■ 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-speed operation
The motor is optimized for high rotational speed and is designed to maintain stable operation at elevated speeds. This makes it suitable for applications where high rotary speed is essential for productivity and overall machine throughput.
2. Rapid acceleration and deceleration
Low rotor inertia and high torque response enable the motor to reach the target speed quickly and decelerate rapidly when required. This minimizes unnecessary waiting time between process steps and helps improve overall equipment cycle time.
3. Fast servo response
The direct-drive structure eliminates mechanical transmission components between the motor and load, allowing the motor to respond directly to speed, position, and torque commands. This provides a more agile motion system with improved dynamic performance.
4. Smooth high-speed rotation
The optimized electromagnetic design helps reduce torque fluctuation and maintain stable rotational motion at high speed. This supports smoother machine operation and helps limit vibration and speed variation during high-speed processes.
5. Reduced transmission losses
Without gears, belts, or other intermediate transmission components, the direct-drive system avoids mechanical losses associated with conventional transmission mechanisms. The simplified power path improves transmission efficiency and reduces mechanical components that may limit high-speed operation.
High-speed rotary motors are optimized for applications requiring rapid rotation, fast acceleration and deceleration, and short machine cycle times. Compared with conventional geared rotary systems, the direct-drive structure eliminates mechanical reduction components that can limit speed and introduce transmission losses, allowing the motor to respond directly to servo commands. Low rotor inertia enables the rotary axis to reach target speed quickly and decelerate rapidly, improving overall machine throughput and reducing non-productive motion time. The multi-pole electromagnetic structure and optimized motor design provide stable torque generation and smooth rotation at high speed, while the encoder enables precise speed and position feedback throughout the operating range. These characteristics make high-speed rotary motors suitable for high-speed indexing, scanning, inspection, winding, pick-and-place, electronic manufacturing, and other short-cycle automation applications.
