Abstract

The invention discloses a spherical motor for an electric bicycle. The spherical motor comprises a stator and a rotor, wherein the stator is fixedly arranged on a fixing shaft, the rotor can rotate in the circumferential direction of the fixing shaft, a wire winding group is arranged on the stator, a plurality of permanent magnetic bodies are arranged on the rotor, the rotor is in a hollow spherical shape, the permanent magnetic bodies are fixedly arranged on a hollow inner case of the rotor, the fixing shaft passes through the spherical center of the rotor, the stator is in a solid spherical shape provided with the wire winding group at the inside, the fixing shaft passes through the spherical center of the stator, the radius of the stator is smaller than the radius of the rotor and is arranged in the hollow part of the rotor, and the direction of a magnetic field generated after current is introduced into the wire winding group is vertical to the spherical surface of the rotor in the corresponding position. The spherical motor provided by the invention has the advantages that the rotor and the stator are both designed into the spherical shape, the sum of the sizes of the permanent magnetic bodies accommodated inside the spherical rotor is great, meanwhile, the heat radiation area is large, the distance between the spherical stator and the rotor is small, the energy conversion rate is higher, and meanwhile, the heat radiation performance is better.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a spherical motor used in an electric vehicle and an electric vehicle using the spherical motor. Background technique [0002] The motor is an electromagnetic device that realizes the conversion or transmission of electric energy according to the law of electromagnetic induction. Its main function is to generate driving torque as a power source for electrical appliances or various machinery. A conventional motor is divided into two parts: a stator and a rotor. The stator is the stationary part of the motor and is mainly used to generate the magnetic field. The rotor is the rotating part of the motor. The main function of the rotor is to induce electromotive force or generate electromagnetic torque, which turns mechanical energy into electrical energy (generator) or electrical energy into mechanical energy (motor). When the motor is working, it generates induced electromotive for...
