Introduction to Electric Motors - STMicroelectronics
www.st.comThe electric motor operation is based on the following points: • At least one of the two magnetic field is generated by a solenoid carrying a current. • Phase relation between the rotor and stator magnetic field (i.e. the load angle) must be always greater than 0° in order to keep the motor in motion (negative angles reverse the rotation).
