Thus, direction of magnetic field and the direction of armature current reverses in such a way that the direction of force experienced by armature conductors remains same. Hence, as polarity of AC changes periodically, the direction of current in armature and field winding reverses at the same time. Because, armature winding and field winding are connected in series, they are in same phase. We can calculate the total turns ratio by calculating the voltage ratio ( primary. sp( s) sp 0 NNsind2N Actuators & Sensors in Mechatronics: Brushless DC Motors K. When fed with AC supply, it still produces unidirectional torque. So if the windings are sinusoidally-distributed in space, then the mmf dropped across the air gap will also be sinusoidal in space. The axis of the compensating winding is 90 o (electrical) with main field axis. Friends page Engine Two Stroke Engine,Four Stroke Engine,single cylinder Engine,multi cylinder Engine,C.I Engines,S. In this type of motor, the compensating winding is connected in series with the armature circuit. The direction of this force is given by Fleming's left hand rule. Given below is the circuit diagram of the conductively compensated type of motors. Due to this mechanical force, or torque, the rotor starts to rotate. When a current carrying conductor is placed in an electromagnetic field, it experiences a mechanical force. The same current also flows from the armature conductors. When current flows in the field winding, it produces an electromagnetic field. Then the power supply to the prime mover is disconnected so that the synchronous machine will continue to operate as a motor. When the universal motor is fed with a DC supply, it works as a DC series motor. Transformers can provide a voltage on their secondary winding but to transfer electrical power between their input and output they need to.
