## How do you calculate HP?

Power = (Force x Distance) / Time For electric motors, power or horsepower can be calculated from the torque and speed.

For example, if you have a motor rated for 3,000 RPM and 6 in-lbf then the horsepower is calculated below..

## How do you calculate starting torque?

We know that at the start the rotor speed, N is zero. So, the equation of starting torque is easily obtained by simply putting the value of s = 1 in the equation of torque of the three phase induction motor, The starting torque is also known as standstill torque.

## How do you calculate maximum torque of a motor?

Multiply the horsepower by 5,252 using a calculator. Using the example figure, multiply 0.6434316 by 5,252 to get 3,379.3027. Divide the answer by the motor’s rated number of rpm to get the measurement of the torque in pound-feet.

## What is the power consumption of lift?

one unit costing 7–10 Rs. is 1 kwh. So if a 3.75 kw motor runs for 1 hour it will consume 3.75 units of electricity. To run 1 hour the lift can make 240 trips one way for 4 floors or it can go up and down 120 times.

## How much torque is required to move a car?

Overall transmission (and power-train) efficiency of the modern electric vehicles is within 59 .. 62 %. The answer to your question is 43.2 Nm of Torque required that can be obtained with the transmission ratio value of 15.

## How do I calculate motor power to lift 150 kg?

There are two formula;P = (T × N) /9550.P = (F × V) / 1000.

## How do you calculate the lifting capacity of a motor?

Force needed to hold 100 kg against gravity = 100*9.8, rounding it up to 1000N. Let’s say the machine lifts it up at a rate of 1 meter per second. So power needed would be 1000 x 1 = 1kW.

## How do you calculate torque needed?

The required torque is calculated by multiplying the sum of load torque and acceleration torque by the safety factor. When the required torque for the motor varies over time, determine if the motor can be used by calculating the effective load torque.

## How long will it take a 2.5 KW motor to lift a 80 kg block 30 m high?

Motor will take 9.4 s to lift block. Work done by motor to lift block is equal to change in gravitational potential energy of block.

## Which motor is used in lift?

AC slip ring or DC compound motors are prefer for lifts. Shunt type commutator motors are preferred in case of single phase installation. The latest lift designs use 3-phase induction motors with variable frequency drive electronic controls.

## How much weight can a 1/2 hp motor lift?

To find the weight each opener can lift simply divide 550 lbs by the manufacturer HP rating and then multiply by (2/3). For example, a 1/2 horsepower garage door opener should be able to lift 275 pounds while a 1 HP opener can lift 550 pounds.

## How much weight can a 1 hp motor lift?

about 550 lbsThis means with 1 hp, you can lift about 550 lbs (250 kg) at a rate of 1 ft/sec, 1100 lbs at a rate of 0.5 ft/sec, 225 lb at a rate of 2 ft/sec, 1 lb at a rate of 550 ft/sec, and so on.
