9.4 Motors
The Motors in this system are AC synchronous motors.
(There are no brushes in these motors.) These motors
operate through the use of magnetic fields. In simplest
of terms, a motor is made up of coils (electromagnets)
around the outside (known as the stator) and permanent
magnets mounted on the part of the motor that rotates
(known as the rotor). The diagram below shows these
components.
To make the rotor rotate, 340 VDC is sent through a set
of coils polarizing the electromagnet and causing the
permanent magnets on the rotor to rotate by either
pulling towards or pushing away from the
electromagnets.
