How do you calculate the force of a motor?

To calculate the force required to move the object: F = m * g *u , F = force, m = mass of object, g = gravity constant, u = friction. F = 500 kg * 9,82m/s2 * 0.8 F = 3924 N to push the object. That must be right.

How do you calculate motor shaft force?

For example, if you want to hold the force acting on the end of pulley, T = F x r. So calculating load torque is determine the force in the system and the logical distance between the motor shaft and the where the force is acting.

How do you calculate the power of a DC motor?

Power Equation of a DC Motor

  1. VIa = Input Power supply (Armature Input)
  2. EbIa = Mechanical Power developed in Armature (Armature Output)
  3. Ia2 Ra = Power loss in armature (Armature Copper (Cu) Loss)

What is motor torque formula?

Torque (N.m) = 9.5488 x Power (kW) / Speed (RPM) Power (kW) = Torque (N.m) x Speed (RPM) / 9.5488.

How do you calculate motor power from RPM?

To calculate RPM for an AC induction motor, you multiply the frequency in Hertz (Hz) by 60 — for the number of seconds in a minute — by two for the negative and positive pulses in a cycle. You then divide by the number of poles the motor has: (Hz x 60 x 2) / number of poles = no-load RPM.

What is J in torsion formula?

General torsion equation

J = polar moment of inertia or polar second moment of area about shaft axis, [m4, in4] τ = shear stress at outer fibre, [Pa, psi] r = radius of the shaft, [m, in]

How do u calculate force?

What is the formula for force? The force formula is defined by Newton’s second law of motion: Force exerted by an object equals mass times acceleration of that object: F = m ⨉ a. To use this formula, you need to use SI units: Newtons for force, kilograms for mass, and meters per second squared for acceleration.

How do I calculate RPM?

RPM = a/360 * fz * 60

RPM = Revolutions per minute. Example 1: Drive step resolution is set for 1000 steps per revolution. Example 2: Drive step resolution is set for 500 steps per revolution. With input frequency of 1000hz, .

What is 120 in motor speed formula?

The equation for calculating synchronous speed is: S = 120 f/P speed = constant (120) times frequency of power source (60 Hz) divided by number of poles used in the motor (P).

How much weight can a 12V DC motor lift?

Weight: 100 gm(Approx.) RPM: 100 Operating Voltage: 12V DC Gearbox: Attached Plastic (spur)Gearbox Shaft diameter: 6mm Shaft Length: 21 mm Torque: 1.2 Kg-cm. No-load current = 60 mA(Max) Load current = 300 mA(Max).

What is the formula to calculate torque?

Mathematically, torque can be written as T = F * r * sin(theta), and it has units of Newton-meters. When the sum of all torques acting on an object equals zero, it is in rotational equilibrium.

What is Torque in physics definition?

Torque is a measure of how much a force acting on an object causes that object to rotate. The object rotates about an axis, which we will call the pivot point, and will label ‘O’. We will call the force ‘F’.

Is torque directly proportional to RPM?

Because torque and RPM are divided by 5252, torque and horsepower are equal when the engine speed is equivalent to 5252 RPM, while torque is greater than horsepower below 5252 RPM and horsepower is greater than torque above 5252 RPM.

What is the formula to calculate horsepower?

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.

What is the rpm of 1 hp motor?

1HP 750 W 1 HP 3000 RPM Three Phase AC Induction Motor

Power 1HP 750 W
Speed (RPM) 1440,2880
Voltage 230

What is the formula for RPM on a lathe?

The following equation is used to cal-culate spindle speed: rpm = sfm ÷ diame-ter × 3.82, where diameter is the cutting tool diameter or the part diameter on a lathe in inches, and 3.82 is a constant that comes from an algebraic simplifica-tion of the more complex formula: rpm = (sfm × 12) ÷ (diameter × π).
