Static torque characteristics for stepper motor rotor static state (Balance)Features, this feature has nothing to do with time, also known as the point of a static static torque characteristics or stiffness characteristics, is stepping motor stator dc excitation condition, the changes of load torque and rotor displacement Angle. (1)Torque table: the stepper motor is fixed. Readings of torque table, as shown in the figure and Angle measuring instrument readings, according to draw from the Angle of Angle and torque characteristic curve, as shown. If you don't measure Angle, can only measure the maximum static torque TM. (2)Pulley weight method, as shown, with pulleys and weight instead of the figure torque table. In turn, change the weight of the weight W, using potentiometer or encoder measuring Angle, also can get the same as the torque table torque curve. (3)Stress meter and encoder, the aforementioned two methods need artificial load torque values, measurement time, and cannot automatic torque curves are obtained. Relative, as is shown above, strain gauge torque meter and optical shaft encoder directly connected to the stepper motor, and utilization of torque meter, encoder and X-rayY recorder, to continuous measuring static torque characteristics. the main products: stepper motor, brushless motor, servo motor, stepping motor drive, brake motor, linear motor and other kinds of models of the stepper motor, welcome to inquire.
