The rotary transformer is a core sensor for the drive motor in new energy electric vehicles. It utilizes the principle of electromagnetic induction to convert the rotor's angle, speed, and direction into sine and cosine electrical signals, quickly transmitted to the motor controller ,millisecond-level dynamic closed-loop control. It is regarded as the "nervous system" of the motor, precisely controlling every degree of rotation.
SDM's new energy electric vehicle rotary transformer has significant advantages . It uses micron-level winding technology , making it suitable for high-speed motors. The rotor is constructed from silicon steel laminations and is combined with high-temperature insulation materials. , Suitable for a wide range of complex environments.
