Lisävääntömomenttia

Lisävääntömomenttia refers to the additional torque that can be generated by an electric motor beyond its baseline output. This is often achieved through a temporary boost or an overdrive function, allowing for enhanced acceleration or the ability to overcome higher loads. In the context of electric vehicles, it enables quicker starts from a standstill or more responsive overtaking maneuvers. The term can also be applied to other types of electric motors used in industrial or domestic applications where a temporary surge in rotational force is beneficial.

This increased torque is typically achieved by momentarily increasing the current supplied to the motor windings. This higher current creates a stronger magnetic field, resulting in a greater force applied to the rotor. However, this is usually a short-term capability, as sustained operation at these elevated levels can lead to overheating and potential damage to the motor. Therefore, systems that provide lisävääntömomenttia often incorporate thermal management strategies to prevent overheating. The duration and magnitude of this added torque are usually defined by the motor's design and the control system managing its operation. The specific implementation and benefits of lisävääntömomenttia vary depending on the application, from improving the performance of electric cars to enhancing the capabilities of power tools.
