What type of motors are generally used for driving new energy vehicles in China?
1 Answers
Domestic new energy vehicles generally use permanent magnet synchronous motors for driving. More knowledge about new energy vehicle drive motors is as follows: Classification of new energy vehicle drive motors: DC motors, AC asynchronous motors, permanent magnet synchronous motors, switched reluctance motors. Characteristics of permanent magnet synchronous motors: Simple structure, small size, light weight, low loss, high efficiency. Compared with DC motors, they do not have the disadvantages of commutators and brushes found in DC motors. Compared with asynchronous motors, they do not require reactive excitation current, resulting in high efficiency, high power factor, large torque-to-inertia ratio, reduced stator current and stator resistance losses, measurable rotor parameters, and good control performance.
