    What to do if my Nissei Engine motor does not run under no load?

      If the Nissei Engine motor doesn't run without a load, check the power supply and inspect the circuit/wiring parts for defective connections or short circuit plate contact. Also, check the switch and terminal voltage. If these steps don't solve the problem, the stator winding might be disconnected, or the gear/shaft/bearing might be broken.

      Michael WilliamsAug 19, 2025
      If the Nissei Engine motor fails to turn when a load is applied, check the wiring length to address potential voltage drops. Additionally, the motor may be experiencing overload operation, in which case you should lower the load. If these steps don't resolve the issue, the gear might be worn.

      John BarnesAug 22, 2025
      If the Nissei Engine motor does not rotate, generates abnormal heat, and the thermal relay operates, first check the brake connection. Then, inspect the brake gap and adjust if it is too large. Also, check the rectifier and replace it if defective. Finally, inspect the switch and replace/repair it if defective.

    What to do if the clutch and brake do not work on my Nissei Engine?
    • J
      Jacob GibsonAug 25, 2025
      If the clutch and brake do not work on your Nissei Engine, check the connection first. If the connection is correct, the rectifier may be defective and needs replacement. Also, the switch might be defective and needs replacement or repair.

    Why is the braking time long on my Nissei Engine?
    • M
      Mariah McdowellAug 27, 2025
      If the braking time is long on your Nissei Engine, it could be due to oil or dust on the friction plate, in which case you should clean it. The friction plate's life may also be over, requiring a replacement. A large load inertia moment can also cause this issue, so lower the load. Additionally, consider changing the connection to DC switching if it's currently AC switching.

    Why is the vibration large in my Nissei Engine?
    • G
      Gerald MillerAug 30, 2025
      Large vibration in your Nissei Engine may be due to defective installation or a loose bolt, so ensure everything is tightened. The gear might be worn.

    What to do if the start-up is not good and the brake does not work well on my Nissei Engine?
    • D
      David MccarthySep 2, 2025
      If the start-up is not good and the brake does not work well on your Nissei Engine, it could be due to oil or dust on the friction plate, so clean it. The friction plate's life may also be over, requiring a replacement. A large load torque or inertia moment can also cause this issue, so lower the load.

    Why is the sound high in my Nissei Engine?
    • L
      Leah MejiaSep 7, 2025
      A high sound in your Nissei Engine may indicate a damaged bearing or worn gear if the sound is continuous. If the sound is intermittent, it could be due to a scratch on the gear or foreign substance mixture.
