mine has the same problem...........
We could use some help here............... sounds weird to me.
depends on if you have a 3 speed motor , if not its fixed on speed,
DC motors use PWM (pulse width modulation), which can easily increase or decrease the power to the motor, thereby increasing or decreasing the motor speed by modulating the width of the pulse. Stepper motors have fixed frequencies, thereby having fixed motor speeds. As a result, the speed of the stepper motor cannot be controlled when the load is increased.
You will need to be more specific with your question. What exactly needs to be fixed? The numbers won't roll or the speed is not displaying? You will need to be more specific with your question. What exactly needs to be fixed? The numbers won't roll or the speed is not displaying?
There are many application of motor speed control. Mixer in a food process application needs to run at different speeds. Machine needs to run at different speeds according to required production speed. There are plenty of such application for energy saving etc.
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.
Average speed (83 mph) is a measure of the change in location relative to some fixed point (or displacement) divided by the amount of time taken for that change.The change in location and the passage of time are independent of the location of the observer and hence the result.Average speed (83 mph) is a measure of the change in location relative to some fixed point (or displacement) divided by the amount of time taken for that change.The change in location and the passage of time are independent of the location of the observer and hence the result.Average speed (83 mph) is a measure of the change in location relative to some fixed point (or displacement) divided by the amount of time taken for that change.The change in location and the passage of time are independent of the location of the observer and hence the result.Average speed (83 mph) is a measure of the change in location relative to some fixed point (or displacement) divided by the amount of time taken for that change.The change in location and the passage of time are independent of the location of the observer and hence the result.
A normal motor run at a fixed speed depending on: AC motors: Voltage and frequency (Hetz) and number of poles DC Motors: Armature voltage Stepper motors speed depend on the drive pulse frequency.
If you have only high speed on the blower motor or you are missing one or more low speeds, chances are the blower motor speed resistor is burned out.
You'll find the heater blower motor resistor in the heater/air conditioner compartment. This compartment is location underneath the dashboard. This is the part that allows the heater blower motor to change the fan's speed.
It is a variable frequency drive, used to control the speed of a 3-phase motor all the way from stopped to full speed, and anywhere in between. Also called VSD, for variable speed drive, they are used to control pumps, fans, conveyor belt drives, anywhere a motor needs to be controlled to a precise speed other than the normal nameplate full speed, or where the speed needs to change to meet different operating conditions.
high speed internet that uses an antenna on a house or business to communicate with a tower location via radio signals.
Could be motor mounts, the tires out of alignment or out of balance, or the steering needs work.
