A stepper motor is a common type of motor that has the ability to rotate forward and reverse. Changing wires refers to changing the power connection of a stepper motor in order to change its direction of motion. There are many different methods of changing wires, and one of the common methods of changing wires will be detailed below.
A stepper motor is a special type of motor that can rotate at a set stepping angle. It can be turned forward and reverse by changing the polarity of the power supply or the direction of current flow. A stepper motor usually consists of two or four coils, where each coil is driven by an electric current.
The basic principle of the wire change method is to change the order of current flow through the coils, and change the direction of motion of the stepper motor by activating the coils in a different order. A common method of changing wires in a four-wire stepper motor is described in detail below.
Firstly, it is necessary to understand the order in which the coils of a stepper motor are arranged. Stepper motors usually consist of two adjacent coils, each with a terminal. In a four-wire stepper motor, there are two coils, called coil "A" and coil "B". Each coil has two terminals labelled "A1", "A2" and "B1", "B2". These terminals will be connected to the power supply to activate the motor.
In this method of switching wires, we will use two power wires, labelled "Vcc" and "Gnd" to drive the stepper motor. Stepper motors usually require a controller (such as a driver or microcontroller) to control the power connection.
Step 1: Connect "A1" to "Vcc" and "A2" to "B1". In this case, the power supply line is as follows: "Vcc" - "A1" - "A2" - "B1" - "Gnd". -Gnd".
Step 2: Connect "B2" to "Vcc" and disconnect "A1". At this point, the power supply connection is as follows: "Vcc" - "B2" - "A2" - "B1" - "Gnd". -Gnd".
Step 3: Connect "A2" to "Vcc" and disconnect "B1". At this point, the power supply connection is as follows: "Vcc" - "B2" - "A2" - "Gnd".
Step 4: Disconnect "B2" and reconnect "A2" and "A1". At this point, the power supply lines are as follows: "Vcc" - "A1" - "Gnd".
By connecting the power cable according to the above steps, the forward and reverse rotation of the stepper motor can be realised. Firstly, it is necessary to make sure that the power cord is connected correctly to avoid short circuits and other damages to the motor circuit. It is also necessary to ensure that the power cord can supply enough current to drive the stepper motor.
It is important to note that the wire change method for stepper motors may vary depending on the specific motor model and manufacturer. Therefore, when operating a stepper motor, it is recommended to refer to the motor's technical manual or the manufacturer's instructions to ensure that the correct wire change method is used.
To summarise, the stepper motor wire change method is a method of forward and reverse rotation of the motor by changing the order of current connections to the coils. By connecting the power cables in different ways, the order in which the stepper motor coils are activated can be changed, thus changing the direction of motion of the motor. When performing a stepper motor wire change operation, it is necessary to carefully read the motor's technical manual or the manufacturer's instructions and make sure that the power cables are properly connected and sufficient current is supplied.
