What to do if the Hiwin EM1 Industrial Equipment motor can't rotate at all?
- K
  Katie CampbellAug 7, 2025
  If the Hiwin Industrial Equipment motor doesn’t rotate, several issues could be the cause. First, examine the cable connected to the controller for incorrect wiring. Second, verify that there are no interfering objects causing a current overload and address any brake clamping failures. Third, review the controller's over-temperature settings. Lastly, if the issue persists, measure the insulation resistance after cooling, ensuring the stator three-phase to ground (U/V/W to PE) reads >10 MΩ at 500 VDC for 1 second at the specified temperature. Contact HIWIN if it does not reach 10 MΩ.

Why is my Hiwin EM1 motor experiencing unstable rotation (vibration)?
- D
  David DeckerAug 12, 2025
  If your Hiwin Industrial Equipment experiences unstable rotation (vibration), several factors could be responsible. Begin by checking if the resistance value of phase/earth is larger than 10 MΩ to exclude insulation failure. Next, verify the installation stiffness of the encoder and ensure the encoder connection is correct. Also, inspect the controller settings and motor parameters settings.

Why Hiwin EM1 motor cannot be rotated manually without connecting the controller?
- Y
  youngalexanderSep 2, 2025
  If the Hiwin Industrial Equipment motor cannot be rotated manually without connecting the controller, it could be due to mechanical interference, so remove any interference. Alternatively, there may be a motor three-phase short circuit, which needs to be fixed.
