Question: How is motor stall torque calculated?

How do you calculate torque from stall torque?

You can estimate the rated torque as 20%-30% of the stall torque. For example, if your robot requires 0.5Nm torque, you would need a motor with a stall torque rating of 1.6-2.5Nm.

What is motor stall torque?

Stall torque is the torque produced by a mechanical or electro-mechanical device whose output rotational speed is zero, whereas torque can be defined as the mechanical work generated by the turning effect produced when force is applied to a rotational axis.

How is motor torque measured?

A relatively simple method to estimate electrical motor torque is to measure its electrical power input, the voltage and the current in the power line driving the motor. For most motors, torque is directly proportional to the current and can be derived from it by knowing shaft speed and motor efficiency.

Is stall torque the same as holding torque?

Both holding torque for a stepper motor, and stall torque for a servo motor, refer to the maximum amount of torque when the shaft is not spinning and the windings are fully energized. A stepper motor also has a detent torque because of its magnet arrangement.

What is Peak stall torque?

Continuous stall torque is the motor’s continuous torque at 0 speed (at stall). … Peak torque is the motor’s maximum torque it can output for a short period of time, typically for acceleration/deceleration or overcoming friction.

What is stall torque and stall current?

From Wikipedia, the free encyclopedia. Stall torque is the torque produced by a mechanical device whose output rotational speed is zero. It may also mean the torque load that causes the output rotational speed of a device to become zero, i.e., to cause stalling.

How do you calculate maximum torque of a motor?

Calculate torque (T) using the formula T = 5,252 x horsepower/rpm. The results are measured in pound-feet. For example, if you have a 40-horsepower motor designed to operate at a peak of 1,200 rpm, the formula would be T = (5,252 x 40)/1200 = 175.07 lb. -feet.
