High-speed rail station ticket-checking gates

In December 2019, Jiayu Mechanical & Electrical’s EPS-series servo electric control system—comprising both drive units and motors—was integrated into a partner’s high-speed rail ticket-checking turnstile. Over 100 channels were successfully deployed at Shenzhen North Station. Thanks to its fast gate-opening and closing, precise positioning, and low operating noise, the system effectively supported peak passenger volumes during the Spring Festival travel rush, earning high praise from the partner.

A Paragon of High-Performance Permanent-Magnet DC Servo Motors

Permanent-magnet DC servo motors are devices that convert electrical energy into mechanical energy and are widely used in industrial automation, robotics, aerospace, and other fields. Owing to their unique structure and outstanding performance, they have become the benchmark for high-performance motors. I. Structural Composition A permanent-magnet DC servo motor consists primarily of a stator, rotor, permanent magnets, armature windings, and a commutator. The stator is the stationary part of the motor, typically constructed by laminating silicon steel sheets and housing the armature windings. The rotor is the rotating component, usually made of magnetically permeable material and fitted with permanent magnets at both ends. The armature windings serve as the motor’s power input and are connected to the external circuit via the commutator. The commutator is a critical component that switches the direction of current in the armature windings, thereby ensuring continuous rotation of the motor. II. Operating Principle The operating principle of a permanent-magnet DC servo motor is based on Faraday’s law of electromagnetic induction and the Lorentz force law. When current flows through the motor’s coils, a magnetic field is generated within the motor. This magnetic field interacts with the magnetic field produced by the permanent magnets, generating a torque that causes the rotor to rotate. By adjusting the direction and magnitude of the current, the rotational speed and direction of the rotor can be precisely controlled. In addition, an encoder is mounted on the motor’s shaft and rotates in synchrony with the rotor to detect its position.

Subway turnstile driver: the core power source for subway access

The metro turnstile actuator is a critical component of the metro turnstile system, responsible for driving the opening and closing of the turnstile gates and thereby ensuring the safe and efficient passage of metro passengers. I. Types of Metro Turnstile Actuators Metro turnstile actuators are mainly categorized into two types: electric actuators and hydraulic actuators. Electric actuators are widely used in metro turnstile systems due to their simple structure, ease of maintenance, and smooth operation. Hydraulic actuators, on the other hand, are favored in certain metro turnstile systems with special requirements because of their high driving force and rapid response. II. Operating Principle of Metro Turnstile Actuators The operating principle of a metro turnstile actuator is based on the drive mechanism of an electric motor or a hydraulic cylinder. Upon receiving a command from the control system, the actuator is activated, causing the motor or hydraulic cylinder to operate and thereby driving the turnstile gate to open or close. In electric actuators, the rotation of the motor drives a transmission mechanism, which in turn moves the turnstile gate; in hydraulic actuators, the extension and retraction of the hydraulic cylinder achieves the opening and closing of the gate. III. Performance Characteristics of Metro Turnstile Actuators High Efficiency and Stability: Metro turnstile actuators employ advanced drive technologies and materials to ensure the efficiency and stability of gate opening and closing, thus facilitating the rapid passage of metro passengers.

Electric Forklift Controller: The Intelligent “Brain” of the Forklift

2025/01/15

Core Drive Component of DC Servo Motor Electric Forklift System

DC servo motors play a critical role in the drive system of autonomous forklifts, enabling precise control over the vehicle’s speed and direction. For instance, when the forklift needs to move forward, reverse, or turn, the DC servo motor can swiftly and accurately adjust its speed and torque in response to commands from the control system. Compared with conventional motors, DC servo motors offer faster response times, allowing the forklift to accelerate rapidly from a standstill to the desired speed within a short period—a capability that is essential for autonomous forklifts to navigate flexibly among warehouse racks in complex environments.

Composition and Principle of Permanent Magnet DC Servo Motors

Permanent-magnet DC servo motors are high-performance electric motors widely used in various automatic control systems. I. Composition A permanent-magnet DC servo motor primarily consists of the motor body and sensing components. The motor body comprises three main parts: the housing, the stator poles, and the rotor. The stator poles are made of permanent magnets, eliminating the need for excitation windings and excitation current, thereby reducing both size and losses. The rotor is responsible for generating induced electromotive force and electromagnetic torque. Sensing components typically include high-precision tachogenerators, resolver encoders, and pulse encoders, which are coaxially mounted at the motor’s rear end to provide feedback on the motor’s operating condition. II. Characteristics Small size and light weight: Due to the use of permanent-magnet excitation, no excitation power is required, allowing permanent-magnet DC servo motors to achieve a smaller footprint and lighter weight at the same output power. Rigid mechanical characteristics: The motor speed decreases only slightly with increasing load, maintaining nearly constant speed; this enables permanent-magnet DC servo motors to deliver stable performance even under conditions of large load variations. Maintenance requirements: The brushes and commutator are prone to wear and require regular inspection and replacement, increasing maintenance costs. Limited speed: Sparking occurs during commutation, which restricts the motor’s maximum speed. III. Operating Principle
