Hello, for asynchronous Motor there is no torque and voltage constant. Some data you find Configuration Manual. http://support.automation.siemens.com/WW/view/en/46484744 Starter has motordata of standart siemens motors.

Q1. whichwinding resistancedo I select,stator or rotor resistance? 1.winding resistance [ohm], winding resistance = (in 1PH8 asynchrous motor case) Q2. How to calculate damping coefficient, Torque Constant, and Voltage Constantin detail? 1. damping coefficient [Nm/rad/sec] 2. Torque constant [Nm/A] Torque constant = rated Torque / rated current ? 3. Voltage Constant [V/1000rpm] Voltage constant = rated voltage / 1000rpm ? Q3. aren't there torque constant, voltage constant, and damping coefficient in induction motor(asynchronous motor)? and Why doesn't it exist in? It supposed tocalcurat torque constantIn servomotor case. Approximately Rated torque / Rated current AttachmentC:\Users\sel05113\Desktop\Projektierungsdaten_1FK7022_76[1].pdf (294 Downloads) |
