That depends on the type of fan. If it's a belt driven fan, you should be able to change the drive belt pulleys.
If it's a direct drive fan, you'll need to change the motor.
Note an exception: some direct drive fan motors have multiple connection points which provide different operation speeds. When the cover plate is removed, there is typically a chart showing how to wire the motor for different speeds. If you see no such chart, you probably cannot change the speed of the motor.
Also note: most modern fan motors are synchronous type, meaning that they control their speed from the fact that alternating current feeds the motor. If you change the input voltage it will not change the speed, but may destroy the motor. If the motor does not have brushes, you cannot use a motor speed control.

Why 2900 rpm motor is less price than 1450 rpm motor?
Materials for producing 2900 rpm motor is less than 1450 rpm one
A 6 pole induction motor is connected to a 415v50hz mainsIt runs at a speed of 960 rpmCalculate the answer of synchronous speed?
Answer 1000 RPM or 16.667 HZ, 50 Hz * 60 = 3000 RPM 3000 / 3 = 1000 RPM, or 50 HZ / 20 (1/3 of 50 Hz) * 60 seconds. Or Hz * 20 ( converts to RPM) For 4 pole then, Hz * 30 = RPM For 8 pole, Hz * 15 = RPM
How many poles in a six thousand RPM motor?
It depends on the frequency. At 60 Hertz, with an ordinary two pole synchronous motor, you cannot have an RPM that is greater than 1800, so a six thousand RPM motor has to have a different power supply.
When coil turns are increased the?
Induced voltage is increased
Is the torque output of a DC motor directly proportional to armature current?
In dc shunt motor,base speed is 500 rpm and its field current is 17A, top speed is 1200 rpm and field current is 5.6 A.But 600 rpm it has reduced by 10A It is normal? How
What is the mean of RPM in the Ceiling Fan speed?
Mean of rpm is in fan is that in a minute how much revulation is completed by a fan.
A fan running at 1250 rpm and one running at 1750 rpm what giving delivering more cfm's?
1. ASSUMING AIR DENSITY AND FAN BLADE DIAMETER IS CONSTANT OR THE SAME --THE LATTER (1750 RPM) DELIVERS MORE CFM WHETHER BELT DRIVEN OR DIRECT COUPLED -- SAME HP RATING OF MOTOR. 2. 1250 RPM FAN CAN MATCH THE CFM OF 1750 RPM FAN --- CHANGE OR ADJUST THE PITCH OF 1250 RPM FAN BLADE. 3. 1250 RPM FAN CAN DELIVER MORE CFM THAN THE 1750 RPM FAN --- REPLACE FAN BLADE. 4. 1250 RPM FAN CAN DELIVER MORE CFM THAN THE 1750 RPM FAN --- REPLACE WITH BIGGER HORSE POWER.
What is the speed in RPM of a ceiling fan?
945 rpm
What RPM does a helicopter blade spin at?
Ranges from 250 to 450 rpm.. If there is need to increase the speed then the rpm is eventually increased as per the need
What happens when the motor rpm is less than the fan rpm of an air handling unit?
To get the fan rotating faster than the motor driving it, gears are needed.
What is the speed for processor fan?
cpu fan speed of 3590 RPM normal(CPU 73c)
What is a DTC P1484 for a 2002 Envoy?
Cooling fan RPM error.
How many rotation can a fan make in 1 hour?
IF the fan speed in RPM is given, multiply this figure by 60 to find the number of rotations the fan makes in an hour.
If speed of fan is increased is energy consumption increases or decreases?
Energy consumption increases due to the increased air mass flow brought about by higher fan speed.
What causes rpm fluctuation on 2002 dodge ram?
bad radiator fan cluth...
Why would Engine temperature increase at idling?
Because the efficiency of the fan and the water pump degrades at low RPM.
What happens to the engine RPM when load is increased?
If the load you are talking about is weight not load to the engine. It will take more power to pull or haul. So RPM will go up while speed increases only marginally.
