![]() With its gear ratio freer than before, FLEXWAVE boasts a significantly seamless control of 50 – 120. Furthermore, the externally toothed gear, which is made of a highly ductile, thin steel-type material, is deformed with the bearing to mesh properly with the internally toothed gear, making FLEXWAVE’s backlash low. FLEXWAVE, whose externally toothed gear is combined with an internally toothed one, has inside an elastic bearing, whose shape changes ellipsoidally. Meeting this requirement means to address the issue of backlash, which is created between gears. Additionally, to realize nursing care personnel’s movements accurately, the actuator must be controlled extremely accurately. This kind of motors often need 3D calculation software, with long and complex. Even the middle-type, which is for the waste, is only 20mm thick, while the diameter is 90mm. Axial Flux Motor is the application for Electric Motors with Axial Flux. This is why power assist suits’ actuators are required to be thin and compact.įLEXWAVE, a reducer that Nidec-Shimpo started supplying in 2015, is thin enough to meet such requests from nursing care fields. However, at medical care fields, where personnel need to be able to walk narrow passages and walk through narrow door spaces, sufficient caution must be taken to keep actuators’ users from being injured. In principle, any drive component’s actuator has to be large and thick as it is required to generate large power. Using a “shape-changing gear structure” to realize seamless control and a thin actuator The range includes wholesale axial flux motor options which utilize the basic functions of a DC motor, where electrical currents are used to create a magnetic. Many models have two axes or so (the waste and the knees). Each model has different places to set an actuator on. The YASA 750 R is an axial-flux electric motor with high torque and power densities. At present, a single power assist suit costs 600,000 to three million yen. Together, they generate a strong force as the person wearing a power assist suit moves, relieving burden from the waste and feet. Each actuator comprises a reducer, a controlling unit, and a motor, a source of driving force. Their market will soon reach 12 billion yen, and some are estimating it to more than quintuple in the next five years.Īctuators to drive joints are essential components for power assist suits. The new technology is used for electric motors in electric vehicles with a high power density and efficiency requirement. It is amid these circumstances that the needs for power assist suits, a tool to support physical functions, are on the rise. Japanese nursing care facilities are already suffering from a serious labor shortage, and easing nursing care personnel’s burden is a social issue. Japan’s elderly population keeps increasing, and is expected to reach 30% of the country’s entire population in 2025. Another product, the axial flat motor (AFM), is a device that Nidec Research and Development Center, Taiwan developed for super-flat actuators, and it has a. ![]() Utilize shape-related merits to a reducer-equipped, light, thin, short, and compact actuator. SOLUTION Develop a flat, high-power-density actuator.
