Is the force generated when the motor starts very small?
Thread Content
When the motor pump of the device starts, is its starting torque not very high? If the pump’s shaft is a bit stuck, is it more difficult to start it? Thank you, points for that!
The starting torque is low, and the pump may get stuck, which could result in its failure to start; therefore, it is necessary to thoroughly rotate the pump before attempting to start it
The startup of a motor pump is a process of transitioning from a stationary state to a moving state, and it requires a significant amount of energy. This can be seen from the motor current; typically, the current during startup is nearly ten times the rated current when the pump is operating normally. “If the pump’s shaft is a bit stuck, it will definitely be difficult to start it, or it might not start at all.
The starting torque of the motor is not small; on the contrary, it is quite large. But the movement is slow because there is significant static friction at the beginning, and the motion has to overcome this static friction. So it also consumes a lot of energy. If the shaft gets stuck, it can easily burn out or enter self-protection mode
If it gets stuck, it can’t start. If trying to start it continues, the motor will get damaged. When it’s stuck, it needs to be disassembled, repaired, and then started again.
The starting force of a motor depends on its torque
