What is the reasons for the slight decrease in the speed of the motor from no-load to full load?
Without going into the math, the change in speed increases the torque the motor can supply. The further the motor speed and supply speed are apart (known as the slip), the greater the torque will be.
What is the main reason for the slight decrease of the motor speed when changing from no-load to full load?
It's because the same power now have to drive the weight of the armature plus the weight of the load hence the drop in speed. But this is usually short-lived as the armature will eventually draw extra current in order to drive the extra weight.
If you increase or decrease the frequency what effect on electrical machin?
If you're talking about an electric motor, increasing the frequency will increase the speed of rotation of the motor, and decreasing the frequency will decrease the speed of rotation of the motor. The other way of controlling a motor is to control the current; increasing the current increases speed, decreasing current decreases speed.
What are the various method of speed control of 3 phase induction motor?
you can control the speed of a motor by changing frequency, increase or decrease the field winding or by voltage regulation. in these method you can controle the speed of athree phese motor SANDEEP SARKAR
What happens to the rotor speed and rotor current when the mechanical load on an induction motor increase?
whenever the load increases,the current drawn by the motor to do or to fulfill the required energy to the load. so the current will increase generally.Increase in load will cause the full utilization of motor,so speed of rotor will decrease.
How will the speed and the slip of the motor change with increasing load in star wye and delta connection?
the speed decrease if increasing load..in star connection the speed lower
Why dc series motor cannot be start without any load?
If a DC series motor is started without load, the armature winding (winding that doesn't spin) current will be at a minimum, resulting in the motor going to maximum speed / runaway, which can cause things to fly apart. As Armature current increases, the speed of the motor will decrease. The armature current will be forced to increase / speed of the motor will be forced to decrease as more and more load is applied.
What happen to the rotor speed and rotor current when the mechanical load on an induction motor increases?
rotor speed will decrease....the rotor current wil increase.....
What happens to the rotor speed and rotor current when the mechanical load on an induction motor increases?
rotor speed will decrease....the rotor current wil increase.....
If the speed of the dc shunt motor falls due to loading what will be the effect?
on adding load on a dc shunt motor, the amount of current and torque will increase. but terminal voltage will decrease
How control dc motor using micro controller?
The speed of the motor depends on load, voltage and current. The speed can be maintain by using a method called Pulse code modulation (PWM). By changing (modulating) the width of the pulse applied to the DC motor we can increase or decrease the amount of power provided to the motor, there by increasing or decreasing the motor speed. mean we have to just change the duty cycle of modulating output.
What should you do when operation a boat in large waves and high wind?
head into the waves at a slight angle and reduce speed
