How does voltage affect torque?
More voltage=More electromagnetic=more power=more torque. More current is not equal to more torque.
Does torque depend on voltage?
Back to the original question: how does voltage affect speed? From the analysis above, we can see that when the load (torque) on the motor is constant, speed is directly proportional to supply voltage. And, when the voltage remains constant, an increase in the load (torque) on the motor results in a decrease in speed.
Will motor torque always increase with voltage?
Torque comes from more power. Power is directly related to amps and volts.. as a result, increasing voltage increases torque.
What does intermittent torque on a motor mean?
The intermittent torque zone just means that you can’t run the motor in that area continuously without the motor getting too hot for the insulation system. There are a number of reasons that the speed-torque curves in Figs. 1 and 2 look different.
What does the continuous duty zone on a torque curve mean?
The continuous duty zone of the torque-speed curve represents the torque and speed the motor can produce indefinitely without overheating or damage to the motor or drive. Here, the application’s RMS torque is used to determine the motor’s suitability.
What makes a motor have a maximum torque?
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. Because maximum torque is required for only a short amount of time, it can fall outside of the motor’s continuous operating zone, but must fall within the intermittent duty zone.
When to use torque speed curve to select a servo motor?
A servo motor’s torque-speed curve includes two operating zones: continuous duty and intermittent duty. To choose a motor that can meet the application requirements, it’s important to ensure the application runs within the continuous duty zone during normal operation and does not exceed the intermittent duty zone when peak torque is required.
