Post Minebea Hybrid Nema 17 stepper motor (HCROBO0030)


These motors rotate at fixed angles by using digitally controlled electronic pulses. Hybrid-type stepping motors combine a rotor with a permanent magnet and a magnetic body using ball bearings. Bearings are crucial to motor precision. Minebea's hybrid type stepping motors use high-precision ball bearings manufactured in-house, greatly contributing to the precision and reliability of these products.

The Minebea hybrid stepper motor is similar in design to the Nema 17 specification, making it ideal for use in robotics, 3D printers and CNC applications.
