{"product_id":"156554","title":"42SI-22DAG","description":"\u003cp\u003e12V 24V 7.5DEG 50OHM MOTOR - permanent magnet (tin-can) stepper motor. This specific line of motors was widely manufactured in Japan during the 1980s and commonly used for precise sub-assembly movements, such as paper feeding and print head positioning in legacy dot-matrix printers (e.g., Commodore, Epson, and Apple printers) and vintage disk drives.Technical Specifications BreakdownManufacturer: Mitsubishi (Japan)Model\/Series: 42SI (42mm outer frame diameter)Variant Code: 22DAG (Denotes the specific internal winding arrangement, lead count, and physical shaft\/gear configuration).Step Angle: 7.5 Degrees per full step. This splits a full rotation (360°) into exactly 48 steps per revolution.Phase Resistance: 50 Ohms DC winding resistance. This indicates a high-impedance coil designed for low-current, voltage-driven (L\/R) control topologies or simple unipolar\/bipolar circuit arrays.Mechanical FeaturesMotors in the 42SI series typically feature a cylindrical \"tin-can\" body with an integrated front mounting flange. The output shaft often comes equipped with a pre-installed brass or steel spur gear designed to interface directly with a printer's carriage drive belt or gear train.Wiring ConfigurationWhile variant suffixes alter wire colors, these Mitsubishi 42SI motors are generally configured as 6-wire unipolar or 4-wire bipolar setups. If your motor has 6 wires, it features two independent coils, each with a center-tap wire to allow easy driving via simple transistor arrays (like a ULN2003 or Darlington pair).\u003c\/p\u003e","brand":"MITSUBISHI","offers":[{"title":"Default Title","offer_id":67588500717621,"sku":null,"price":25.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0219\/7936\/5440\/files\/AP1GczMZPNL9gv8K3mwvLbM26f42WSOZOUDX9aJVflr1KmZTM2x4WLazw28vLIUuPESw6VBgE76DZP_odD4HDQ7jcBoUEtkXrDC_sxHBxgyg2XHBntO56k2fRun8OblfNIyhZ6t2KmzYUj-18b43qkuFq4fEug_w1794-h1794-s-no-gm.jpg?v=1790724607","url":"https:\/\/greenbrookonline.com\/products\/156554","provider":"Green Brook Online","version":"1.0","type":"link"}
