■ 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、High response and high rigidity
Equipped with low-inertia rotating components and a reinforced drive system, it fully utilizes servo control performance to enhance machine dynamics. The I-PD control loop enables shorter settling time and provides high rigidity, allowing the system to withstand sudden external forces.
2、High-precision speed control
The rotary motor eliminates the need for a reducer and backlash. With a high number of motor poles, it provides minimal torque fluctuation, achieving excellent speed stability and precise velocity control.
3、Space saving
Rotary motors eliminate the need for reducers, resulting in a more compact drive system and reduced space requirements.
4、Maintenance-free operation
Rotary motors eliminate intermediate components such as reducers and belts, requiring no disassembly or regular maintenance. By directly connecting to the load, they provide a more stable power transmission system with zero backlash, high-speed, and high-precision motion performance.
5、Flexible adjustment
Without a gear mechanism, parameters can be easily adjusted through software control. Zero backlash and zero elastic deformation errors deliver a more responsive and agile system performance.
In the customized fixed stator series, the stator and base plate serve as the fixed end, providing a highly stable and rigid reference platform for workpieces that do not require rotation but need precise positioning and installation. Leveraging the inherent zero-backlash advantages of direct-drive technology and its elimination of intermediate transmission components, the system delivers significantly enhanced rigidity while removing the backlash and coupling errors associated with conventional transmission methods. The integrated high-rigidity design of the base and stator provides a solid and stable mounting platform for precision workpieces, effectively suppressing external vibration and helping maintain positioning accuracy. The series also supports application-specific customization, allowing mounting interfaces and installation layouts to be tailored to different workpieces and space requirements.
