■ 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 torque output
The larger motor diameter provides increased electromagnetic torque capacity, making the motor suitable for rotary applications requiring higher driving torque and greater load capacity. Direct-drive transmission allows the available torque to be transferred directly to the load without the efficiency losses of a reduction mechanism.
2. High rigidity and stable motion
The direct-drive structure reduces mechanical compliance and eliminates backlash associated with conventional gear transmission systems. Combined with a rigid mechanical structure, it provides stable rotary motion even when the system is subjected to dynamic loads and external disturbances.
3. Fast acceleration and deceleration
High torque output together with optimized rotor inertia enables rapid acceleration and deceleration of the rotary load. This improves machine responsiveness and helps shorten indexing, positioning, and processing cycles.
4. High-precision torque transmission
Without gears, belts, or other intermediate transmission components, the motor transfers torque directly to the load with minimal mechanical transmission error. This provides more accurate torque control and improves the consistency of rotary positioning.
5. Simplified mechanical structure
The direct-drive configuration eliminates the need for additional reduction mechanisms and their associated couplings, shafts, and mounting components. This reduces the number of mechanical parts, simplifies equipment design, and can improve overall system reliability.
Within 300mm rotary motors are designed for applications requiring higher torque, greater load capability, and stable rotary performance while maintaining the advantages of direct drive. The larger motor diameter provides a higher torque output and allows the rotary mechanism to handle heavier loads without relying on an external reduction mechanism. The motor directly connects to the load, eliminating gearbox backlash and reducing mechanical transmission components, which improves torque transmission accuracy and dynamic response. A rigid mechanical structure combined with high-resolution feedback supports stable positioning under demanding operating conditions, while the multi-pole design helps achieve smooth and low-ripple torque output. These characteristics make the series suitable for larger rotary tables, machine tools, industrial positioning systems, automation equipment, and other applications requiring high torque and precise rotary control.
