Abstract

The invention relates to a brake pump direct-drive permanent magnet motor, which comprises a casing and connecting seats mounted at two ends of the casing, each connecting seat consists of an upper connecting seat and a lower connecting seat, a rotor component is arranged between each upper connecting seat and the corresponding lower connecting seat, a stator component is arranged on the outer side of each rotor component, and sealant is filled between each stator component and the casing. An impeller used for blocking water or draining water is arranged in the rotor assembly, and the impelleris fixedly connected with a main shaft arranged in the middle of the connecting seat. After the motor is started, a rotating magnetic field is generated between the stator assembly and the rotor assembly, the magnetic field forms driving torque, and therefore the rotor assembly is driven to rotate around the axis of the main shaft, and the impeller is driven to rotate around the axis of the mainshaft to achieve water blocking or water draining of a gate pump. According to the invention, the stator assembly is hermetically connected with the casing, and the motor has the characteristics of low production and processing difficulty, low cost, high motor reliability, good heat dissipation effect, small motor size and the like.

Description

【Technical field】 [0001] The invention relates to the field of motors, in particular to a gate pump direct-drive permanent magnet motor with simple processing, strong reliability and low cost. 【Background technique】 [0002] The current sluice pump system is mainly used for electromechanical drainage and irrigation, flood control and drainage, or low-lift and large-flow water intake projects combined with drainage and irrigation through submersible electric pump devices. Most of the existing submersible electric pump devices are full-through-flow submersible electric pumps, and their submersible motors adopt a wet stator winding structure, and the coils of the wet stator winding structure are special water-resistant windings manufactured by using the patented multi-layer eutectic co-extrusion winding wire technology The impeller of the water pump is placed in the inner cavity of the motor rotor, and the blades of the impeller are welded into a whole with the inner circle of ...
