![]() ![]() The gear ratio is the measure to which the device amplifies rotational force, while decreasing revolution rates. The needed rating is the distance times force minus inaccuracies.Ī possible remedy to get a servo motor with high torque is to add a gearhead-an arrangement of gears ensuring proportional speed-to-torque conversion. Quantifying torque against speed is the major advantage of the methodology.Ī third technique is to make calculations based on the force sensor measurements taken at an established distance. Relying on the measurement results, calculate velocity and acceleration and use the inertia moment to find out the required value. To apply the method, couple a large load with known inertia moment to the actuator. It is also possible to derive the rating from the position or velocity sensor readouts. Don't forget to count in errors due to inaccurate coupling alignment. In the case, measurement accuracy depends on correct instrument settings. One option is to fix a gauge onto an engine shaft and read measurements while running the engine. There are several ways to measure how high torque is: How much turning force a servomechanism can output depends on design factors-supply voltage, shaft speed, etc. In the specifications of linear models, the ability to move objects is defined by force.įor a servo motor, high torque means a mechanism is able to handle heavier loads. With regard to a servo motor, the technical term defines the mechanical work produced by its shaft spinning, typically measured in Newton-meters (Nm). The equation has a positive result if rotation is in the anticlockwise direction or a negative outcome when an object turns clockwise. ![]() General definitionĮxpressed as a formula, torque is the twisting action applied perpendicular to a distance vector times the vector length from the reference datum of impact to the pivot point. Let's look at how the high torque properties match up with the servomechanism inner workings and critical metrics, such as inertia ratio and rotation rates. Providing performance and accuracy equivalent to steppers, servo motors demonstrate a bigger torque generation potential, while featuring impressive model lineups-from nano servos to high torque modifications. ![]()
