Problems solved by technology
At present, the stator shell, base and thrust bearing seat of the YQS125 submersible pump motor are connected by integral threading, so that the rotor cannot use a larger bearing, the rotor deflection is large, the design air gap is large, the power factor of the motor is low, and the power is small; Therefore, designing a YQS125 submersible pump motor that uses larger bearings when the diameter of the motor shell is constant is a technical problem that needs to be solved at present

Description
technical field [0001] The invention relates to a submersible pump motor, in particular to a YQS125 submersible pump motor. Background technique [0002] As we all know, for motors with the same rated voltage, the larger the volume of the stator / rotor, the larger the diameter of the coil, the smaller the number of turns, and the greater the power, and vice versa. In the case of the same diameter of the motor shell, in order to increase the volume of the stator / rotor of the motor, the length of the stator / rotor must be increased. In addition, the air gap is the gap between the stator and rotor of the motor. Generally, the air gap is between 0.2 mm and 1.6 mm. It is not good if it is too large or too small. If it is too large, the power factor will be reduced. If it is not good, it will cause friction between the rotor and the stator, and the influence of the high-order harmonic magnetic field will increase; the greater the length of the rotor, the greater the deflection, and...
