■ Inner Structure
■ Product Principle
A rotary motor consists of a rotor and stator. The rotor is the load itself or directly connected to the load, and is equipped with permanent magnets. The stator is fixed to the base and contains multiple coils. Based on the electromagnetic principle, energizing the coils generates a rotating magnetic field, which directly drives the permanent magnet rotor to rotate. The rotor speed is determined by the frequency of the applied current, while its position is controlled by the phase of the current.
■ Product Advantages
1. Integrated Brake System
An integrated electromagnetic brake is built into the motor. The brake releases when power is applied and engages when power is removed, providing reliable position holding and safety protection without the need for an external brake. This saves installation space and reduces system cost.
2. Zero-backlash Safety Holding
The brake system provides zero-backlash holding with sufficient braking torque to reliably hold the load during power loss or emergency stops. This helps prevent unintended movement or drift on vertical axes, enhancing the safety of both equipment and personnel.
3. Full Direct-drive Performance
The brake unit is fully integrated with the motor while retaining the core advantages of DDR direct-drive technology, including zero backlash, high rigidity, rapid response, and high precision. The integrated brake is designed to minimize its impact on the motor's dynamic performance.
4. Designed for Vertical and Safety-critical Applications
The motor is specifically designed for applications requiring reliable holding and braking when power is removed, including vertical lifting axes, direct-drive Z-axis mechanisms, robotic joints, and CNC rotary table indexing. It provides a practical solution for automated equipment where secure position holding is essential.
The brake series features a self-locking function, providing enhanced safety and extended functionality compared with standard rotary motors. An integrated electromagnetic brake releases when power is applied and engages when power is removed, providing reliable position holding and safety protection. The brake system provides zero-backlash holding with sufficient braking torque to securely retain the load during power loss or emergency stops, helping prevent unintended movement or drift. The compact design integrates the brake unit directly into the motor, eliminating the need for an additional external brake and saving valuable installation space. The series is widely used in applications requiring reliable power-off holding and safety braking, including vertical lifting axes, direct-drive Z-axis mechanisms, robotic joints, CNC rotary table indexing, and automated assembly lines.
