In this case, 8 steps are taken in the forward direction, followed by 2 steps in the reverse direction, repeating this cycle every 1 second.</p> <p>The load angle is seen to increase and decrease as expected, until the 4th step of the second cycle. At that point, the spring's torque exceeds the capability of the stepper motor, causing it to "snap back" suddenly to a negative angle, below the initial starting point! The phase currents of the motor reflect the sequencing of the drive switches in forward and reverse direction.</p> About text formats Tags stepper motor Select a tag from the list or create your own.Drag to re-order taxonomy terms.

Copy of Torque-Speed evaluation of Stepper motor (ramped torque) - on Mon, 07/24/2023 - 11:02 User-1689277080Designer247507 × User-1689277080 Member for 1 year 5 months 5 designs 1 groups Welcome to the community!! https://explore.partquest.com/node/601824 <iframe allowfullscreen="true" referrerpolicy="origin-when-cross-origin" frameborder="0" width="100%" height="720" scrolling="no" src="https://explore.partquest.com/node/601824"></iframe> Title Description <p>Torque-Speed characteristics of a stepper motor are evaluated using an adjustable friction brake, maintaiining D_VISCOUS at minimum possible or cero, adjusting TORQ_FRIC_KINETIC to apply mechanical load to the motor. TORQ-FRIC-STATIC must always be greater than the kinetic one to avoid simulation problems.</p> <p>Step frequency must be adjusted too, starting with low frequency the mechanical friction must be increased until the motor loses steps, thus obtaining the first T-n point.</p> <p>The same procedure must be done for greater pulse frequescies.</p> <p>The 2 H-bridges are supossed to simulate a simple driver like the L298N (based on an example available on the page)</p> <p>Motor data is based on NanotecST4118S1404-B.</p> About text formats Tags stepper motorTorqueSpeedDynamometer Select a tag from the list or create your own.Drag to re-order taxonomy terms.
