Two phase closed-loop stepper motor (standard type) is a type of stepper motor that combines closed-loop control technology. It adds a position feedback device (such as an encoder) to the traditional stepper motor, thereby achieving higher precision position control. The following is a detailed analysis of the two-phase closed-loop stepper motor (standard type):
1、 Product Features
Closed loop control: Unlike traditional open-loop stepper motors, two-phase closed-loop stepper motors monitor the actual position of the motor in real time through a built-in high-precision encoder, and compare it with control instructions to achieve precise control of the motor position. This control method can greatly reduce position errors caused by factors such as step loss and oscillation, and improve the stability and reliability of the system.
High precision: Due to the use of closed-loop control technology, the two-phase closed-loop stepper motor can achieve higher positioning accuracy and repeat positioning accuracy. This is particularly important for application scenarios that require precise position control, such as automation equipment, robots, medical equipment, and other fields.
High response speed: The closed-loop control system can respond to control instructions more quickly, enabling the motor to reach the target position in a short period of time. This helps to improve production efficiency and automation level.
Multiple models to choose from: There are various sizes, powers, and performance of two-phase closed-loop stepper motors available on the market for users to choose from, to meet the needs of different application scenarios.
2、 Working principle
The working principle of a two-phase closed-loop stepper motor is based on the basic working principle of a stepper motor, which drives the motor to rotate a certain angle according to the input pulse signal. Compared with traditional open-loop stepper motors, the two-phase closed-loop stepper motor adds a position feedback loop. When the motor receives the control pulse signal, the driver will adjust the driving current and phase of the motor in real time based on the feedback signal from the encoder to ensure that the motor can rotate accurately and stably to the target position.
3、 Application Fields
Two phase closed-loop stepper motors (standard type) are widely used in applications that require high-precision position control, high response speed, and reliable operation, such as:
Automation equipment: In automated production lines, two-phase closed-loop stepper motors can be used to accurately control the position and speed of moving parts such as robotic arms and conveyor belts, improving production efficiency and product quality.
Robots: In the field of robotics, the high-precision and fast response characteristics of two-phase closed-loop stepper motors make them one of the preferred motors for robot joint drive. By precisely controlling the various joints of the robot, complex movements and precise positioning can be achieved.
Medical equipment: In medical devices such as surgical robots, rehabilitation equipment, etc., the high-precision and low-noise characteristics of the two-phase closed-loop stepper motor can meet the strict requirements for accuracy and comfort.
Optoelectronic equipment: In optoelectronic devices such as laser equipment and optical instruments, high-precision control of two-phase closed-loop stepper motors helps achieve precise optical path adjustment and positioning.
