In the process of operation, the company always insists on innovation and quality first, providing customers with products with high cost performance. 1. What is a stepping motor? Stepping motor is an actuator that converts electrical pulse into angular displacement. When the stepping driver receives a pulse signal, it drives the stepping motor to rotate a fixed angle (The step angle). You can control the amount of angular displacement by controlling the number of pulses, so as to achieve the purpose of accurate positioning; At the same time, you can control the speed and acceleration of the motor by controlling the pulse frequency, thus achieving the purpose of speed regulation. 2. Classification of stepping motors: stepping motors are divided into three types: permanent magnet (PM), Reaction formula (VR)And hybrid (HB) : Permanent magnet stepping is generally two-phase, with small torque and volume, and the stepping angle is generally 7. 5 degrees, or 15 degrees; Reactive stepping is generally three-phase, which can realize large torque output, and the stepping angle is generally 1. 5 degrees, but the noise and vibration are very large. Hybrid Stepping refers to the combination of the advantages of permanent magnet and reactive type. It is divided into two phases, five phases and three phases: the two-phase stepping angle is generally 1. 8 degrees, this stepping motor is the most widely used. 3. How to determine the DC power supply of the stepper motor driver: 3. 1. Determination of voltage the power supply voltage of hybrid stepping motor drivers is generally a wide range ( For example, the power supply voltage of 2M530 is 24 ~ 45VDC) The power supply voltage is usually selected according to the working speed and response requirements of the motor. If the working speed of the motor is high or the response requirement is fast, the voltage value is also high, but note that the ripple of the power supply voltage cannot exceed the maximum input voltage of the driver, otherwise the driver may be damaged. B. The determination of current the power supply current is generally determined according to the output phase current I of the driver. If a linear power supply is used, the power supply current can generally be 1 of I. 1 ~ 1. 3 times; If switching power supply is used, the power supply current can generally be read by I's ruite stepping motor: What are the classification and uses of stepping motor drivers?
