However, the increased current also causes the motor to heat up. If the motor is operated at too high a current, it can overheat and damage the windings. To prevent this from happening, a flywheel is often used.
A flywheel is a heavy wheel that is attached to the motor's shaft. It stores kinetic energy when the motor is running. When the load on the motor increases, the flywheel releases some of its stored kinetic energy to help the motor turn. This helps to reduce the amount of current that flows through the windings, and thus helps to prevent the motor from overheating.
Flywheels are also used to help smooth out the motor's operation. When the load on the motor changes, the flywheel helps to keep the motor running at a constant speed. This is important for applications where a constant speed is required, such as in industrial machinery.
In addition to preventing overheating and smoothing out the motor's operation, flywheels can also help to reduce the motor's starting current. This can be important for applications where the motor is connected to a weak power source, such as a battery.
Overall, flywheels play an important role in the operation of dc series motors. They help to prevent overheating, smooth out the motor's operation, and reduce the motor's starting current.
