RPM is equal to (120 x frequency)/number of poles in the motor. Take the necessary measurements. Find the frequency of the motor in hertz. Most commercial motor operate at between 50 and 60 hertz. In addition, count the number of winding poles inside the motor. Multiply by the constant. Multiply the motor's frequency by the constant 120.

• ### Mechanical Gear Ratio Calculator for Output

Example: A gear increaser with 1000 in/lbs of input torque, an input speed of 2000 RPM, and a ratio of .20:1 is: Output Torque = 1000 x .20. Output RPM = 2000 / .20 . Calculated out this gives an output torque of 200 in/lbs and an output speed of 10,000 RPM. (rounded to the nearest 10,000th)

• ### How A Gear box (Transmission) works? What's

The driving gear and driven gears in a gear box define the gear ratios. The input gears get the drive from the engine and they rotate the output gears which, in turn, drive the wheels. The ratio of the number of rotations of output gear to the number of rotations of input gear is called Gear Ratio.

• ### Working out Revolutions Per Minute

Below are examples of the way to work out 'revolutions per minute', or RPM as it is usually called. In the example below the DRIVER gear is large than the DRIVEN gear. The general rule is - large to small gear means 'multiply' the velocity ratio by the rpm of the first gear. Divide 60 teeth by 30 teeth to find

• ### Ball mill - Wikipedia

A ball mill is a type of grinder used to grind, blend and sometimes for mixing of materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering.It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotati

• ### How to Determine Speed for an Ac Induction

Illustration of a six-pole stator. One way an hvacr service tech can determine that s/he is making good motor replacement decisions in the field is to understand the concept of motor speed so that the speed of one ac induction motor can be matched to another. At the same time, techs also need to become familiar with the concept of poles, since poles represent one key to a successful replacement.

• ### How A Gear box (Transmission) works? What's

The driving gear and driven gears in a gear box define the gear ratios. The input gears get the drive from the engine and they rotate the output gears which, in turn, drive the wheels.
