Core features
High precision control: Utilizing advanced control algorithms and 23-bit encoders, it achieves positioning accuracy of sub-arc-second level. For example, the rotation stage of a CNC machine can reach a precision of 0.001°, eliminating transmission gaps and enhancing the surface quality and repeatability of the processed parts.
Fast response: The electronic commutation technology and low inertia design give the motor an acceleration time of less than 50ms, suitable for high-frequency start-stop scenarios (such as lithium battery slicing and packaging machinery), increasing production cycle efficiency by more than 20%.
High reliability: The rare earth permanent magnets and optimized magnetic circuit design support a wide speed regulation range and high dynamic response. Integrated with thermal resistors and over-temperature protection functions, it is suitable for dusty, humid, and high-temperature conditions (such as metallurgical and chemical equipment).
Strong environmental adaptability: IP65 protection, wide temperature range, and anti-pollution design (such as shaft sealing ring + dust cover), modular structure supports rapid maintenance (such as stator winding replacement), reducing downtime costs.
Intelligent integration: Supports bus interface to collect multi-dimensional data such as motor temperature, vibration, and current, and combines with the Yaskawa IndraWorks software to achieve predictive maintenance (such as fault warning, parameter optimization).
