Non negative torque outer-rotor permanent magnet motor

Abstract

Comparing with same kind of electrical motor, the disclosed permanent magnet motor uses less conduction wire, magnet material, and permanent magnetic material. The disclosed permanent magnet motor possesses features of low cost, high magnetic energy transform, small starting up current, no negative moment, powerful torsion, small power consumption. The motor is applicable to electric automobile, and other dynamical power.

Description

technical field [0001] The invention relates to a permanent magnet motor, in particular to the design of a novel non-negative torque outer rotor permanent magnet motor. Background technique [0002] At present, energy and environmental protection have been the most concerned issues of people. Electric vehicles, electric motorcycles, and electric bicycles have been widely developed and used because of the advantages of tailless steam, safety, and energy saving. However, they require large-capacity livestock batteries and are expensive. The distance of a single electric drive is limited and restricted. How to reduce the negative torque of the permanent magnet motor, improve the effect of the permanent magnet energy, and increase the power output are problems to be solved in the design of this field. Our country is rich in magnetic mineral resources, research and development of the utilization of magnetic energy, design and manufacture of non-negative torque external rotor perm...

Problems solved by technology

[0002] At present, energy and environmental protection have been the most concerned issues of people. Electric vehicles, electric motorcycles, and electric bicycles have been widely developed and used because of the advantages of tailless steam, safety, and energy saving. However, they require large-capacity livestock batteries and are expensive. The distance of a single electric drive is limited and is restricted. How to reduce the negative torque of the permanent magnet motor, improve the effect of the permanent magnet energy, and increase the power output are problems that are tried to be solved in the design of this field.

Our country is rich in magnetic mineral resources, research and development of the utilization of magnetic energy, design and manufacture of non-negative torque external rotor permanent magnet motors, and convert more magnetic energy into mechanical energy is a difficult problem for human research. Related permanent magnet motors have been retrieved and published or authorized , there is a negative torque problem in the rotation process, the load is large, and the power consumption is large, which cannot meet the ideal requirements of practical applications.
