The invention relates to an engine provided with a plurality of 
magnet-wheels, which consists of a permanent 
magnet (1), an 
electromagnet (2), an 
electromagnet seat (3), an electric conduction 
copper ring (4), a straight shaft (5), a bearing (6), an end cover (7), a shell (8), a spoked wheel (9), a 
spoke (10), a carbon 
brush holder (11) and a carbon 
brush (12), and has the advantages of light weight, simple structure, no 
tail gas emission, 
energy conservation, etc. The engine combines part of the technology of a 
steam turbine with magnetic force, and has the advantages of large arm of force and moment as well as no dead center. By properly selecting the number of the spoked wheels (9) and the number of each line of spokes (10), the area of a magnetic pole, the intensity of a 
magnetic field and the length of the 
spoke (10) are properly chosen, and the engine having the required power can be designed, thus making contribution to opening up new power source. The principle of the action of the engine is that 
repulsion force is generated between the like 
magnetic poles which are the permanent 
magnet (1) and the 
electromagnet (2), component force which is vertical to the radial direction of the 
spoke is generated when the 
repulsion force is transmitted to the inclined plane at the end of the spoke (10) used for fixing the permanent magnet (1), and moment is formed; while, the same moment with opposite direction is generated by another spoke (10) which is symmetrical with the spoke (10) along the radial direction; the two moments form torque force to lead the straight shaft (5) to rotate.
