【Product Introduction】
High voltage slip ring induction motor is a high performance rotating motor, the core of which lies in its unique rotor and slip ring design. Its working principle is based on electromagnetic induction and electrodynamics. When the current passes through the stator coil to generate a rotating magnetic field, the rotor begins to rotate under the action of electromagnetic force, and is continuously powered by slip rings and brushes to achieve continuous operation.

Strong Starting Performance
The high voltage slip ring induction motor is equipped with a special slip ring and brush device. When starting, it can effectively reduce the starting current through an external resistor and greatly increase the starting torque. Compared with ordinary cage induction motors, its starting current can be reduced by about 30% - 40%, while the starting torque can be increased by 20% - 30%, which makes it easy to drive high inertia loads to start smoothly and reduce the impact on the power grid.
Adjustable Speed
With the help of slip ring structure, high voltage slip ring induction motor can achieve smooth speed regulation by changing the external resistor. The speed regulation range is wide, generally reaching 50% - 100% of the rated speed.
Structure characteristics of high voltage slip ring induction motor
Stator: Similar to ordinary high-voltage motors, it consists of a stator core and a stator winding. The stator core is usually made of silicon steel laminations to reduce eddy current losses. The stator winding is a key component of the high-voltage slip ring induction motor to generate a rotating magnetic field, and is generally insulated with high-voltage insulation materials to withstand high voltage.
Rotor: The rotor of the high voltage slip ring induction motor is equipped with a slip ring and a brush device, which is one of the main differences from ordinary motors. The slip ring is usually made of a metal material with good conductivity, such as copper or copper alloy, installed on the rotor shaft and connected to the rotor winding. The brush is in close contact with the slip ring, introducing external power into the rotor winding, so that the rotor winding passes current and generates electromagnetic torque.
Insulation system: Since it operates in a high voltage environment, the insulation system of the high voltage slip ring induction motor has high requirements. Both the stator and rotor windings are coated with multiple layers of insulation material and impregnated to ensure that insulation breakdown does not occur under high voltage. At the same time, good insulation is also required between the slip ring and the brush to prevent current leakage.
