Problems solved by technology

However, this conventional electric motor has the following disadvantages in use: 1. The rotating speed of the electric motor is controlled solely by the electric power supplied by the storage battery. , the vehicle continues to drive for a shorter time
2. In order to increase the continuous driving ability of the vehicle, some people design to add more than two batteries on the electric vehicle. However, this will inevitably increase the weight burden of the vehicle, and invisibly accelerate the loss of battery power.

Abstract

The magnetic suspension motor for electric vehicle has rotor assembly, electromagnetic pole assembly and loop controlling unit. The rotor assembly has permanent magnet; the electromagnetic pole assembly consists of several magnetic pole coils to produce magnetic poles and the each magnetic pole coil has magnetically conducting coil seat comprising high magnetic inductivity ceramic and high magnetic inductivity silicon steel sheet; and the loop controlling unit has position sensor and loop controller. When the position sensor aligns at the geometric center of the position detecting hole, the magnetic pole coil aligns at the permanent magnet. The position sensor and the magnetic pole coil are connected to the loop controller. By means of the interaction between the electromagnetic coil and the powerful permanent magnet, the present invention can reduce the electricity consumption greatly.

Description

Technical field: [0001] The invention relates to a vehicle driving device, in particular to a magnetic levitation motor of an electric vehicle. Background technique: [0002] At present, people's awareness of environmental protection is gradually increasing, and electric vehicles are gradually widely accepted by people. Because they can reduce the use of gasoline, they naturally reduce environmental pollution. Therefore, electric vehicles are worth promoting. At present, electric vehicles mainly include electric bicycles, electric locomotives and electric cars. The power source of these electric vehicles is to supply the electric motor with the electric power of the storage battery to make it rotate to drive the vehicle to move forward. However, this conventional electric motor has the following disadvantages in use: 1. The rotating speed of the electric motor is controlled solely by the electric power supplied by the storage battery. , the time the vehicle continues to dri...
