Unlike conventional motors, the rotor does not have an iron core, which makes it lighter and more responsive at high speeds. In addition, the absence of an iron core reduces cogging (the sensation of catching during rotation), resulting in stable rotation characteristics."},{"description_title":"Features of coreless motors","description_text":"\uff65Compact and lightweight\r\nSince there is no iron core, the weight is light.\r\n\r\n\uff65Excellent controllability\r\nSince the rotor is lightweight and has low inertia, the mechanical time constant of the rotor can be reduced. As a result, quick start and stop are possible, enabling excellent responsiveness.\r\n\r\n\uff65Smooth mobility (cogging-free)\r\nGeneral motors have an iron core. This iron core is attracted to the permanent magnet, causing torque ripple during motor drive states and cogging torque in non-energized states, which are types of torque fluctuations.\r\nSuch torque fluctuations can be one of the reasons for the inability to perform targeted operations in electronic devices.\r\nIn contrast, coreless motors have no iron core (core), resulting in virtually no torque pulsations and smooth rotation.\r\n\r\n\uff65High efficiency and energy savings\r\nThe absence of an iron core eliminates iron loss between the magnets, resulting in a high-efficiency motor that can operate at low current consumption.\r\nTherefore, in battery-powered products, it is possible to achieve long battery life.\r\n"},{"description_title":"Why choose our coreless motors?","description_text":"\uff65Winding technology\r\nIn addition to using powerful magnets, the shape of the windings that contribute to the magnets is extremely important in determining the characteristics of a motor.\r\nC.I. TAKIRON has multiple coil winding technologies, and our strength lies in our ability to convert electrical energy into mechanical energy in a space-saving and highly efficient manner.\r\n\r\n\uff65Precious metal brushes and carbon brushes\t\t\t\t\t\t\t\t\t\t\t\r\nC.I. TAKIRON uses many precious metal brushes because they are highly conductive and can operate at low voltages.\r\nCarbon brushes can be used for applications that require relatively large currents, such as motors that are frequently turned on and off.\r\nIn addition, brush motors generate large currents during heavy loads because the commutator and brushes come into contact during rotation.\r\nAs a countermeasure for such large currents, adding capacitors is possible, so please feel free to consult with us regarding operation.\r\n\r\n\uff65Low-voltage startup\r\nOur small motors can start up at low voltages, enabling the operation of small devices using contactless power supply such as NFC in smartphones.\r\nWe also offer models that can be started at a minimum of 1.0V, and we can consider low-voltage characteristics tailored to your needs."}],"term_gallery_image_main":6422,"term_gallery_image_main_alt":"","term_gallery_image_1":3253,"term_gallery_image_1alt":"","term_gallery_image_2":3229,"term_gallery_image_2alt":"","term_gallery_image_3":3238,"term_gallery_image_3alt":"","term_gallery_video_file":4520,"term_gallery_video_youtube":"","term_gallery_video_thumb":3238,"term_gallery_video_thumb_alt":"","term_faqs":[{"faq_question":"difference in life expectancy between coreless motors and brushless motors","faq_answer":"Brushless motors tend to have a longer service life, partly because brushless motors have no brushes."},{"faq_question":"price difference between cored and coreless motors","faq_answer":"Cored motors are generally less expensive than coreless motors. Coreless motors are more responsive, consume less power, and are more expensive to manufacture."},{"faq_question":"is it possible to custom design a coreless motor?","faq_answer":"Yes, we can custom design to meet your needs.
