NEMA 14 Stepper Motor Wiring Diagram
KNOWLEDGE BASE --- Heating principle of stepper motor driver
All types of motors that are usually used by users have iron cores and winding coils inside. Windings have resistance, energization will produce loss, the loss is proportional to the resistance and the square of the current, which is what we often call copper loss. If the current is not a standard DC or sine wave, it will also produce harmonic loss. What's more, iron core has hysteresis vortex effect and also produces loss in the alternating magnetic field and its magnitude is related to the material, current, frequency as well as voltage, which is called iron loss. Both copper loss and iron loss will show up in the form of heat, which affects the motor efficiency. Stepper motors generally are used for positioning accuracy and torque output, with relatively low efficiency, relatively large currents and high harmonic components. The frequency of current alternation also changes with the speed accordingly. Therefore, stepper motors generally have heat generation and the situation is more vortex than normal AC motors.
