Electric motor gearbox rpm calculator.

Between the motor and the pump we fit the gear reducer. 1 hp 0 745 kw. Rla running load amps current drawn during normal operation of electric motor. If you have any problems with the pulley calculator please email us.

At no load you have maximum speed and zero torque. Scientific calculator simple calculator. 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. 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.

Related mobile apps from the engineering toolbox. Example torque from an electrical motor. Calculating the rpm resulting from a motor and speed reducer assembly requires only basic mathematical knowledge. Rounded to the nearest 10 000th 100 promotion.

In the calculator above fla is rla 25. Your source of power is let say an electric motor. We have now completely verified that our rs 550 motor and 26 1 gearbox will achieve or exceed our original goals. The torque delivered from an electrical motor producing 100 hp at speed 1000 rpm can be calculated as.

Standard motors have shafts directly attached to the motor windings with shaft output speeds commonly between 1800 3000 rpm. Check the circle next to the item you are solving for and enter the remain three items in the spaces provided. 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. Pulley and speed calculator.

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. 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. Win 100 towards teaching supplies.

There are two types of electric motors. Gear motors have gear reduction transmissions built into them with shaft output speeds commonly between 400 550 rpm. Below is a small calculator that will solve the ratio for you. Standard motors and gear motors.

T 750 w 9 549 2000 rpm 3 6 nm example torque from an electrical motor. How do we calculate the gear ratio. In order to calculate the gear ratio of the two meshed gears we need to know either. 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.

Calculated out this gives an output torque of 3 500 in lbs and an output speed of 571 4286 rpm. The torque delivered from an electrical motor producing 0 75 kw 750 w at speed 2000 rpm can be calculated as.
