The resistance value of a stepper motor has a significant impact on its performance, including current, heat generation, torque, and speed. Therefore, selecting the appropriate resistance value is crucial. Here are some principles to consider when selecting resistors for stepper motors:   1. Determine the Appropriate Resistance Value Based on Motor Voltage and Current   The resistance value of a stepper motor can be calculated using the following formula:   R = U / I   Where: R: Resistance value (unit: ohm) U: Motor voltage (unit: volt) I: Motor current (unit: ampere) When selecting the resistance value, ensure that the motor current does not exceed its rated current. Otherwise, the motor may overheat and damage.   2. Determine the Appropriate Resistance Value Based on Motor Torque and Speed Requirements   The relationship between motor torque and speed with the resistance value is as follows:   Torque is directly proportional to current and ...

Stepper motor inductance is a crucial parameter that influences motor performance. Its primary functions are as follows:   1. Energy Storage   When voltage is applied to the motor, the inductance stores energy, generating a magnetic field. Upon voltage removal, the inductance releases energy, sustaining the magnetic field's decay for a period.   Limiting Current Change Rate   Inductance impedes abrupt current changes. According to Lenz's law, when current changes, the inductance generates a counter-electromotive force (CEMF) that opposes the current change. This is essential for stepper motor control as the motor requires rapid current direction changes to achieve stepping motion.   Impacting Motor Response Speed   Inductance reduces the motor's response speed to control signals. This is because the inductance takes time to store and release energy. For high-speed applications, choose motors with lower inductance to enhance response speed. ... Continue reading →
