What Are the Characteristics of the Motor Slip Ring?

The motor slip ring generally refers to the slip ring motor, also known as the three-phase wound rotor AC asynchronous motor. It is necessary to connect a resistor or reactor in series in the motor rotor circuit to reduce the starting current and increase the starting torque. Improve, effectively improve the motor starting performance. Therefore, in mechanical equipment with large capacity and high requirements on rotating torque, this kind of motor is usually used for dragging.

In the process of starting and working of the slip ring motor, once it encounters special situations such as locked rotor, excessive voltage drop, low pressure load, low voltage, mechanical jam, etc., due to the speed reduction, the pressure of the contacts, sheets and sheets inside is reduced, and the electrical conductivity is reduced. Bad, the liquid is heated and the liquid is sprayed outward. When the spraying liquid is small, only pure water is added, and the following starting liquid formula is used to supplement the liquid when the spraying is almost complete.

The treatment method of the insufficient cooling air volume of the slip ring coaxial:

Take measures to increase cooling ventilation, such as external installation of axial fans for cooling. When the temperature of the brush or slip ring is high, the fan can be started to strengthen the surface heat exchange, and the cooling effect is ideal. Regularly use dry and clean compressed air to blow the dust and powder of the slip ring, remove the dust on the outer cover of the slip ring, check and clear the small holes of the slip ring after shutdown, and check and clean the air inlet filter.
