Model 550 Ac Synchronous Electrically Reversible Motor
Synchronous motor connection diagram. The torque developed in a synchronous motor is directly proportional to the applied voltage unlike in an induction motors where it is proportional to the square of voltage. Single motors connected to captive transformers shall be capable of overcoming the inertia of the load on starting as well as accelerating the load to rated speed under both rated and 70 percent of the rated voltage conditions or voltage conditions specified on data. Owing to its characteristics to behave at any electrical power factor it is used in power system in situations where static capacitors are expensive. Synchronous motors contain multiphase ac electromagnets on the stator of the motor that create a magnetic field which rotates in time with the oscillations of the line. Figure 6 contains a diagram showing the connections for operating a slo syn motor as a three lead reversible motor from a single phase source. Since a slo syn motor is inherently a two phase or a three phase device depending on model a phase shifting network is required to convert the single phase excitation into the.
In this lesson well learn to read and interpret motor connection diagrams and determine the electrical relationship of the stator windings using motor connection diagrams. Electronic synchronous motor. Application of synchronous motors. Synchronous motor finds application where operating speed is less around 500 rpm and high power is required. A synchronous electric motor is an ac motor in which at steady state the rotation of the shaft is synchronized with the frequency of the supply current. We can supply different types of motors like synchronous motor dc gear motor stepper motor brushless motor etc in order to help customer connect.
The rotation period is exactly equal to an integral number of ac cycles. A synchronous electric motor is an ac motor distinguished by a rotor spinning with coils passing magnets at the same rate as the alternating current and resulting magnetic field which drives it. These motors have a position sensor integrated within the motor which provides a low level signal with a frequency proportional to the speed of rotation of the motor. Synchronous motor having no load connected to its shaft is used for power factor improvement.

The power angle characteristics of both types of rotor are shown in fig. The block diagram shows the drive electronics associated with a low voltage 12 v dc synchronous motor. The stepping motor is transformed into a synchronous motor by replacing the wound wire for the ac power specification. A synchronous motor rotates at a constant speed in proportion to the ac power. Power angle diagram of synchronous motor. All motors shall be designed for across the line starting at full rated voltage.
