Electric Motor Gearbox Rpm Calculator

At no load you have maximum speed and zero torque.

Electric motor gearbox rpm calculator.

Between the motor and the pump we fit the gear reducer. Standard motors and gear motors. Gear motors have gear reduction transmissions built into them with shaft output speeds commonly between 400 550 rpm. 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.

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. Standard motors have shafts directly attached to the motor windings with shaft output speeds commonly between 1800 3000 rpm. We have now completely verified that our rs 550 motor and 26 1 gearbox will achieve or exceed our original goals. Calculating the rpm resulting from a motor and speed reducer assembly requires only basic mathematical knowledge.

Example torque from an electrical motor. 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. Rounded to the nearest 10 000th 100 promotion. 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.

Win 100 towards teaching supplies. 1 hp 0 745 kw. In order to calculate the gear ratio of the two meshed gears we need to know either. Your source of power is let say an electric motor.

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. Pulley and speed calculator. Below is a small calculator that will solve the ratio for you. The torque delivered from an electrical motor producing 0 75 kw 750 w at speed 2000 rpm can be calculated as.

1750 rpm 1000 rpm 3 5 inches d 2 d 2 6 125 inches. 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. Scientific calculator simple calculator. Rla running load amps current drawn during normal operation of electric motor.

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. The torque delivered from an electrical motor producing 100 hp at speed 1000 rpm can be calculated as. Related mobile apps from the engineering toolbox. Calculated out this gives an output torque of 3 500 in lbs and an output speed of 571 4286 rpm.

Output rpm 2000 3 5. If you have any problems with the pulley calculator please email us. T 750 w 9 549 2000 rpm 3 6 nm example torque from an electrical motor. Motor torque changes with the speed.
