Lv induction motor, the so-called low voltage, refers to the AC voltage below 1000V, and the motors we are talking about here are generally asynchronous motors with AC voltages of 380V, 440V, or 660V.

Induction motors are also called "asynchronous motors", which means that the rotor is placed in a rotating magnetic field, and under the action of the rotating magnetic field, it obtains a torque, so the rotor rotates.

Structural Components Of Lv Induction Motor

Stator part:

Stator core: It is made of laminated silicon steel sheets to reduce eddy current loss. Silicon steel sheets are an iron-silicon alloy with a silicon content of about 0.5%-4.5%. They have the characteristics of high magnetic permeability and low iron loss. They can effectively guide the magnetic field and concentrate the magnetic field around the stator winding.

Stator winding: It is a three-phase winding, usually wound in the slots of the stator core with insulated copper wire. The three-phase windings are 120° electrical angle apart from each other in space. When the three-phase AC current passes through, a rotating magnetic field can be generated. There are two ways to connect the winding: star (Y) connection and triangle (△) connection. The connection method will affect the voltage, current and power performance of the motor.

Rotor part:

Squirrel cage rotor: It is the most common rotor structure. Copper or aluminum bars are inserted into the rotor core slots, and short-circuit rings are connected at both ends, which looks like a squirrel cage. This rotor structure is simple, strong, low-cost, good starting performance, and reliable operation.

Wire-wound rotor: It has three-phase windings and is connected to the external circuit through slip rings and brushes. This rotor structure is relatively complex and costly, but by connecting a resistor to the rotor winding, the starting and speed regulation performance of the motor can be improved.
