It is a small, high-output motor that can be combined with magnetic and optical rotary encoders, as well as various types of planetary and spur gears.
Citizen Micro's DC coreless motors have achieved compactness and high output through excellent precision processing technology and unique winding techniques. (A new φ8 coreless motor has been developed to be used in a wider range of applications than the conventional φ10-24 series.) Selection of precious metal brushes and graphite brushes is possible (for φ13 and above), and the precious metal brushes utilize a unique longevity technology. In addition to standard catalog products, customization is available according to customer requests. (Changes in winding, ball bearings, shaft length, dual shafts, harnesses, etc.) Magnetic and optical rotary encoders, as well as various combinations of planetary and spur gears, are possible. *For details, please request materials or view the PDF data from the download.
Inquire About This Product
basic information
A coreless DC motor is a type of motor that has no core (iron core) in the rotor (rotating part) and consists only of a coil wound in a cup shape. Inside the rotor, a cylindrical magnet is placed. 【Features】 - Since there is no core (iron core), there is no repeated action of attraction and repulsion from the magnet, resulting in no rotational unevenness (cogging) and smooth rotation. Therefore, vibrations and noise are also minimal. - The rotor is formed solely from the coil, making it very lightweight and having a small moment of inertia, which leads to excellent responsiveness and acceleration control. - There are various advantages such as low coil inductance, high efficiency with low current consumption, very low electrical noise, and the possibility of miniaturization.
