    Tips: Types of Protection of Stainless Steel Motor.

    Overload protection:
    Motor overload means that its working current exceeds the rated value and the windings are overheated. There are many reasons for the overload, such as a sudden increase in load, a decrease in power supply voltage, and motor bearing wear.
    Overload is similar to overcurrent, but there are also differences. The main difference lies in the action effect. Overcurrent is the electromagnetic effect that triggers the action of the protection device, aiming at the instantaneous magnitude of the current; while the overload protection is triggered by the thermal effect of the current, that is, the cumulative result of the current over time, which triggers the action of the protection device. Generally, in the same circuit, the overload protection action current value is smaller than the overcurrent, and both of them are smaller than the above-mentioned short-circuit protection action current value. It is worth noting that short-circuit protection, over-current protection and overload protection cannot replace each other.
    Overload protection should use thermal relay or motor protector as the protection element.
