Stepper motor drive (伺服驱动器)Also known as the 'stepping controller', 'step amplifier', a controller is used to control stepping motor, its action is similar to the frequency converter to ordinary ac motor, belonging to step into the system, as part of the main application in high precision positioning system. Typically by position, speed, and three ways to control stepping motor torque, high precision positioning of transmission system, is currently the transmission technology of high-end products. 1, if the ac power, and drives the dc bus (Such as transformer)No isolation between, don't will not isolated port or isolation of dc bus signal in the land of the earth, which can cause damage to the equipment and personnel damage. Because of public ac voltage is not of the earth, and the dc bus may be very high voltage between the earth. 2, in most of the stepping system, all the public and the earth in the signal terminal is meet together. Many kinds of way to connect the earth produces ground loops can easily affected by noise and produce flow in different reference points. 3, step progress motor in order to maintain a constant reference voltage command, stepper motor drive signal ground to received signals from the controller. It will also receive the external power supply, which will harm the work of the controller and driver (Such as: the encoder 5 v power supply)。 4, shield grounding is relatively difficult, there are several ways. Correct shielding meet is located in the reference potential point is inside of the circuit. This point depends on whether the noise source and receiving ground at the same time, or empty. To ensure that current in the same point grounding makes the shield will not through the shield. with the large-scale application of the stepping system, stepping motor drive using, debugging stepper motor drives, stepper motor drives maintenance are stepper motor drives in today's important technologies, more and more industrial technology service provider for step motor drive technology in-depth research. 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.
