The invention relates to the field of motors, heat energy and power, in particular to a motor and an engine using the same.

Background

The motor with the commutator is in a form that the commutator is fixedly connected with the rotor, and when the motor is used as a generator, the motor still can cause the relative motion between the commutator and a commutator brush, further causes the occurrence of the conditions of commutator brush abrasion and the like, and influences the reliability of the motor and a system thereof. If a motor without the rotating movement of the commutator can be invented and the motor is used as a motor, the normal operation of the motor is realized by utilizing the sliding contact conductive relation between the commutator and the brush of the commutator, and when the motor is used as a generator, the external power supply is realized by utilizing the non-sliding contact conductive relation between the commutator and the brush of the commutator or the external power supply by utilizing a tap on a winding connected with the commutator, so that the motor has good motor performance and good generator performance and works reliably. Moreover, the motor can be used as a starter and a generator of the engine at the same time, so that the number of accessories of the engine system is reduced, and the reliability is improved. Therefore, a new type of motor and an engine using the same need to be invented.

In embodiment 7 and its convertible implementation, when the engine needs to be started, the electric machine can be used as a starting motor and a generator of the engine, when the engine needs to be started, a power supply supplies power to the electromagnet 8 through the electric ring 5, under the action of the electromagnet 8, the electromagnet 8 and the magnetizer 7 mutually magnetically interact and transmit, so that the commutator brush 4 correspondingly arranged is in contact with the commutator 3, the power supply supplies power to a winding on the electromagnetic counterpart a1 through the electric ring 5 and the commutator brush 4 which are electrically communicated, and the commutator 3, and under the mutual magnetic action of the electromagnetic counterpart a1 and the electromagnetic counterpart B2 correspondingly arranged, the electric machine operates according to the working mode of the electric motor, thereby realizing the starting of the engine; when the motor is in a power generation state, power is not supplied to the electromagnet 8, the electric ring 5 and the commutator brush 4 do not rotate along with the electromagnetic corresponding body B2, the electromagnetic corresponding body B2 is driven to rotate by the power shaft of the engine, and under the mutual magnetic action of the correspondingly arranged electromagnetic corresponding body A1 and the electromagnetic corresponding body B2, a winding on the electromagnetic corresponding body A1 generates current and supplies power to the outside. Specifically, when power is supplied to the outside, the current generated by the winding on the electromagnetic counterpart A1 can be selectively and sequentially supplied to the outside through the commutator 3, the commutator brush 4 and the electric ring 5; when the motor is in a power generation state, a power supply interface is preferably arranged on the winding of the electromagnetic correspondent body A1, and the winding on the electromagnetic correspondent body A1 can generate current to supply power to the outside through the power supply interface.

As alternative embodiments, the motors described in examples 1 to 4 and example 6 and their alternative embodiments and the alternative embodiment of example 5 of the present invention can be substituted for the motors described in example 7 and its alternative embodiment.
