Problems solved by technology

[0002] Starter generators are widely used in the new energy electric vehicle industry, construction industry and other related industries. The current starter generators drive the central shaft to rotate through an external power source to cut the magnetic field lines for power generation. The power generation method of the outer stator and inner rotor is adopted. The diameter is small, the power generation efficiency of this power generation method is low, and because the mass of the central shaft is small, the rotational inertia is low, and the generator requires a large start-up energy consumption

Embodiment 1

[0035] Such as Figures 1 to 3 As shown, the present invention provides a starter generator, including a fixed shaft 1, a transmission wheel 2 sleeved on the fixed shaft 1 and rotatably connected to the fixed shaft 1, and a housing 3 arranged on the transmission wheel 2. The transmission wheel 2 It is connected to the external power source by transmission, and the housing 3 is equipped with a power generation assembly. The power generation assembly includes an excitation coil 4 arranged on the fixed shaft 1 and a permanent magnet 6 arranged on the inner wall of the housing 3. The excitation coil is arranged on the fixed shaft 1 4. A permanent magnet 6 is set on the inner wall of the casing 3. Since the casing 3 is set on the transmission wheel 2, the permanent magnet 6 rotates together with the transmission wheel 2, thereby cutting the magnetic force line to generate power. Through the setting of the outer rotor inner stator, The rotor is fixed on the housing 3. The housing 3 ...

Embodiment 2

[0054] Such as Figure 4 As shown, the main difference between this embodiment and the first embodiment is that the casing 3 includes a first casing 31 and a second casing 32 .

[0055] The casing 3 includes a first casing 31 and a second casing 32, and the transmission wheel 2 is arranged between the first casing 31 and the second casing 32. The benefit of such an arrangement is that both ends of the transmission wheel 2 can be The power generation component is arranged so that the weights at both ends of the drive wheel 2 are more balanced, the use of the generator is more stable, and the power generation of the generator is increased, so that the power generation of the generator is more efficient.

Embodiment 3

[0057] Such as Figure 5 As shown, the main difference between the present embodiment and the first embodiment is that there are multiple power generating components arranged parallel and parallel inside the casing 3 along the axial direction of the casing 3 .

[0058] There are a plurality of power generating components arranged parallel to the inside of the housing 3 along the axial direction of the housing 3 . The advantage of such arrangement is that the power generation of the generator is increased and the power generation of the generator is more efficient. In this embodiment, there are two groups of power generation components, and the specific number can be selected according to the power generation capacity.

[0059] It can be understood that the power generation components can also be provided with 3 groups, 4 groups, 5 groups, 6 groups and so on.

Abstract

The invention provides a starter generator, which comprises a fixation shaft, a driving wheel sleeved on the fixation shaft and in driving connection with the fixation shaft, and a housing arranged onthe driving wheel. The driving wheel is in driving connection with an external power source; and the housing is internally provided with a power generation assembly. The power generation assembly comprises an excitation coil arranged on the fixation shaft and permanent magnets arranged on the inner wall of the housing. Since the housing is arranged on the driving wheel, the permanent magnets rotate with the driving wheel, and magnetic force lines are cut to generate power; through arrangement of an outer rotor and an inner stator, the rotor is fixed to the housing, the housing not only playsa protection effect, but also increases the weight of the rotor to enable rotational inertia of the rotor to increase, so that under the condition of the same power, start energy consumption of the generator can be reduced, and the generator is allowed to be started more economical and efficient; and the housing is externally provided with a counterweight member for increasing the rotational inertia of the housing to increase, and thus the generator is allowed to be started more economical and efficient.
