Embodiment 1

[0020] Embodiment one, as figure 1 As shown, the present invention provides a distributed arc motor, including at least two arc motors 4, the arc motor 4 includes an arc-shaped stator 1 and a corresponding rotor 3 with the same number of pole pairs, and at least two arc motors The stator 1 of the motor forms a circle, and the rotor 3 is located inside the stator 1, forming an inner rotor motor; its motion principle is like a magnetic levitation railway track or a linear motor, there is no fixed corresponding relationship between the stator 1 and the rotor 3, according to the magnetic levitation DC motor The principle of maglev rail transit that we can see in our daily life is understood as a motor with an infinite radius, a maglev train is equivalent to a distributed motor of a linear motor, and multiple maglev trains are distributed motor. The technical product of the present invention is to change the infinite radius into a finite radius, so that the rotor of the magnetic l...

Embodiment 2

[0022] Embodiment two, such as figure 2 As shown, the rotor 3 of the circular arc motor is arranged outside the stator 1 to form an outer rotor motor, and the rest is the same as the first embodiment.

Abstract

The invention discloses a distributed arc motor, and the motor comprises at least two arc motors, wherein each arc motor comprises an arc-shaped stator and a corresponding rotor with the same number of pole pairs. The stators of the arc motors form a circle. The setting of the arc motors enables the torque to be very high during a low rotating speed, and the enables the power density to be very high, and enables the start torque to be large. The number of the distributed motors in operation can be changed according to the needs, thereby achieving the power adjustment. When one arc motor has afault, there is no stalling event like a common motor, thereby improving the production safety.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a distributed arc motor. Background technique [0002] A DC motor is a motor that converts DC electric energy into mechanical energy. It consists of a stator and a rotor. The stator: base, main magnetic pole, commutation pole, brush device, etc.; rotor (armature): armature core, armature winding, commutation Commutator, rotating shaft and fan, etc.; linear motor is a transmission device that directly converts electrical energy into linear motion mechanical energy without any intermediate conversion mechanism. It can be regarded as a rotating motor cut radially and developed into a plane. Linear motors are easy to support the mover with magnetic suspension, so that the mover and the stator always maintain a certain air gap without contact, which eliminates the contact friction resistance between the stator and the mover, thus greatly improving the system. Excellent sensitivity, r...
