What effect does overload protection and overheating protection have on the motor transaxle?

Prevents Damage: Overload protection ensures that the motor transaxle takes appropriate measures to prevent damage to the motor and related electronic components when the motor draws current exceeding its rated load.
Extends Lifespan: By limiting the maximum current the motor can experience during operation, overload protection can extend the motor's service life, reducing the risk of damage caused by excessive load.
Ensures Safety: By preventing the motor from being overloaded, overload protection helps ensure the safe operation of the equipment, reducing the possibility of accidents.
Overheat Protection:

Prevents Overheat Damage: The overheat protection mechanism monitors the internal temperature of the drive bridge and takes measures, such as reducing output power or stopping the motor, when the temperature exceeds a safe range to prevent damage to the motor and drive bridge due to overheating.
Protects the Drive Bridge: Overheat protection is not only designed to protect the motor but also the drive bridge itself from excessive heat, ensuring its stable operation and extending its service life.
Enhances Safety: Overheat protection helps reduce safety risks caused by equipment overheating, such as fire or other damage, ensuring the safety of operators and equipment.
Conclusion:

Overload protection and overheat protection are critical safety features in electric variable speed drive bridges. They ensure the reliability, safety, and longevity of the motor system.
