What are two-phase stepping motors and drivers?

A two-phase stepping motor is an open-loop control motor that converts electrical pulse signals into angular displacement or linear displacement. It mainly consists of a stator and a rotor. The stator has two sets of windings. By sequentially energizing different windings, a magnetic field is generated to push the rotor to rotate.

A two-phase stepping motor driver is a device specifically used to control the operation of two-phase stepping motors. It receives pulse signals and direction signals from controllers (such as PLCs, single-chip microcomputers, etc.) and converts these signals into currents and voltages suitable for stepping motors to drive the stepping motors to rotate in a specific direction and at a specific speed.

Drivers usually have the following functions:

1. Pulse distribution: Distribute the input pulse signals to the two-phase windings of the motor to determine the rotation direction and step angle of the motor.
2. Current control: Adjust the current output to the motor windings to control the torque and speed of the motor.
3. Subdivision function: By subdividing one step angle into multiple microsteps, the running accuracy and stability of the motor are improved.
4. Protection functions: including overcurrent protection, overheating protection, undervoltage protection, etc., to ensure the safe operation of the motor and driver.

How are the two-phase stepping motors and drivers of the STD and STM series of the SEFOWOD brand used?

The two-phase stepping motors and drivers of the STD and STM series of the SEFOWOD brand can be used as follows: First, make sure you have received the products in good condition and have read the user manual carefully. For installation: 1. Mount the stepping motor and driver in a suitable location according to the requirements of your application. Ensure that the installation is stable and secure to prevent vibration and displacement during operation. 2. Connect the electrical wiring properly. Connect the power supply to the driver according to the specified voltage range. Connect the control signals (such as pulse and direction signals) from the controller (such as a PLC or microcontroller) to the corresponding terminals of the driver. 3. Connect the motor to the driver. Make sure the wiring is correct and firmly connected to ensure reliable transmission of power and signals. For operation: 1. Set the parameters of the driver. Depending on your specific application requirements, you may need to set parameters such as current, micro-step subdivision, and speed. This can usually be done through the driver's control panel or by using software provided by the manufacturer. 2. Send control signals from the controller. The controller sends pulse and direction signals to the driver to control the rotation direction and speed of the stepping motor. The frequency of the pulse signal determines the speed of the motor, and the direction signal determines the rotation direction. 3. Monitor and adjust. During operation, monitor the performance of the motor and driver. If necessary, adjust the parameters to optimize the operation and meet the requirements of your application. It is important to note that when using these products, follow the safety instructions and guidelines provided by the manufacturer to ensure proper operation and avoid potential hazards.
