The main features of 1, general stepping motor for the step Angle of 3 - precision5%, and do not accumulate. 2, stepper motor appearance allows maximum temperature. Stepper motor temperature too high can make motor demagnetization of magnetic materials, first step motor (Figure 8)Stepper motor (Figure 8)Leading to torque decline and even out of step, so the motor appearance allows the highest temperature should depend on different points of demagnetization magnetic material; Demagnetization of magnetic materials, in general, some are above 130 degrees Celsius, some even as high as 200 degrees Celsius above, so the temperature in Celsius 80 - step motor appearance90 degree completely normal. 3, stepper motor torque vary with the increase of rotational speed will be reduced. When stepping motor rotation, the motor of each phase winding inductance will form a reverse electromotive force; The higher the frequency, the greater the back emf. Under the function of it, the motor with frequency (Or speed)The phase current decreases, which leads to torque decline. 4, the step motor at low speed can operate properly, but above a certain speed won't be able to start, accompanied by squeaking noise. Stepper motor has a technical parameters: no-load start frequency, the stepper motor under no-load condition can normal boot pulse frequency, if the pulse frequency is higher than the value, the motor does not start properly, may be lost or blocked. In the load cases, start frequency should be lower. If you want to make the motor to achieve high-speed rotation, the pulse frequency should be to accelerate the process, namely the start frequency is low, and then in a certain high frequency acceleration to want (Motor speed from low speed to high speed)。 Stepper motor with its remarkable characteristics, in the era of digital manufacture plays a significant purpose. With the development of digital technology and stepper motor itself, improve technology, stepping motor will be applied in more fields. Main features 1, the stepper motor must add driver can run, drive signal must be a pulse signal, step motor (Figure 9)Stepper motor (Figure 9)No pulse, stepper motor static, if add the appropriate pulse signal, will be at a certain Angle,Called the step Angle)The rotation. Rotation speed and pulse frequency is proportional to the. 2, three-phase stepper motor step Angle of 7. 5 degrees, a circle of 360 degrees, need 48 pulse. 3, step motor has the superior characteristic of instantaneous start and stop rapidly. 4, changing the order of the pulse, easy to change the direction of rotation. Therefore, printer, plotter, robots and other equipment are driven by stepping motor core. 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.
