Permanent magnet motors consist of two main types. Surface permanent magnet motors (SPM) and internal permanent magnet (IPM) motors. The main difference is that SPM motors place the magnets on the outside of the rotor while IPM motors place their magnets inside the motor. Benefits to internal magnets include structural integrity and reducing ...
Tesla makes two kinds of electric motors: an induction motor, and an internal permanent magnet (IPM) motor with synchronous reluctance motor (SynRM) characteristics. The older design is a three-phase four-pole alternating current induction motor (also called an asynchronous motor) with a copper rotor (which inspired the Tesla logo). [189]
As an IPM motor, it produces excellent starting torque; however, performance declines at high speeds due to counter-electromotive forces. For high-speed operation, Tesla engineers used iron’s reluctance property, which allows it to spin in synchronization with the magnetic field of the stator if channels are cut into the core. These channels ...
Tesla was incorporated (as Tesla Motors) on July 1, 2003, by Martin Eberhard and Marc Tarpenning in San Carlos, California. [2] [3] [4] The founders were influenced to start the company after General Motors recalled all its EV1 electric cars in 2003 and then destroyed them, [5] and seeing the higher fuel efficiency of battery-electric cars as an opportunity to break the usual correlation ...
The Tesla Model Y is a battery electric compact crossover SUV [5] produced by Tesla, Inc. since 2020. The vehicle was presented in March 2019 as the company's fifth production model since its inception after the Roadster , Model S , Model X and Model 3 .
Tesla carried out the final assembly for European markets at its facilities in Tilburg, the Netherlands, between 2013 and 2021. All versions of the Model S come equipped with a single-speed transmission. The car initially used an alternating current induction motor, but Tesla replaced it with a permanent magnet synchronous reluctance unit in
The Tesla Fremont Factory is an automobile manufacturing plant in Fremont, California, United States, operated by Tesla, Inc. The factory originally opened as General Motors' Fremont Assembly in 1962, and then was operated by New United Motor Manufacturing, Inc. (NUMMI), a joint venture of GM and Toyota from 1984. [1]
"Egg of Columbus" demonstration at the 1893 Columbian Exposition. Tesla's Egg of Columbus was a device exhibited in the Westinghouse Electric display at the 1893 Chicago World's Columbian Exposition to explain the rotating magnetic field that drove the new alternating current induction motors designed by inventor Nikola Tesla by using that magnetic field to spin a copper egg on end.
