Electric Motor Gearbox Rpm Calculator

At no load you have maximum speed and zero torque.

Electric motor gearbox rpm calculator. Gear motors have gear reduction transmissions built into them with shaft output speeds commonly between 400 550 rpm. Related mobile apps from the engineering toolbox. Your source of power is let say an electric motor. Calculating the rpm resulting from a motor and speed reducer assembly requires only basic mathematical knowledge.

We want to see your websites and blogs. Rounded to the nearest 10 000th 100 promotion. The torque delivered from an electrical motor producing 0 75 kw 750 w at speed 2000 rpm can be calculated as. Pulley and speed calculator.

For example if your small pulley is 80mm diameter and spins at 1000 rpm and you need to find the second pulley size to spin it at 400 rpm enter pulley1 80 pulley 1 rpm 1000 pulley 2 rpm 400 and. Rla running load amps current drawn during normal operation of electric motor. Below is a small calculator that will solve the ratio for you. Calculated out this gives an output torque of 3 500 in lbs and an output speed of 571 4286 rpm.

Motors run at a specific revolutions per minute rpm and a speed reducer is needed if you want to keep that motor but have a lower rpm. Enter any 3 known values to calculate the 4th if you know any 3 values pulley sizes or rpm and need to calculate the 4th enter the 3 known values and hit calculate to find the missing value. If you have any problems with the pulley calculator please email us. Fla full load amps amount of current drawn when full load torque and horsepower is reached for the motor fla is usually determined in laboratory tests note.

Finally now that we have verified that our gear ratio satisfies our requirement we can calculate how long it should take for the motor to raise the elevator. If you need to amplify the motor torque with a factor of 3 then you need a gear reducer with a 3 0 gear ratio. In our example input electrical power of the motor is 0 22 a x 6 v 1 32 w output mechanical power is 1000 rpm x 2 x 3 14 x 0 00126 n m 60 0 132 w. 1750 rpm 1000 rpm 3 5 inches d 2 d 2 6 125 inches.

We have now completely verified that our rs 550 motor and 26 1 gearbox will achieve or exceed our original goals. Between the motor and the pump we fit the gear reducer. The torque delivered from an electrical motor producing 100 hp at speed 1000 rpm can be calculated as. Check the circle next to the item you are solving for and enter the remain three items in the spaces provided.

Standard motors and gear motors. T 750 w 9 549 2000 rpm 3 6 nm example torque from an electrical motor. 1 hp 0 745 kw. Win 100 towards teaching supplies.

Output rpm 2000 3 5. Scientific calculator simple calculator. Example torque from an electrical motor. How do we calculate the gear ratio.

There are two types of electric motors. Standard motors have shafts directly attached to the motor windings with shaft output speeds commonly between 1800 3000 rpm.
