Sell cheap motor fan, replace the winding must note the form of the original winding, size and the number of turns, wire gauge, etc., when lost these data, should be obtained from the manufacturer, arbitrarily change the original design of the winding, often make the motor one or several performance deterioration, even can not be used.The AC motor can also be divided into single-phase motor and three-phase motor.According to the structure and working principle can be divided into: DC motor, asynchronous motor, synchronous motor.
The role of motor protector is to give the motor comprehensive protection, in the motor overload, lack of phase, blocked rotation, short circuit, overvoltage, undervoltage, leakage, three-phase imbalance, overheating, bearing wear, stator eccentricity, to report or protect the device.The shell is filled with a certain amount of working liquid. When the pump wheel rotates driven by the prime mover, the liquid in it rotates driven by the blade and enters the turbine along the outer ring of the pump wheel under the action of centrifugal force. The turbine blade is thrust on the same steering so that it drives the production machinery to run.The power transfer capacity of the hydraulic coupler is consistent with the relative liquid filling volume in the shell.
