Overview of Slip Ring Motor
Slip ring motor, also known as wound rotor motor, is a common type of AC motor widely used in industrial applications. It has the advantages of simple structure, reliable operation and high efficiency. The slip ring motor consists of a stator, a rotor, a slip ring and a collecting ring. The stator and rotor are composed of windings and iron cores. The slip ring and collecting ring are located on the rotor shaft. The slip ring is used to supply power to the rotor winding, and the collecting ring is used to collect the current from the rotor winding.
Construction of Slip Ring Motor
The construction of slip ring motor mainly includes stator, rotor, slip ring and collecting ring. The stator is composed of a stator core and a stator winding. The stator core is made up of stacked laminations that form a hollow cylindrical shape. The stator winding is made of insulated copper wire and is wound in slots in the stator core. The rotor is composed of a rotor core and a rotor winding. The rotor core is made up of a number of laminations that form a cylindrical shape. The rotor winding is made of insulated copper wire and is wound around the rotor core. The slip ring and collecting ring are located on the rotor shaft. The slip ring is used to supply power to the rotor winding, and the collecting ring is used to collect the current from the rotor winding.
Working Principle of Slip Ring Motor
The working principle of slip ring motor is based on the principle of electromagnetic induction. When a three-phase AC power supply is connected to the stator winding, an alternating magnetic field is generated in the stator core. The alternating magnetic field induces a current in the rotor winding, which produces a magnetic field in the rotor core. The interaction between the stator and rotor magnetic fields causes the rotor to rotate. The slip ring and collecting ring are connected to the rotor winding, and the current induced in the rotor winding is supplied to the slip ring and collected from the collecting ring.
Advantages of Slip Ring Motor
The slip ring motor has the advantages of simple structure, reliable operation and high efficiency. It is widely used in industrial applications due to its reliable performance and low maintenance cost. In addition, it is also suitable for variable speed operation and can be easily controlled by a variable frequency drive.
