Slip ring motor start and work process, once encountered locked-rotor, excessive voltage drop, pressure load, low voltage, the special cases such as mechanical jammed, due to lower the speed, the inside of the contact, less stressful, piece and piece conductive bad, hot liquid spray outward. The spray is not only supplemented with pure water, but the following starting fluid formula is used to replenish the liquid.
Slip ring motors, also known as the three phase ac wound rotor asynchronous motor, must be concatenated in the motor rotor loop resistance or reactor, can reduce starting current, the starting torque, power factor, effectively improve the motor starting performance. Therefore, in mechanical equipment with high capacity and high demand for torque torque, this kind of motor is usually used for dragging.
