Torque Equation and the Relationship with DC Motors

Mar 09, 2017 · Understanding the torque equation and the relationship between speed and torque is an important part of selecting and operating a DC motor.. DC motors are relatively simple machines: when the load on the motor is constant, speed is proportional to supply voltage. And when supply voltage is constant, speed is inversely proportional to the load on the motor.

How to use a torquespeed curve to select a servo motor

Jun 14, 2019 · A servo motor''s torquespeed curve includes two operating zones: continuous duty and intermittent duty. To choose a motor that can meet the appliion requirements, it''s important to ensure the appliion runs within the continuous duty zone during normal operation and does not exceed the intermittent duty zone when peak torque is required.

D.C. Motor Torque/Speed Curve Tutorial:::Understanding

1992,by Hugh D. Young:The quantitative measure of the tendency of a force to cause or change rotational motion is called torque. Torque(also called a moment) is the term we use when we talk about forces that act in a rotational manner. You apply a torque or moment when you turn a dial, flip a lightshwitch, drill a hole or tighten a screw or bolt. As shown in the picture of a ratchet, a torque
