It s not like I have to start it ten times a day; just once a week or so. I installed the new motor on my mower and got it running.
6 FAQs about [Can a high-power motor be pulled without changing the battery ]
What happens if a motor fails to turn?
If a motor fails to turn with any load attached, it may consume a large amount of current, leading to a potentially dangerous situation. This is similar to a car that may not start due to a weak battery. If left unchecked, this scenario can result in serious consequences.
Can a low battery destroy a starter motor?
Someone said that a "dying or low battery in car or motorcycle will destroy the starter motor...because the motor will respond to reduced voltage by increasing the AMP draw...thus causing too much heat". I don't think this is true...well, not exactly. (BTW- I also think heat is a function of WATTS not amps per say...am I wrong?)
Why does a motor need more power?
Think of bearings as the joints of a motor. If these joints are creaky or damaged (like a rusty bike chain), the motor has a hard time turning smoothly. This creates friction and resistance, making the motor struggle to spin. To overcome this difficulty, the motor needs more power, which translates into higher current draw.
What happens if a motor is low voltage?
With a lower applied voltage to the motor not only will the motor be turning slower, which reduces the back EMF and allows more current to flow, the losses such as the internal battery resistance, the cable loss and the IR drop in the motor become more important.
Is a large motor bad for your electrical supply?
It is however bad for your electrical supply (if it is a large motor) - as it needs to supply the current - and the power system will experience higher losses overall (I^2R), and not deliver any power. ( Like the mailman driving by your house - but you get no mail )
Why can't I power a motor that is mechanically locked?
That's why you shouldn't power a motor that is mechanically locked. It cannot build up that counter voltage and will burn out quickly. If you put external torque on the running rotor, the speed decreases and so does the counter-voltage, which leads to more current running through the rotor which creates a counter-torque.
