How does a heater use a motor?
Motors in heaters are to run the fans to distribute the heat over a larger area.
What is the difference between axial in-line fans and centrifugal inline fans?
Axial fans are like a propeller - like most domestic fans. Centrifugal fans are like water or paddle wheeels that sit inside a case. Instead of water turning them, the wheel is driven by the motor and that moves the gas. In-line merely means that the fan sits in the gas flow.
What is the principle operation wound rotor induction motor?
Considering a split phase single phase motor: The basic motor has a run winding uses 2 poles (or some equivalent), so the motor is activated by the single phase at 180 degree times. This needs a spin to get it started. The direction is according to the direction of the starting spin. It is an induction motor, meaning the rotor has shorting bars. The stator field is connectd to the supply, and induces the required magnetic field in the rotor by transformer action, as for other induction motors. The starting circuit has the purpose of getting the motor to spin up to sufficient speed for the run winding to take over. The rotation needs some sort of flywheel (inertial) action to carry it through the periods of zero magnetic reaction. It might use a rotor with a commutator for starting, with a centrifugal device that shorts the rotor once the speed is sufficient, so it converts to an induction motor. This method is not used much nowadays. It can have high starting torque for use with compressors for example. A common approach is to have a second field winding for starting, with poles at 90 degrees to the run winding, so there are four (or equivalent) poles. This is a two phase motor, with a separate field winding for each phase. It can be used as a 2 phase motor with the phases separated by 90 degrees. The second phase is derived from the supply using a capacitor or inductor to cause the current to lead or lag by approximately 90 degrees. The inductor type might use the different inductance of the two windings to get some current separation, and so the starting torque might be lower as this is less than 90 degrees. These were popular because capacitors were expensive. The capacitor type has a capacitor in series with the start winding, and is the most likely type nowadays. Once the rotor is up to speed the start winding can be disconnected by a centrifugal or current operated switch. Some motors run with both windings continuously connected. Another principle now out of favour because of efficiency issues is used on small motors like fans. It is called a shaded pole motor. Here a special shading pole, part of each stator field pole, is fitted with a shorting winding which causes the field to shift as it builds up on each half cycle, so there is a flick in the correct rotational direction. This has low starting torque.
Are there energy efficient exhaust fans?
Most manufacturers and wholesalers of exhaust fans carry energy efficient models. When looking for a fan which will save energy, look for the "Energy Star" logo which shows that the products meets energy efficiency guidelines.
What are objectives of mechatronics?
Mechatronics is a manufacturer of cooling fans and blowers in both AC and DC models. They aim to deliver a product with great quality at a highly competitive price.
What are industrial applications of DC shunt motors?
Dc shunt motor is a constant flux and constant speed motor . So that it is used in centrifugal pumps ,machine tools ,blowers and fans etc.
What are ceiling fan capacitors for?
There are a variety of capacitor sizes in ceiling fans. The capacitor is dependant upon the characteristics of the fans motor. Whether it is a single speed, two speed or three speed. If you think it is the capacitor at fault for the fan not operating, take the fan down and open it up. This will give you the exact sizing for your fan.See sources and related links below.
How fast can a fan go?
Most 110 volt household fans will rotate at 1725 rpm as that's a standard motor speed. Some specialised fans like those for computer mainframes may rotate faster.
Does table fans have capacitors?
The capacitors used in table fans is to start its induction motor.
Why would blower motor come on when ignition is off?
Is it the blower motor or is it the fans in the front?if its the fans they will come on at anytime to help cool engine down better.If its the blower motor for the interior heat and air you got a electrical problem.

If it is the blower motor for your heater then it is definatly you blower resistor
What is the function of vfd?
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.
Which motor is used in ceiling fans?
Single phase induction motors are used in ceiling fans
What happens if you use synchronous motor in ceiling fans?
Synchronous motors are much more efficient at converting electric power into motion. However, the speed of the motor is controlled by the frequency of the electric supply. So a synchronous motor ceiling fan would be much more efficient, but the speed of the fan would not be controllable, unless frequency controlled power supplies (inverter power) are used.
Why does only one speed work on blower motor on 2003 Chevy trailblazer?
Its probably starting to burn out. Frequently the fans spin so much and wear out. time for a new one!
Does ceiling fan consume less electricity on high speed?
Ceiling fans use less electricity on low speed than they do on medium and high speed. Capacitors are used to control the various fan speeds. The capacitor limits the amount of electricity supplied to the fan motor. When less electricity is sent to the windings in the motor, the fan spins at a lower RPM. The result is a slower speed and less airflow. However, some fans move almost no air at low speeds, so it is important to know what the CFM/watts is for the ceiling fan in question so you can compare the performance at any given speed relative to the amount of electricity used
What are fans powered by?
Most fans have an electric motor that runs off of electricity. These use magnetization to spin the fan
What type of DC motor fan use?
shunt type dc motor use in train fans
