RPM is a short-form of Revolutions Per Minute (RPM). It is a unit of rotational/ angular speed that indicates the rate of revolution of the rotor component i.e., the number of full rotations the rotor makes per minute. Simply, RPM is a measure used to describe the rotational speed of the motor’s spindle/motor shaft.
What is the RPM of 1 hp motor?
The 3600 RPM, 1HP motor produces 1.5 ft. lbs. of torque at 3600 RPM.
What determines motor RPM?
The number of poles, combined with the ac line frequency (Hertz, Hz), are all that determine the no-load revolutions per minute (rpm) of the motor.
What is the rpm of 0.5 hp motor?
1500 RPM
Havells – Havells 0.5 HP Single Phase Motor, 1500 RPM, 4 Pole Foot Mounted.
What is the rpm of 1.5 hp motor?

How many RPM is a 10 pole motor?
600 rpm
A: A 10-pole motor would have 5-pairs of N-S poles. It would rotate at 50/5 = 10 rotations per second or 600 rpm (10 s-1 x 60 s/minute).
How many RPM is a 4 pole motor?
1800 rpm
Two pole AC motors operating at 60 Hz will always run at approximately 3600 rpm, and four pole AC motors will have speeds around 1800 rpm. Example 120 x 60 hertz / 4 poles = 1,800 rpm.
How do you calculate RPM speed?
Multiply the circumference by the object’s angular speed, measured in rpm. For example, if it rotates at 400 rpm: 87.98 × 400 = 35,192. This is the object’s surface speed, measured in inches per minute. Divide this answer by 63,360, which is the number of inches in a mile: 35,192 ÷ 63,360 = 0.555.
How do you calculate RPM on a 3 phase motor?
Calculating RPM for a three phase induction motor is relatively simple… ACThree Phase Induction MotorRPMis determined by the formula: RPM = (120 * Frequency) / # of poles in the motor.
How do you calculate RPM from engine RPM?
To convert vehicle speed to a wheel’s RPM:
- Multiply wheel’s RPM by the tire diameter.
- Multiply the product by 60 and π.
- Divide the resultant by 63360.

What is a 3 phase motor?
Three-phase motors are a type of AC motor that is a specific example of a polyphase motor. These motors can be either an induction motor (also called an asynchronous motor) or a synchronous motor. The motors consist of three main components – the stator, the rotor, and the enclosure.

How many RPM is 60 Hz?
Hertz to Revolution Per Minute Conversion Table
| Hertz | Revolutions Per Minute |
|---|---|
| 1 Hz | 60 RPM |
| 2 Hz | 120 RPM |
| 3 Hz | 180 RPM |
| 4 Hz | 240 RPM |
How do you calculate RPM from a pole?
Poles = number of poles of your motor. So, for example, if you have a 4 pole motor on 60 Hz then RPM=60*(2/4)*60=1800 rpm.
How do you tell if a motor is 2 pole or 4 pole?
On an induction motor, the number of poles determines the speed given the frequency of the power. For a 2 pole motor, at 60hz, it will spin 60 times a second, or 3600rpm. For a 4 pole motor, the speed is halved – 1800 rpm, 6 pole, 1200 rpm and so on.
What is the rpm of a 8 pole motor?
| Approximate Electrical Motor Speed (rpm) | ||
|---|---|---|
| No. Poles | Speed with Rated Load | Synchronous Speed (no Load) |
| 4 | 1725 | 1500 |
| 6 | 1140 | 1000 |
| 8 | 850 | 750 |
What is the maximum rpm of an electric motor?
The most common speeds of electric motors are 3000RPM for 2 pole asynchronous motors. If connected to frequency drives and the motor is designed mechanically for higher speeds they can go to 6000RPM.
What is RPM of induction motor?
