Coreless Motor Assembly

The Jiecang coreless motor assembly is available in three core diameters: Φ8mm Φ10mm and Φ12mm. The motor itself offers extremely high rotational speed (up to 38 000 rpm no-load) and a rated torque range from 1.0 mNm to 3.0 mNm. It is paired with a multi-stage planetary gearbox that provides a wide selection of reduction ratios (e.g. from 4 to 807) increasing the continuous output torque to a maximum of 0.35 Nm. The assembly module features a broad operating temperature range of -40°C to 100°C*and supports receiving commands and providing feedback via buses such as EtherCAT and CAN. High Power Density & Fast Response:：The rotor of the coreless motor has extremely low inertia which combined with its high speed gives the module millisecond-level dynamic responsecapabilities enabling rapid start and stop. Precise Motion & Control:：The gearbox has minimal no-load backlash (as low as ≤1.2°) and when combined with closed-loop control it enables precise position and speed adjustment making it suitable for force control grasping and other delicate operations. High Integration & Reliability：The motor and gearbox are highly integrated resulting in a compact structure. Gears are manufactured to high precision grades (some up to grade 6) ensuring smooth operation and long service life under prolonged high-load conditions. Design Flexibility:：The series-based modular design allows for flexible selection and pairing based on torque speed and size requirements enabling quick adaptation to application scenarios with stringent demands on space and performance such as robotic dexterous hands and joint modules.
