in BEV traction motor, why do we use resolver but not analog hall-sensor?

The reason that a resolver is often used in BEV traction motors instead of an analog hall-sensor is because a resolver provides more accurate and reliable feedback on the motor's position and speed. Resolvers are also able to handle high temperatures and harsh environments better than hall-sensors.

in BEV traction motor, why do we use resolver but not analog MR sensor?
Resolver is preferred over analog MR sensor in BEV traction motor because resolver offers high accuracy, reliability, and durability even in harsh operating conditions such as high temperatures, high vibrations, and high electromagnetic interference. Moreover, resolver provides absolute position feedback without requiring initialization or calibration, which is essential for precise motor control and efficient energy conversion. In contrast, analog MR sensor is more susceptible to noise, temperature drift, and mechanical wear, which can compromise the performance and safety of the motor.
how to implement inter-lock check among hv-voltage controllers in BEV?
The implementation of inter-lock check among HV-voltage controllers in BEVs can be achieved through various methods, such as using a master-slave communication protocol, hardware interlock circuits, or software-based interlock mechanisms. The specific approach may depend on the design of the BEV and the requirements of the interlock system.
