    Tips: Types of Protection of Stainless Steel Motor.

    Overcurrent protection:
    Overcurrent means that the working current of the motor exceeds its rated value. If it takes a long time, it will overheat the motor and damage the motor, so protective measures need to be taken.
    When overcurrent, the current still flows through the normal path, and its value is smaller than the short-circuit current value. Overcurrent is generally due to excessive load or incorrect startup. In order to avoid affecting the normal operation of the motor, the overcurrent protection action value should be slightly larger than the normal starting current.
    Overcurrent protection also requires the protection device to be able to act instantaneously. Overcurrent protection generally uses overcurrent relays.
