Problems solved by technology

[0004] Using the traditional theory to design the DC electrode structure, when the performance of the motor needs to meet specific requirements, either the outer diameter of the product is large or the length is very long, which greatly increases the overall size and weight of the electrode, which will increase the application of the product in a small space and the difficulty in lightweight environments, which reduces the applicability of the product

Embodiment Construction

[0035] In order to further illustrate the technical means adopted by the present invention and its effects, the following describes in detail in conjunction with preferred embodiments of the present invention and accompanying drawings.

[0036] see figure 1 and figure 2 , the present invention provides a DC motor, comprising: a stator 1, and a rotor 2 accommodated inside the stator;

[0037] The DC motor meets the following conditions:

[0038] 0.9(K1+K2)≤K3≤1.1(K1+K2);

[0039] Among them, K1=D1 / D2, D1 is the outer diameter of the rotor 2, and D2 is the outer diameter of the stator 1;

[0040] K2=(Ns+Nr-1 / P) / (Ns+Nr+1 / P), Ns is the number of poles of the stator 1, Nr is the number of poles of the rotor 2, and P is the number of pole pairs of the DC motor;

[0041] K3=D2 / L, L is the effective length of the rotor.

[0042] see figure 2 and combine image 3 , in the first embodiment of the present invention, the stator 1 includes a casing 11 and a stator magnet 12 dispos...

Abstract

The invention provides a DC motor and an electric tail gate driver. The DC motor adopts optimized design of structures of a rotor and a stator, so that a ratio of an outer diameter of the stator to an effective length of the rotor is close to a sum of a ratio of an outer diameter of the rotor to the outer diameter of the stator and a value determined by number of poles of the stator, number of poles of the rotor and number of pole pairs of the DC motor. Therefore, the size and weight of the DC motor can be reduced while ensuring that the DC motor satisfies the same operation performance demand, and the product applicability is improved.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a DC motor and an electric tailgate driver. Background technique [0002] A direct current machine is a motor that can convert DC electrical energy and mechanical energy into each other. A DC motor can be used as both a motor and a generator. When it operates as a motor, it is a DC motor, which can convert electrical energy into mechanical energy. When it operates as a generator, it is a DC generator, which can convert mechanical energy into electrical energy. The DC motor has the advantages of wide speed regulation range, convenient speed regulation, smooth speed regulation, etc., and has good speed regulation performance. At the same time, the DC motor has a strong overload capacity, a large starting and braking torque, and can withstand frequent impact loads. Frequent quick start, braking and reverse rotation meet the characteristic requirements of various mechanical loads. ...
