Stepping motor manufacturers detailed speed regulation principle
Stepper motors are mainly based on a certain power supply law, and the corresponding windings respond to the electrical signals. The motor will run in a certain direction, and each time the electrical signal is changed, the motor will run one step. Operation, as long as the frequency of the electrical signal is changed, different operating speeds will be obtained.
1. When using a stepper motor to regulate the speed, as long as the frequency of the output pulse of the controller is changed, the speed regulation of the stepper motor can be realized. Some manufacturers have also introduced stepping drivers with integrated pulse generators. Users only need to input analog electrical signals or adjust the speed of stepper motors through potentiometers, such as the products of British stepping motor manufacturer Dongguan Bangtuo Transportation Control.
2. A stepping motor is an open-loop control element that converts electrical pulse signals into angular or linear displacement. Under non-overload conditions, the speed and stop position of the motor only depend on the frequency and number of pulse signals, and are not affected by the load change. When the stepper driver receives a pulse signal, it drives the stepper motor according to Rotate a fixed angle in the set direction, and its rotation runs step by step with a fixed angle.
3. A stepper motor is an induction motor. Its working principle is to use electronic circuits to change the DC power into a time-sharing power supply. The multi-phase sequential control current is used to power the stepper motor. When working, the driver is a time-phase power supply for stepper motors, a multi-phase timing controller.
