We focus on the characteristics of AC asynchronous motors.
The history of induction (asynchronous) motors:
Nikola Tesla, a power ancestor of the power generation, invented a three-phase alternating current (power) in order to compete with Edison’s DC system, and invented the three-phase AC asynchronous motor of AC, which is Tesla. The originator of the heart of the heart.
In addition, its inventions include Tesla coils, Tesla effects, Tesla transformers (alternating voltage remote power transmission technology), Tesla wireless remote control systems, and the famous Niagara hydropower station. . He has acquired about 1,000 inventions in his life, in various fields of science and engineering.
The current Tesla car is named after this, in fact, it is to pay tribute to this outstanding contributor, and at the same time, it is decided that Tesla will definitely continue to carry forward and carry forward on this motor road.
The entire power heart of an electric vehicle is completely different from an internal combustion vehicle. Generally, an energy storage mechanism (ESS) that stores electrical energy outputs energy to a converter and a power control module (PEM) to drive the execution by sensing the sensor's operational requirements and road conditions. Motor (motor).
Energy storage (ESS)
The automotive energy storage system can only store DC power, while the induction motor uses AC power. To power it, the DC power must first be inverted into AC power. This function is performed by the Power Electronics Module (PEM).
Converter and Power Control Module (PEM)
Tesla's power electronics module uses 72 insulated gate bipolar transistors (IGBTs) to convert direct current to alternating current. In addition to controlling the charge and discharge rates, the power electronics module also controls voltage levels, RPM (revolutions per minute), torque and regenerative braking systems. The brake system typically captures kinetic energy through braking and transmits its feedback back to the ESS (Energy Recovery).
