What are the ratings on the label plate of your motor? I got the 1 horsepower and the 1750 rpm, but what is it rated for in cycles per second, or Hertz?
Regardless of the horsepower rating or the rpm, AC motors are designed to run on a specific frequency of alternating current sine wave.
Without some sophisticated and expensive equipment, you cannot change the frequency (Hertz) of your incoming electrical supply. What is recommended by me is to buy a motor that matches your power and speed requirements, and make very sure that its frequency rating is the same as your power utility supplies. If you live in the U.S.A. or Canada, the supplied frequency is 60 Hz.
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.

One way would be to hook it up to a supply (by itself, with no load) and measure the speed with a contact tachometer. If your supply is 60Hz, and the motor speed corresponded to one of the standard motor speeds, it would be a pretty safe bet you had a 60Hz motor. If the speed was about 20% faster than a standard speed, the motor is probably a 50Hz motor. Or 20% slower if you were running a 60Hz motor on 50Hz For instance, a 1750 RPM 50Hz motor would spin at about 2100 RPM if you ran it on 60Hz.
25% of 1750= 25% * 1750= 0.25 * 1750= 437.5
There were few jobs available to women who lived during the 1750s. These included running a shop and teaching children.
1750
1750 would be written as MDCCL
1750
1750 x .03 = 52.5So 52.5 is 3% of 1750.
4 times what equal 1750
9.50 * 1750 = 16625
It is: 1750 = MDCCL
