced by the motor can be found by multiplying the input energy by the efficiency. Therefore, 250 J * 0.4 = 100 J of useful energy produced by the motor.
What is the difference between speed and torque control?
Speed control is used to regulate the speed of a motor by adjusting the voltage or current supplied to it. Torque control, on the other hand, focuses on regulating the amount of force or rotational power produced by the motor. Speed control is more about maintaining a desired speed, while torque control is about adjusting the motor's output force.
What instrument do you use to measure kinetic energy with?
A dynamometer is a common instrument used to measure kinetic energy. It is designed to quantify the force or torque produced by an engine, motor, or other mechanical system.
How is torque produced in a dc motor?
Torque in a DC motor is produced by the interaction between the magnetic fields created by the stator (fixed part) and the rotor (rotating part). As electric current flows through the coils in the stator, it creates a magnetic field that interacts with the permanent magnets or electromagnets in the rotor, causing it to rotate and produce mechanical torque.
Why is DC series motor is used more than shunt wound DC motor?
Series DC motor develops a very large amount of turning force called torque from standstill and can be operated by using either an AC or DC power source.
How can magnetic energy be converted to mechanical energy?
Magnetic energy can be converted to mechanical energy through the use of a system called a magnetic motor. In a magnetic motor, the interaction between magnetic fields generates a force that causes movement. This movement can be harnessed to perform mechanical work, such as turning a shaft or driving a load.
What is a ka?
There is a model of car produced by the Ford Motor Company which is called a Ka.
What is the purpose of the fields of a dc shunt motor?
DC Shunt motor: dc shunt motor is a motor with dc supply given to the inductor connected in parallel with the armature of a motor. The inductor connected in parallel with the armature of a motor called field winding of a motor.In dc shunt motor: When current flows through a conductor ( here it is armature in case of dc shunt motor ), magnetic field is produced which is circular and when this conductor is placed perpendicular in the magnetic field ( which is produced by the current or say dc supply that given to the inductor or say field winding of the dc shunt motor ), the main magnetic lines get bent due to the interaction of the two fields. These lines of force experience tension and try to become straight. So, a force is produced on the conductor ( armature ), due to which the conductor ( armature ) will rotates. The direction of force can be found by Fleming's right hand rule.Main Answer: Thus, it should be understood that field winding in dc shunt motor stands to get interaction of the two field in such a way that force is produced on the armature so that the armature get to rotate.Some Facts: Actually the current in armature is due to the mutual induction by field winding to the armature. That means only field winding get dc supply through which current and so magnetic field is produced in armature that try to oppose due which it is produced, that means it oppose the main magnetic field of field winding.
What was the first car called a motor wagon?
The very first practical automobile ever produced was called the Benz Patent Motorwagen. Produced in 1885 in Germany by Karl Benz.
What is starting torque?
The torque which is produced during the starting of motor is simply called as starting torque.
Which is used to convert DC to ac?
A power switching circuit called an inverter. You could also use an electromechanical motor-generator: DC motor turning an alternator.
What is Back emf of DC motor?
In dc motor, the armature conductors are revolving in the magnetic field and emf is induced in the armature conductors. The direction of the induced emf is in opposite direction to the applied voltage as per Flemings left hand rule. So, the induced emf in motor is called as back emf or counter emf. Vydehi
How much does an electrical motor 380V of 150 HP losses after turning on?
how much does an electrical motor of 380V AND 150HP losses of his effeciency after turning on
What kind of motor is used in an eram electric supercharger?
The motor used in the eram is a massed produced called the Johnson Motor. You can order them by the hundreds. Because of the motor that is used with the eram you will most likely only get 3 to 5 horsepower.
Is there a air filter on a force outboard motor?
Is there a air filter for a force out board motor
Why is the blower motor not turning on?
The blower motor may not be turning on due to a faulty motor, a blown fuse, a malfunctioning relay, or a problem with the thermostat. It is recommended to check these components to determine the cause of the issue.
