Synchronous motor connection diagram. The steady state performance characteristics of the synchronous motor may be studied using the equivalent circuit shown in fig. Some of the key characteristics of a synchronous motor which differentiates it from other motors are as follows. The speed is synchronous and does not depend on load conditions.
It is usually customary to omit the negative sign of the armature current in the phasor of the synchronous motor so in the phasor two we have omitted the negative sign of the armature current. 1 it should be noted that the direction of armature current. The direct current can be supplied from a separate dc source or from a dc generator connected to the motor shaft.
Synchronous motors synchronous motors are three phase ac motors. Comparing this with fig. Characteristics of synchronous motor.
In the below figure we tried to show you pony motor connection to synchronous motor this is not exact arrangement what we use in industries. The phasor diagram for the synchronous motor is given below in the phasor one the direction of the armature current is opposite in phase to that of the excitation emf. This is also similar to pony motor method with some advantages mostly this method employed for large synchronous motors for synchronous motor a dc machine will be connected this dc machine is used as a d c.
