Devices from compressors to flywheels could be revolutionized if electric motors could run at higher speeds without getting hot and failing. MIT researchers have now designed and built novel motors that promise to fulfill that dream. Central to their motors are spinning rotors of. .
Designing a motor to turn electricity into movement is tricky. In a typical motor, a component called a rotor turns inside a stationary component called a stator. One of those components. .
To Mohammad Imani-Nejad PhD ’13, Trumper’s graduate student and now a postdoctoral associate in the MIT Laboratory for Manufacturing and Productivity, the. .
With any motor, a major challenge is designing the coils and the currents they carry to create the magnetic fields needed to control the rotor. Methods of making coils for motors with permanent magnets are well understood, but Trumper and Imani-Nejad needed. .
The photo to the right shows the first setup they built. It consists of a rotor sandwiched between two stators, top and bottom. Four sensors entering from the top monitor the position of the rotor,. [pdf]
