Best answer: What is the maximum torque on the motor

1 Answer. Torque of a motor is directly proportional to current. Therefore, the maximum torque a motor can produce is limited by the maximum current it can handle. The maximum steady state current a motor can handle is limited by the heat it can safely dissipate, which is proportional to the square of the current.

What is the maximum torque?

Torque is defined as τ = rF sin θ, where F is the force, r is the distance from the pivot that the force is applied, and θ is the angle between r and F. … (b) The maximum torque occurs when θ is a right angle and sin θ = 1.

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.

How do you find maximum torque?

Note that the torque is maximum when the angle is 90 degrees. A practical way to calculate the magnitude of the torque is to first determine the lever arm and then multiply it times the applied force. The lever arm is the perpendicular distance from the axis of rotation to the line of action of the force.

What is full load torque of motor?

Full-load (Rated) Torque or Braking Torque

The Full-load Torque is the torque required to produce the rated power of an electrical motor at full-load speed.

Does more torque mean faster acceleration?

A car with more hp than torque will always be quicker since this gives a car acceleration and speed. … Higher torque doesn’t mean one vehicle will necessarily be faster than another, though. For example, a Ford F-250 makes 925 lb-ft of torque, while a Honda S2000 has just 162 lb-ft.

What force does not cause any torque?

Any force that is along a line which passes through the axis of rotation produces no torque. Note that torque is a vector quantity, and, like angular displacement, angular velocity, and angular acceleration, is in a direction perpendicular to the plane of rotation.

What is the torque of a motor?

The torque is the twisting force that makes the motor running and the torque is active from 0% to 100% operating speed. The power produced by the motor depends on the speed of the motor and is. zero at 0% speed, and. normally at it’s top at operating speed.

How much torque does a 1 hp motor have?

The definition of 1 Horsepower is displacing 1 lb. 33,000 ft. in one minute or 33,000 lb-ft / minute.

How do you check motor torque?

To measure the torque simply create a transversal arm attached to the motor using a known length. Let the whole motor free to turn (not the shaft, the outside case) along with the attached arm. The arm tip, opposed to where it’s attached to the motor, can then be placed on a balance.

Is the higher the torque the better?

Because there is generally a limit on how fast you can spin an engine, having higher torque allows for greater horsepower at lower rpms. This is also why people talk about “low-end torque” being important for better power at slower speeds.

Can a single force produce a zero torque?

A single point force not acting at the COG, will always provide a torque but this torque will be accompanied by a net linear force as well since there is no opposing force. So, the net motion will be a combination of rotational and linear motion.

How do you calculate torque distance?

In high schools the formula is usally shown as “torque=force*distance” because we assume that there is a right angle between the force and the lever arm. The other formula is more general, and takes into account when the angle theta is not 90 degrees (sin90=1).

What is pull out torque?

The maximum torque that can be applied to a motor operating at a given speed without losing synchronism.

How much torque is required to lift a weight?

To calculate load torque, multiply the force (F) by the distance away from the rotational axis, which is the radius of the pulley (r). If the mass of the load (blue box) is 20 Newtons, and the radius of the pulley is 5 cm away, then the required torque for the application is 20 N x 0.05 m = 1 Nm.

How do you increase the torque of a motor?

If you want to adjust the output torque within the rated torque range, you can usually adjust the input voltage or the amount of excitation current. If the DC motor has been set, the torque can only be increased by the speed reducer, which can be multiplied or even increased by a thousand times.
