Two-phase open-loop stepper motor with gearbox

By controlling the number of input pulses, the output angle can be accurately to achieve the positioning function.

By controlling the frequency of the input pulse, the output angle speed can be accurately controlled due to the purpose of speed regulation can be achieved.

The motor mainly works at 1000rpm and below.

Mainly used in occasions where low-speed mechanisms require accurate positioning and speed regulation.

Two phase open-loop stepper motor (standard type) is an actuator that converts electrical pulse signals into angular or linear displacement. Its working principle is that when the stepper driver receives a pulse signal, it drives the stepper motor to rotate a fixed angle (called "step angle") in the set direction. The following is a detailed analysis of the two-phase open-loop stepper motor (standard type):

1、 Basic characteristics

Phase number: Two phases, which means there are two independent magnetic field phases inside the motor, and the rotation of the motor is achieved by controlling the currents of these two phases.

Open loop control: Unlike closed-loop control, open-loop control does not rely on feedback signals to adjust the output, but directly controls the motion of the motor based on the input pulse signal. Therefore, open-loop control has the advantages of simple structure and low cost, but may be slightly inferior to closed-loop control in terms of accuracy and stability.

High precision positioning: Although open-loop control is adopted, the two-phase stepper motor can still achieve high positioning accuracy, thanks to its precise step angle and good control performance.

Low speed high torque: Stepper motors can output a large torque at low speeds, which makes them widely used in situations that require high torque drive.

2、 Main parameters

Step angle: Step angle is an important parameter of a stepper motor, which represents the angle of rotation of the motor for each pulse signal received. The step angle of a two-phase stepper motor is usually 1.8 ° or smaller, depending on the design and manufacturing of the motor.

Rated voltage and current: These parameters determine the working conditions and performance of the motor. Rated voltage usually refers to the voltage value required for a motor to operate normally, while rated current refers to the maximum current value allowed for the motor to operate continuously at rated voltage.

Holding torque: Holding torque refers to the maximum torque that a motor can withstand external loads without rotating when not powered. The magnitude of the holding torque directly affects the load capacity and stability of the motor.

3、 Application Fields

Two phase open-loop stepper motors (standard type) are widely used in various automation equipment and mechanical systems, such as CNC machine tools, textile machinery, packaging machinery, printing machinery, automation equipment, robots, etc. They play an important role in these devices, achieving precise position and motion control.
