SPINPad Resolver

AB ELEKTRONIK INTRODUCING SPINPAD, A HIGH SPEED ROTATION POSITION SENSING TECHNOLOGY FOR NEXT GENERATION MOBILITY.
In Battery Electric and Hybrid vehicles a fast and accurate rotor position measurement is essential for efficient E-motor controls. A precise position signal from stand still (0 rpm) to maximum rotation speed (100,000 rpm) is required for a high torque and high efficiency of the traction drive and for more power and extended driving range of the vehicle.


AB Elektronik has developed a new kind of resolver based on an active system in a two PCB design. The High Speed Rotation Position Technology HSRP is based on AB-Elektronik´s mature Autopad®-technology, which is established since 2007 and many million products in field. As the next step in development the new antenna system of the SPINpad and the development of a new IC allows the accurate high speed measurement for the E-motors.


The main components of the inductive system are the static element called Pad, a PCB with its transmitting and receiving antennas and the rotating target as an activated resonant element. The sensor is characterized in its flat envelope, minimal weight and its minimal impact on the rotation and acceleration.


The technology allows a very flexible adaption to the potential E-Mobility applications.
