At least one permanent magnet is mounted on the disc, and at least one electromagnet and at least one coil are mounted to the frame in rotational magnetic proximity to the permanent magnet. A battery is connectable to the electromagnet and the coil for energizing the electromagnet and for receiving electrical current from the coil for charging the battery. A relay switch controls the transmission of electrical power from the battery to the electromagnet. A sensor generates a signal to the relay switch to activate electrical power to the electromagnet upon sensing that the permanent magnet is positioned with respect to the electromagnet such that a magnetic force generated by the electromagnet would be effective for inducing movement of the permanent magnet and consequent rotation of the disc."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Direct current brushless motor","description":"A motor includes a frame, a shaft rotatably mounted onto the frame, and at least one disc mounted onto the shaft.
