How to calculate the pulling force of the motor

1. Friend, the calculation formula of motor torque T = 9550p / N, P is power, unit is kW, n is speed, unit is rpm, R / min, torque unit is nm.

2. Formula: 9550 times the rated power of the motor divided by the motor speed = torque (n / M)
on this basis, divided by 9.8, we can get how many kilograms of weight the motor can pull
rated torque of motor
t (N.m) = (9550 × P ÷ N
t (N.m) / 9.8 = load (kg)
P: motor rated power
n: motor rated speed
t: torque (n / M)

3. Here I don't know the weight of your gate, the friction of the track and the wheel, so I can't give you the exact data
but it can be calculated by the following method: measure how much force F is needed to pull the door (use a dynamometer or homemade spring). F unit is Newton, and then estimate the opening speed V (generally 0.15m / s). The proct of the two is the actual power required, and then consider some other factors such as wind pressure and loss of transmission mechanism, Multiply by a safety factor of 1.3-1.5
P = (1.3-1.5) * f * V
this is a calculation method, and also a measurement method: find the motor you have (the power is from 300W to 1.5KW) and take it to the gate to work. Use a clamp meter to measure the current I, then I / 2 is the actual power required. Of course, consider the safety overload factor.

4. If a person wants to push an object, then the force F given to the object should be equal to or greater than the friction f between the object and the ground, that is, the steps should be like this! In order to make the object move, f = f (friction) and f (friction) = mg * u (U is the friction coefficient) can be solved by numerical method.

5. Motor output is mechanical power, work is also multiplied by the ration. Power = torque times speed.

6.

Motor torque:

the calculation formula is:

t = 9549 × P ÷ The unit of n is n & 8226; M (nm)

where: P rated power of motor (output power), kW

n rated speed of motor, R / min

specific calculation of speed n:

when the rotating magnetic field has

extended data:

generally speaking, the torque of motor with mechanical rotation is the torque of motor

Note: the torque of the motor is directly proportional to the strength of the rotating magnetic field, the current in the rotor cage bar, and the square of the power supply voltage, so the torque is determined by the factors of current and voltage

7. The balance method is used for uniform linear motion or static motion; Newton's second law for variable speed motion

8. Your principle is the same as that of some building construction units when they lift concrete up and down. If the center of the circle reaches AB, they should not participate in the work. As shown in the figure, according to the positive and negative rotation of the motor, the object rises and falls through the pulley, while the single set of fixed rollers are used. The force does not change, so the force on both sides of the pulley is equal. Assuming that the object rises, the work done by the motor is converted into tension in the ideal state, So, g = m * g, you know
hope to adopt it!

9. It's too difficult. It's astronomical to me.

10. How does this work
water or vertical
do you want the load of the motor to match the motor well?
