Abstract

This invention relates to double-electrode permanent direct current motor, which comprises permanent magnetic materials, soft magnetic materials, and electron technique and mechanic process. The invention is aimed to develop permanent magnetic energy and fully uses electricity power and can be widely used in industry, agriculture, aviation, sailing, military, traffic, and study fields. Comparing with current motor, the invention adopt negative rotation as an ideal power.

Description

technical field [0001] The invention relates to a direct current motor, in particular to a bipolar permanent magnet direct current motor with reasonable structure and high efficiency. Background technique [0002] The existing DC motor has low power conversion efficiency, backward structure and unreasonable magnetic circuit design. In view of this, a structural form is provided, which can exploit the permanent magnet energy to the greatest extent, increase the utilization efficiency of electric energy, and solve the power of the electric vehicle. Exactly where the present invention's research and creation motivation lies. Aiming at the shortcomings of the prior art, the object of the present invention is to provide a DC motor, which realizes a low-cost and practical bipolar permanent magnet DC motor by using permanent magnetic materials, soft magnetic materials, electronic technology and mechanical manufacturing . Contents of the invention [0003] The stator of the pre...
