using voltage controlled oscillator
motor can be control by using variable frequency drive
frequency is genrally cycle per second, and frequencies may be of a dc nature or ac , devices which convert dc frequency in to an ac frequency are frequency converters and devieces which convert ac frequency in to dc frequency are frequency inverters. because in terms of power electronics, devices which convert ac to dc are called converters, and devices which convert dc in to ac are called "inverters" 'mehboob hunzai" I'm a engineers in this devices, the frequency inverter is convert AC to AC but with variable frequency output, means the frequency & voltage are adjustable; The frequency converter can convert DC to AC, like 24VDC to 220VAC and also the frequency is adjustable. One most important thing is the out power of frequency inverter just can be used for controlling AC motor, while frequency converter can be treated as normal power supply as our daily using power grid.

Use a variable Frequency Drive. Sold by ABB, Allen-Bradley, and many others.
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.
Convert in coming signal to D.C. using a bridge rectifier. Use the voltage to run a voltage to frequency converter. You will have to scale the incoming signal to match the frequency range desired.
Using one of these converters will help to get the job you need down easier and faster then by doing it by hand it can easier to have one of these gadgets then not to have one
class midpoints can be computed
By changing the voltage through a potentiometer ( eg fan regulator )
You cannot obtain a three-phase supply from a single-phase system without using some sort of rotary converter.
Solve the problem using the + sign for the variable. Then solve the problem using the - sign for the variable. Report your answer as the answer that you got using + or the answer that you got using -.
Where can I find out about using a free PDF converter? Question Long-Form: I would like to know more about using a free PDF converter. Where can I find out more?
What kind of question is that. What resistors, what circuit are you talking about?
