Said yesterday that the classification step progress motor system, the role of the stepping motor system let people yearning. Alone today for everyone to get a project about structure and function of the step motor stepper motor can be applied to ac motor or dc motor, because of the early high current control can only be done through SCR dc, so before stepping motor is mainly motor, with the transistor can control large current and high frequency switch large current, ac stepping motor is widely used. Early step motor is mainly used to step into the amplifier, now this kind of motor used in step amplification or variable frequency control, this means that a similar stepper motor can be applied to the stepping system, variable frequency drive. Some companies using closed loop control on stepper system instead of using stepper motor, such a connection to a high speed controller of ac motor can also be used as a simple a devoted into the motor in the automatic control system, the output to a certain accuracy to follow the change of the input and change of system known as the servo system, also known as the stepping system. Step system of nc machine tool, for example, is refers to the position and speed of the moving parts in machine tool as automatic control system to control the quantity, also known as the servo system. The stepping system driven by stepping driving devices and components (Or components of stepper motor)Composition, high performance stepping system and detection devices, feedback on the actual state of the output. Stepper system function is to accept instructions from the superior control signals, drivers follow instruction pulse movement of the object, and make sure the action is rapid and accurate, which requires the high quality of speed and position step by step. Above refers to the main feed stepper control, in addition to the main movement of step control, but control requirements higher than the former. The precision of stepping motor control system and speed and other technical indicators tend to mainly depends on the stepping system. 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.
