<p>A multi-stage servo oil submersible motor mainly comprises a motor body. The motor housing of the head portion of the motor body is connected with a head flange. The head portion of a motor shaft protrudes out of the head flange, and the motor shaft is fixed within the head flange and connected with other devices by the head flange. Multiple stages of motors are provided in the motor body, and each stage of motor mainly includes a stator and a rotor within its motor housing (800). The rotor is a permanent magnet, and windings are provided in a stator core. The rotor shafts (805) of two adjacent stages of motors are connected by a shaft coupling (804), and the motor housings of two adjacent stages of motors are connected by a connecting means. The N poles of the rotors provided on two adjacent stages of motors are correspondingly provided in line, S poles thereof are correspondingly provided in line, and three-phase windings U, V, W in the stators are correspondingly provided in line, respectively. The multi-stage servo oil submersible motor is simple in assembling structure, and can be operated easily and provide higher power.</p> |
