Applications - Automotive
Significantly smaller and lighter motors are possible by employing bonded Neo magnets. The weight savings will help automotive companies reduce the total weight of their cars to meet fuel efficiency and performance goals. The Magnequench Applications Design Team has studied various applications by acquiring and benchmarking common existing motors, then "virtually" redesigning these motors.

Of the current MQA anisotropic powder portfolio, MQA-37-11 has the lowest coercivity, which is well suited for applications subjected to working environments not exceeding 80 degrees centigrade. This material also lends itself quite well to certain calendaring manufacturing processes, given the relative low coercivity and high remanence values.

MQA 38-14 has been tailored for use in indoor automotive accessory motors but can be used in a wide range of applications, including home appliance motors. The majority of these motors require material that can operate in temperatures reaching 120 degrees centrigrade. MQA-38-14 maintains its magnetic properties at this temperature in part due to its chemical composition.
