How is the speed of a motor controlled? Answer needed within 24 hours.?

Answer 1

by the voltage supplied to it!! i think

Answer 2

It depends on the type of motor, and its use.

Example: DC motors require a series connexion to the armature or armature shunt winding to increase speed. A Rheostat or Potentiometer connected in series the shunt winding or series winding will control the speed. A key switch, 3 point switch, or sinestron switch, with different resistive loads at each terminal will also accomplish this.

A motor's speed may also be by solid state relays, PLC's, MotorControllers, and related programs.

Answer 3

If you are talking about an electric motor, the speed depends on voltage... the higher the volts, the higher the speed. To run it at variable speeds, the motor controller will feed timed pulses of current into the motor, the higher the frequency of the pulses, the higher the speed.

Answer 4

electric motors are controled by increasing/decreasing the voltage through it (a bit like water through a pipe pouring over a water wheel the more you pour over it the faster it goes) or if it is a 'stepper motor' it feeds back the time it takes to complete one revolution to a computer which increases or decreases the voltage to ensure a set speed.

Answer 5

what kind of a motor are u using?
There are many ways to icrease the speed of motor based on its type and field of application.

Basically increasing the current through its coils increases its speed.

if u are using electromagnetic motor, u can increase the magnetic field (again by increasing voltage applied)

u can decrease the load applied if it is not a constant speed motor.

Answer 6

the speed is controlled by the motor controller thingy ma-bob

hope that helped

Answer 8

electric, steam or gas

All of them it is the ammount of enengy that you put in...
