CAN A DC MOTOR WITHSTAND 5 TIMES IT'S NORMAL RECOMMENDED VOLTAGE??
A normal DC Motor can only withstand 15V, But how could this one work at 63V?
Lorentz Law
This law simply states that ''The total force acting on a charged particle due to electric and magnetic fields is equal to the sum of the electric and magnetic forces acting on it''
Or to put into simple words when a shaft kept in a magnetic field, a current-carrying conductor gains torque and develops a tendency to move
What is the capacity of a Motor?
It actually varies from motor to motor. There are so many types of motors. DC Motors(most commonly used in projects), stepper motors(Real life applications such as 3D printers), Servo motors(Arduino projects), AC Motors(Real life applications such vending machines), brushless motors(to make drones), mini motors(project drones)
But What About DC Motors?
A typical DC Motor used in projects operates at the optimum voltage of 6-12V. Anything above than that, they may create immense noise due to loose or damaged bearings. Sometimes the motors may explode but most of the times the coil inside the motor just burns out due to excessive electricity passing through it
Now what if the motor
exceeds it's capacity?
We obviously expect the motor explode, or just rip apart right?
But what if I told you it didn't(in my case)
​
I used 7 Nine Volt batteries to supply a voltage of 63V and the total current was 0.5A as they were connected in series
​
The DC Motor I used was a regular 6-12V DC Motor but could handle the voltage of 63V

How?
We have to dig deeper by looking at the production process. Each DC Motor is not made picture perfect. The number of wounds around the shaft determine the speed at which it rotates. The wounds, more the speed, thicker the copper wire, the more current it can carry(Remember, current and voltage are different components of electricity)
​
So in my case, it's just that the motor during the production phase was accidentally made with thicker wire and more wounds due to which it could reach such a high voltage
