3 PMSM

What is a Permanent Magnet Synchronous Motor (PMSM)?

• A. An electric motor that uses electromagnets on the rotor to create a magnetic field

• B. An electric motor that uses permanent magnets on the rotor to create a magnetic field

• C. An electric motor that uses permanent magnets on the stator to create a magnetic field

• D. An electric motor that uses electromagnets on the stator to create a magnetic field

How does a PMSM generate torque?

• A. By using slip rings to create a rotating magnetic field

• B. By using a fixed magnetic field on the rotor and a rotating magnetic field on the stator

• C. By using a fixed magnetic field on the stator and a rotating magnetic field on the rotor

• D. By using brushes to create a rotating magnetic field

What is the role of sensors in controlling a PMSM?
