Abstract

The invention discloses a single-pole motor, comprising a casing, wherein two ends of the casing are each provided with an end cover, a rotating shaft rotatably connected with the end cover is arranged in the casing, a rotor is fixedly arranged on the rotating shaft, a stator corresponding to the rotor is arranged in the casing, and an air gap is arranged between the rotor and the stator. The stator includes at least one stator core, one side of the stator core facing the rotor is provided with a plurality of magnetically conductive internal teeth extending along the axial direction of the rotating shaft side by side, one side of the stator core away from the rotor is provided with magnetically conductive external teeth extending obliquely outward side by side, an armature winding is arranged on the stator core, and a plurality of internal teeth slots perpendicular to the rotating shaft are arranged on the magnetically conductive internal teeth. When the rotating shaft rotates, a magnetic field in the stator core is a steady magnetic field, and there is no iron loss. Since each turn of a coil in the armature winding generates an electromotive force in the same direction, the voltage generated after the coils are connected in series is very high, and the current is very low. The motor is large in capacity, high in efficiency and low in price, and is reliable to use.

Description

technical field [0001] The invention relates to a motor, in particular to a unipolar motor. Background technique [0002] In 1831, Faraday discovered the phenomenon of electromagnetic induction. Soon, he used the principle of electromagnetic induction to invent the world's first generator - the Faraday disc generator. After more than 100 years of improvement and development, it has formed a modern structure. Unipolar motor. At present, unipolar motors are widely used in smelting and electrochemical industries. However, due to the low output voltage of the unipolar motor, the general output voltage is only a few volts or a dozen volts, and the output current is large. High, large loss, fast wear, and cannot be used for mechanical dragging, so its application range is greatly limited. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a unipolar motor with high output voltage, low current, stable and reliable use, ...
