How do you choose a torque for a servo motor?
Therefore, the total torque requirement for a servo is:
- Torque Required By a Servo Motor = (Torque Due to Force of Gravity on Links and Payload) + (Torque Due to Angular Acceleration of Links and Payload)
- τ = Iα
- τ = Iα
- τ = 1.414 kg-m2/s2 = 1.414 Nm = 14.410 kg-cm = 200 oz-in.
Does servo motor have high torque?
As a result, they must be run closed-loop. In general, servo motors are more sophisticated than stepper motors. This enables servo motors to be used with gearboxes to deliver much higher torque at useful speeds. They also deliver more consistent torque across the speed range of the motor.
What is servo motor torque?
Servo motor torque curves are relatively flat up to the motor’s maximum speed, unlike stepper motors, whose torque drops sharply beyond a certain operating speed. The maximum torque required by the motor is typically the sum of torque during acceleration, torque due to the load, and torque to overcome friction.
What does the torque curve on a servo mean?
Accordingly, the servo motor torque curve, which depicts the amount of torque a motor can produce over its range of operating speeds, is one of the most useful tools in servo motor sizing and selection. The servo motor torque curve shows two operating zones—continuous and intermittent.
When to use a force sensor in a servo motor?
Use a force sensor at a known distance by multiplying the distance by force minus any known variables or inaccuracies. Torque curves are common and simple visual representations that explain a lot about a servo motor’s torque performance.
What is the difference between the holding torque and stall torque?
The information on torque for these stepper motors is given as holding torque. While these servo motors have the torque given as stall torque. My hope is to use the maximum torque a motor can handle to compare different motors for a project.
How are servo motors different from stepper motors?
Servo motors have two operating zones: continuous duty and intermittent (peak) duty. Servo motor torque curves are relatively flat up to the motor’s maximum speed, unlike stepper motors, whose torque drops sharply beyond a certain operating speed.
