SYN motor is inherently a twophase or a threephase device, depending on model, a phase shifting network is required to convert the singlephase excitation into the two or threephase excitation required. Twophase motors require a resistor and a capacitor for the phaseshifting network, while threephase motors need only a capacitor. The connections in Figure 6 are for a twophase motor.

BLDC motors are a type of synchronous motor. This means the magnetic field generated by the stator and the magnetic field generated by the rotor rotate at the same frequency. BLDC motors do not experience the "slip" that is normally seen in induction motors. BLDC motors come in singlephase, 2phase and 3phase configurations.

There are two basic types of stepper motors, unipolar steppers and bipolar steppers. Unipolar Stepper Motors. The unipolar stepper motor has five or six wires and four coils (actually two coils divided by center connections on each coil). The center connections of the coils are tied together and used as the power connection.

The stator then is the stationary part of the AC motor. The rotor is the rotating electrical component. It also consists of a group of electromagnets arranged around a cylinder, with the poles facing toward the stator poles. The rotor is located inside the stator and is mounted on the AC motor's shaft.

A synchronous motor's construction is similar to that of an induction motor. The stator currents produce the RMS, which rotates in synchronous speed ( n s ). The rotor spins together with RMS in equal speed ( n = n s ) and the motor is synchronized.

For this machine, however, because the stator must be connected to the threephase circuit, the difference between being a motor or functioning as a generator lies in the speed of the rotor. In general, if the rotor speed is higher than the synchronous speed, then it behaves as a generator, and if the rotor speed is less than the synchronous speed, it becomes a motor .
