How do you change the speed of motor without change pole and frequency?
On an AC motor you basically vary the frequency on a DC you can vary the voltage.
What are the types of motor controls?
motor can be control by using variable frequency drive
How do you change AC motor speed?
A change in frequency of the motor will cause a change in the speed of the AC conveyor motor. This frequency change is brought about by a device called a Variable Frequency Drive. It is used to vary the frequency of the motor from 0 to 100%. I have no idea what the second answer is talking about. ANSWER: considering that no mention of type of motor is involved the frequency change theory is quite invalid since 50 or 60 Hz AC line runs clocks from banks to wake up calls and while it is true that the frequency is not accurate from second to second it is however very accurate from minutes to minutes.
Can the rpm on a sears 1 hp electric motor be changed?
yes, you can. in A/C motor rps(rev/sec) is N(rps)= f/p where f is the frequency and p is the number of pair poles. By increasing or decreasing the frequency the rps will change accordingly. By having less or more pair poles the rps will be increased or reduced. the more pair poles the lower will be the rps.
How does a frequency inverter work?
A frequency converter converts alternating current of one frequency to alternating current of another frequency. Generally it's used for controlling the ac motor speed by changing the supply frequency.
What is meant by VFD?
A variable-frequency drive (VFD) is a system for controlling the speed of a rotational or linear alternating current (AC) electric motor by controlling the frequency of the electrical power supplied to the motor.[1][2][3] A variable frequency drive is a specific type of adjustable-speed drive. Variable-frequency drives are also known as adjustable-frequency drives (AFD), variable-speed drives (VSD), AC drives, microdrives or inverter drives.
What is meant by a sounds frequency?

How do you change the speed of motor without change pole and frequency?
On an AC motor you basically vary the frequency on a DC you can vary the voltage.
How do you decide whether the variable frequency drive is compatible with my DC motor or not?
Variable frequency Drive is not compatible with a DC Motor. VFD can be used only with AC motors, where frequency plays a key role in defining the speed of the motor.
How does an ac drive variable speed drive operate to control speed?
Answer #1 It varies the frequency fed to a synchronous AC motor. As the frequency changes, so does the motor speed. Answer #2 The formula for calculating speed is: (120 X motor supply frequency) / number of poles 120 is a fixed number, so is the number of poles for a given motor, hence the only variable is the motor supply frequency. AC drives vary the motor supply frequency in turn achieving speed control.
Speed of DC Motor can be controlled by a frequency variable?
by using a frequency tuner in input we can change input frequency and in this way speed of dc motor will also vary. <<>> Varying the frequency (VFD) only works on AC motors.
How does a frequency drive work?
Frequency drives are an adjustable-speed drive used for electro-mechanical drive systems. They control the motor speed and torque by varying motor input frequency and voltage.
What is meant by zero phase frequency?
The zero phase frequency is the frequency at which the phase of the input signal and the output signal match.
What are the types of motor controls?
motor can be control by using variable frequency drive
Electronic component used to control speed of a motor?
In industrial, there is a device called variable frequency drive (allso frequency inverter, ac drive) to control the motor speed by adjusting output frequency.
What determines the speed of an AC motor?
The higher the frequency the higher the RPM the motor will turn
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.
