The submersible motor, as the "heart" of the submersible pump, plays a crucial role in converting electrical energy into mechanical energy, which in turn drives the flow of liquid.
The submersible motor, the "heart" of a submersible pump, plays a crucial role in converting electrical energy into mechanical energy, which then drives the flow of liquid. Its working principle cleverly combines the principles of electromagnetic induction and fluid mechanics, making it an indispensable power source in modern industry and daily life. This article will guide you to understand the true mysteries of submersible motors!
What is a motor?
A motor is an electromagnetic device that uses the phenomenon of electromagnetic induction to achieve energy conversion or transmission. It is a strong coupled nonlinear effect between electricity and magnetism, a contradictory body with intertwined electricity, magnetism, force, and heat.
The submersible motor as a key component of the submersible pump
(1) The whole machine adopts a unique cooling technology. (2) It is equipped with control devices such as moisture-proof, corrosion-proof, winding, bearing temperature measurement, humidity sensing, and water leakage alarm, setting up a series of performance guarantee systems to comprehensively improve the reliability and service life of the motor operation. (3) The submersible motor operates underwater. Compared with ordinary dry-type motors, the motor design adopts a slender structure with a large rotor and a small stator to increase the heat dissipation area and reduce the motor's operating temperature rise. (4) Low-voltage, low-power motors generally use soft windings and cast aluminum rotors. High-voltage motors generally use molded hard windings and copper bar rotors.
