Absolute Servo Motor

The motor adopts a low-inertia rotor design and a high-dynamic-response control algorithm, resulting in extremely small electrical and mechanical time constants. The delay from receiving a command to generating rated torque can be controlled within milliseconds, enabling instant start/stop, acceleration/deceleration, and direction reversal. This feature is especially suitable for automated production lines, pick-and-place machines, robots, and other scenarios requiring frequent and rapid positioning, significantly shortening action cycles and improving production efficiency.

Thanks to the high-resolution absolute encoder (up to 23 bits) and optimized sinusoidal magnetic field control technology, the motor maintains pulse-free torque output even at extremely low speeds, with very low speed fluctuation. In addition, the cogging torque between stator and rotor is finely suppressed, eliminating the low-speed jitter common in traditional servo motors. This ensures smooth motion trajectories and excellent surface quality in precision machining, optical inspection, medical imaging equipment, and other applications.

The motor uses high-heat-resistant magnet wire and an enhanced heat dissipation structure, allowing it to output peak torque more than 2.5 times the rated torque for short periods. When encountering sudden load impacts or high-inertia startup, the motor can still drive the load stably without needing to stop or derate. This feature significantly enhances the equipment's impact resistance, making it ideal for applications such as injection molding machines, pressing machinery, lifting equipment, and others that require frequent starts/stops or experience instantaneous heavy loads.

Through high-precision dynamic balancing of the rotor, low-noise ball bearings, and optimized electromagnetic force wave design, noise sources are effectively suppressed from both mechanical and electromagnetic aspects. When the motor operates across its full speed range, the measured radiated noise is far below industry standard limits. Even when used in quiet laboratories or medical ward environments, it does not disturb personnel, meeting the stringent requirements of noise-sensitive locations (e.g., operating rooms, precision testing rooms).

The motor employs a low-copper-loss winding scheme and high-performance, low-iron-loss silicon steel sheets, significantly reducing copper losses and eddy current losses during continuous operation. Combined with an integrated heat-dissipating housing or optional air/liquid cooling structures, heat is quickly conducted away. The measured temperature rise is significantly lower than that of同类 products. This not only reduces the impact of thermal deformation on encoder position accuracy but also extends the service life of bearings and insulation materials, making it particularly suitable for equipment that runs continuously for long periods or in confined spaces.

Through a compact electromagnetic topology and integrated absolute encoder design, the motor's axial length and mounting diameter are reduced by approximately 20% to 30% compared to traditional servo motors, while delivering the same torque output. Its extremely low weight and volume allow it to be easily embedded in space-constrained mobile platforms such as robotic joints, drone power modules, and portable medical devices, while maintaining high torque output – providing key component assurance for the miniaturization and lightweight design of complete machines.
