Stepper motor applications _ two phase four-wire stepping motor specifications
among them, asking people in the use of stepper motor, don't put metal debris and dust ( Characteristics: solid particles) Into the motor drives the plate, the key reason is that the motor drive board is not seal structure, its structure is an open state, once the metal debris and dust fall into to the structural part, is easy to attach on the driver board in the related parts, (thus easy to cause a short circuit Current without even directly with electrical appliances, power poles) The problem. Stepper motor driver stepper planetary gear motor can't directly to the power frequency ac or dc power supply work, and must use a dedicated driver, as shown, it is controlled by pulse generating unit, power drive unit, protection unit, etc. Figure midpoint line surrounded by two units can be done with microcomputer control.
stepper motor drive can be controlled by controlling the pulse number of angular displacement, so as to achieve the purpose of accurate positioning; As well as by controlling the pulse frequency to control motor rotation speed and acceleration, so as to achieve the purpose of speed regulation and positioning. Once stepping planetary gear motor short circuit occurs, normal operation of the will, nature will not function properly, you can't normal use.
so, in order to guarantee the stability of the stepping motor to ( Explanation: solid stability; There is no change) Operation, reliable function, normal use for a long time, requires that everyone in the use of the motor, don't put metal debris and dust ( Characteristics: solid particles) Fall into the motor driver board, to protect the circuit on the driver board through, to do a good job in security in terms of operation and function of the motor.
