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.
Materials for producing 2900 rpm motor is less than 1450 rpm one
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
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.
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
Induced voltage is increased
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.
The mean rotational speed of a ceiling fan is typically measured in revolutions per minute (RPM). The average RPM of a ceiling fan can vary depending on the specific model, but it is commonly around 150-250 RPM for normal operation.
The speed of a ceiling fan is typically measured in revolutions per minute (RPM). A typical ceiling fan may have speeds ranging from around 50 to 200 RPM on the low setting, and up to 200 to 300 RPM on the high setting.
Ranges from 250 to 450 rpm.. If there is need to increase the speed then the rpm is eventually increased as per the need
To get the fan rotating faster than the motor driving it, gears are needed.

The speed of a pedestal fan can be verified by using a tachometer to measure the revolutions per minute (RPM) of the fan blades. Alternatively, you can use a stopwatch to time how long it takes for a point on the fan blade to complete a full rotation. This can then be used to calculate the RPM of the fan.
The most common way to measure a fan's RPM (revolutions per minute) is by using a tachometer. This device uses a sensor to detect the fan blades' rotation and calculates the RPM based on the number of rotations per minute. Another method is to use software that monitors the fan speed through the computer's hardware monitoring system.
Cooling fan RPM error.
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.

When the load on the engine is increased, the engine RPM typically decreases because the engine has to work harder to overcome the additional resistance. This is due to the increased demand for power output to maintain the same speed or acceleration.
