The Back Emf can be calculated from the properties of the actuator: Back Emf Voltage = B * n * speed , Back Emf Constant = B * n (With B being the magnetic field flux and n being the number of windings) If you compare this with the Force Constant formula: Force = B * I * n , , Force Constant = B * nTo calculate the Torque Constant read the current draw at a given torque on the Typical Performance Characteristics graph. Now divide the torque by the current. To calculate the Motor Voltage Constant read the no-load speed (rpm) and convert it to radians per second. Take the Rated Voltage of the motor and divide it by the speed. 17th century clothing patterns In the hallway faint pink rose-patterned wallpaper peeled in places.
