This is because the motor requires a considerable amount of current at the moment of startup, and the amount of heat generated is proportional to the current level – the greater the current, the more heat is produced. During the first startup, a lot of heat is generated within the windings; if the startup attempt fails and another attempt is made, the heat from the previous attempt has not yet dissipated, and additional heat is added, causing the temperature to rise sharply, which can damage the motor or the switch. To boost the popularity of this section and help new members grow more quickly, the Petrochemical Deep Processing section is launching the 【One Question per Day】 campaign starting today, offering generous rewards to those who participate! The rewards are as follows: Participating in the quiz earns +2 wealth (wealth is added automatically). +3 wealth for each correct answer. If an analysis and explanation of the question or answer is provided, +5~8 wealth. First responder to the daily question: One flower. Note: We will close this thread after 48 hours to reveal the answer and explanation. The moderator has the final say on this post; if there are any questions, discuss them in this thread.

The motor cannot be started continuously. (Correct)
The motor cannot be started continuously. (√)
Correct--------------------------------
The motor cannot be started continuously. (Yes)
The motor cannot be started continuously. (right)
Answer: Yes. There are several reasons: 1. The capacity and stability of the power grid itself; 2. The performance of the motors and transmission mechanisms; 3. The continuous nature of the load, such as the difference in load magnitude between forward and reverse operation
Correct, at the moment the motor starts, the current is high and the torque is large, which can easily lead to other problems.
